JADI PEBISNIS GAK HARUS KAYA, TAMPIL MEWAH, ATAU TERLIHAT WAHH

noreply@blogger.com (Muadz Qiyu) — Tue, 6 Jul 2010 00:52:00 +0700

Menurut saya jadi pebisnis itu gak harus kaya, gak harus mewah ataupun terlihat Wahhh... Karena itu menurut saya hal yang salah. Bisnis itu mudah kok... bisa dilakukan kapanpun dimanapun dan dengan modal berapapun bahkan tanpa modal sekalipun, Intinya hanya niat dan kemauan. Kemauan untuk berusaha dan kemauan untuk mencoba.

Namun selain itu, dalam berbisnis anda juga tentunya harus memikirkan prospek bisnis anda pada tahun yang akan datang, kira-kira bisnis apa yang gak ada habisnya, itu yang perlu anda pikirkan. sehingga anda tidak kehilangan pelanggan.

Contoh saja misalkan Seperti bisnis pulsa, menurut saya itu prospek yang sangat bagus buat anda yang ingin berbisnis dengan modal yang pas-pasan. Pulsa itu gak ada habisnya loh... semua orang sekarang ini pasti banyak yang menggunakan HP, dan pastinya membutuhkan pulsa juga agar bisa berkomunikasi.

Sebagai refrensi, misalkan seperti OtsyPulsa.com, OtsyPulsa adalah penyedia layanan pengisian pulsa 1 Chip All Operator. Jadi anda tidak disibukkan lagi dengan pengisian pulsa yang harus memiliki chip dari banyak operator. Cukup dengan bermodalkan 1 Kartu Perdana dan 1 handphone dan sejumlah uang untuk deposit Saja anda sudah bisa melakukan pengisian pulsa.
Hehehe.. mudah bukan???

Itu dulu aja deh selingan dari saya... yang mau bertanya silahkan bertanya, atau yang mau nambahin silahkan ditambahin. Saya sangat terbuka untuk anda semua...
Ok...Selamat mencoba... Semoga SUKSES Buat anda....

Saya rasa anda semua sering dengar yang namanya PTC... PTC (Paid To Click) adalah model bisnis online. Intinya model bisnis ini menjadi sarana pengubung antara pemasang iklan dan konsumen. Pemasang iklan akan membayar untuk menampilkan sebuah link di situs PTC, Konsumen akan dibayar untuk melihat iklan yang dipasang oleh pemasang iklan tersebut.

Nah.. ngomong2 masalah PTC, disini saya mau sedikit bercerita tentang NEOBUX. Anda pernah dengar NoeBux??
NeoBux adalah PTC N0. 1 Di Dunia, yaitu layanan internasional gratis yang tersedia dalam bahasa Inggris dan bahasa Portugal. Layanan NeoBux memungkinkan pemasang iklan menjangkau ribuan konsumen potensial dengan menayangkan iklan mereka di website NeoBux. User NeoBux mengklik pada iklan dan melihat iklan tersebut dengan batas waktu yang diberikan oleh pemasang iklan. Setelah melihat iklan, userNeoBux mendapatkan “cash” ke account NeoBux mereka.
Untuk menjadi user NeoBux dan mulai mendapatkan penghasilan, TIDAK DIPERLUKAN BIAYA (FREE REGISTRATION). Jumlah pendapatan yang dihasilkan user bervariasi tergantung dari membership, iklan yang dilihat, dan jumlah referral yang dimilikinya.
Contoh:
Standard Member (No Investment) dengan 300 RR (maksimum RR yang diperbolehkan) :

Anda klik 4 iklan setiap hari : 4 x $0.01 = $0.04
Referral Anda klik 4 iklan setiap hari : 4 x $0.005 x 300 = $6

Dalam sehari Jumlah pendapatan Anda + Referral = $0.04 + $6 = $6.04 /hari
Dalam 1 bulan = $6.04 x 30 hari = $181.2 /bln
Dalam 1 tahun = $181.2 x 12 bln = $2174.4

Kalo dirupiahkan :

Misalkan Kurs dollar di ambil Rp.9500,- ,

maka penghasilan Anda adalah :
Perhari = 6.04 x 9500= Rp. 57.380,-
Perbulan = 181.2 x 9500 = Rp. 1.721.400,-
Pertahun = 2174.4 x 9500 = Rp. 20.656.800,-

WAaaooowww....!!!!, sungguh menggiurkan ya???
Hemm... gak usah kebanyakan mikir, kelamaan tar keburu ketinggalan. Langsung gabung aja yuk... Silahkan langsung Klik Disini untuk daftar gratis.

UNSHIELDED TWISTED PAIR (UTP)

noreply@blogger.com (Muadz Qiyu) — Fri, 5 Feb 2010 01:39:00 +0700

UNSHIELDED TWISTED PAIR (UTP)

A. SEJARAH UTP (Unshielded Twisted Pair)
Sebelum kita membahas sejarah kabel UTP, akan lebih baik jika kita mengetahui pengertian dari kabel UTP terlebih dahulu. Kabel UTP (Unshielded Twisted Pair) adalah kabel yang biasa digunakan untuk membuat jaringan atau network computer berupa kabel yang didalamnya berisi delapan buah kabel yang dipilin, dimana setiap kabel mempunyai warna yang berbeda-beda yang digunakan sebagai standart pemasangan kabel jaringan computer, yang setiap pasangnya adalah kembar dengan ujung konektor. Disebut unshielded karena kurang tahan terhadapinterferensi elektromagnetik. Dan disebut twisted pair karena di dalamnya terdapat pasangan kabel yang disusun spiral alias saling berlilitan.

Ada dua macam Twisted Pair, yaitu:
1. Unshielded Twisted Pair (UTP)
2. Shielded Twisted Pair (STP)

· Perbedaan kedua jenis Twisted Pair adalah:
a. STP terdapat lapisan pelindung atau selubung kabel internal.
b. UTP tidak mempunyai lapisan pelindung kabel.

· Kabel UTP lebih terkenal daripada STP, karena kabel UTP lebih sering digunakan
sebagai kabel jaringan.

· Kabel UTP (Unshielded Twisted Pair) ada 2 macam:
1. Untuk kabel telepon yang berisi 4 buah kabel.
2. Untuk jaringan computer yang berisi 8 buah kabel.

· UTP dispesifikasikan oleh organisasi Electronic Industries Association (EIA) dan
Tellecommunication Industries Association (TIA).

· Ada 2 standard untuk strtuktur pengkabelan :
1. EIA/TIA-568 yang dikeluakan oleh Electronic Industries Association dan Telecommunications Industry Association.
2. ISO 11801 yang dikeluarkan oleh ISO.

B. KATEGORI UTP (Unshielded Twisted Pair)

UTP dikategorikan menjadi delapan (7) kategori :
1. Kategori 1
Hanya mampu mentransmisi suara/voice saja, tidak termasuk data.
2. Kategori 2
Kecepatan transmisi data maksimal 4 Mbps.
3. Kategori 3
Kecepatan transmisi data maksimal 10 Mbps.
4. Kategori 4
Kecepatan transmisi data maksimal 16 Mbps.
5. a. Kategori 5
Kecepatan transmisi data maksimal 100 Mbps.
b. Kategori 5 enhanced
Kecepatan transmisi data maksimal 1000 Mbps.
6. Kategori 6
Kecepatan transmisi data maksimal 1000 Mbps.
7. Kategori 7
Kecepatan transmisi data maksimal 1000 Mbps.
Perbedan tiap kategori adalah pada kecepatan transmisi data. Di bawah ini terdapat keterangan Tiap-Tiap Kategori UTP :

Type CAT 1, Type UTP
dengan kategori ini biasanya digunakan untuk perangkat telepon dan digunakan juga
pada jalur ISDN (Integrated Service Digital Networks). UTP dengan jenis ini juga sering digunakan untuk menghubungkan modem dengan line telepon.

Type CAT 2, Type UTP
Kabel ini dapat mentransmisikan data hingga 4 megabit perdetik. UTP dengan kategori ini biasanya digunakan pada jaringan bertopologi token ring.

Type CAT 3, Type UTP/STP
Kabel ini didesain untuk mendukung komunikasi data dan suara pada kecepatan hingga 16
megabit perdetik. Kabel ini menggunakan kawat-kawat tembaga 24-gauge dalam konfigurasi
4 pasang kawat yang dipilin (twisted-pair) yang dilindungi oleh insulasi. Sering digunakan
pada topologi token ring atau 10BaseT.
Type CAT 4, Type UTP,STP
Mentransfer data dengan kecepatan 20Mbit. Kabel ini menggunakan kawat tembaga 22-
gauge atau 24- gauge dalam konfigurasi empat pasang kawat yang dipilin (twisted pair) yang
dilindungi oleh insulasi. Kabel ini dapat mendukung jaringan Ethernet 10BaseT, tapi
seringnya digunakan pada jaringan IBM Token Rin
Type CAT 5, Type UTP, STP-up to100Mhz
Mentransfer data dengan kecepatan 100Mbit. Kabel ini menggunakan kawat tembaga dalam
konfigurasi empat pasang kawat yang dipilin (twisted pair) yang dilindungi oleh insulasi.
Kabel ini telah distandardisasi oleh Electronic Industries Alliance (EIA) dan
Telecommunication Industry Association (TIA).
Type CAT 5enhanced, Type UTP,STP-up to100Mhz
1 Gigabit Ethernet up to 100meters- 4copper pairs.(kedua jenis CAT5 sering digunakan pada
topologi token ring 16Mbps, Ethernet 10Mbprs atau pada FastEthernet 100Mbps) Type CAT
6 up to 155 MHz or 250 MHz 2,5 Gigabit Ethernet up to 100meters or 10Gbit/s up to 25
meters .20,2db(Gigabit Ethernet) Type CAT 7 up to 200 MHz or 700 Mhz (Gigabit Ethernet)
Giga-Ethernet / 20.8 db
Pemberian kategori 1/2/3/4/5/6 merupakan kategori spesifikasi untuk masingmasing
kabel tembaga dan juga untuk jack. Masing-masing merupakan seri revisi
atas kualitas kabel, kualitas pembungkusan kabel (isolator) dan juga untuk kualitas
“belitan” (twist) masing-masing pasang kabel. Selain itu juga untuk menentukan
besaran frekuensi yang bisa lewat pada sarana kabel tersebut, dan juga kualitas
isolator sehingga bias mengurangi efek induksi antar kabel (noise bisa ditekan
sedemikian rupa). Perlu diperhatikan juga, spesifikasi antara CAT5 dan CAT5
enchanced mempunyai standar industri yang sama, namun pada CAT5e sudah
dilengkapi dengan insulator untuk mengurangi efek induksi atau electromagnetic
interference. Kabel CAT5e bisa digunakan untuk menghubungkan network hingga
kecepatan 1Gbps.
C. KEGUNAAN UTP (Unshielded Twisted Pair)
· Sebagai contoh penggunaan kabel UTP untuk sehari-hari adalah kabel telepon. Salah satu
alasan utama mengapa jenis kabel UTP ini sangat popular dibandingankan dengan jenis kabel
lainnya adalah karena penggunaannya kabel UTP sebagai kabel telepon. Banyak gedung
menggunakan kabel ini untuk sistem telepon dan biasanya ada kabel ekstra yang dipasang
untuk memenuhi pengembangan dimasa mendatang.
· Karena kabel ini juga bisa digunakan untuk mentransmisikan data dan juga suara, maka \
menjadi pilihan untuk membangun jaringan komputer. Yang membedakan antara telepon
dengan computer dalam hal penggunakan kabel UTP ini terletak pada jack-nya atau
konektornya.
· Pada komputer digunakan RJ-45 yang dapat menampung 8 koneksi kabel sedangkan pada
telepon digunakan RJ-11, dapat menampung 4 koneksi kabel dan ukurannya lebih kecil.
Lebih jelasnya bisa dilihat koneksi dari telepon Anda yang menggunakan RJ-11.
· Penjelasan Kegunaan Tiap Kategori : 1. Kabel UTP Kategori 1 (Cat1) adalah kabel UTP
dengan kualitas transmisi terendah, yang didesain untuk mendukung komunikasi suara
analog saja. Kabel Cat1 digunakan sebelum tahun 1983 untuk menghubungkan telefon
analog Plain Old Telephone Service (POTS). Karakteristik kelistrikan dari kabel Cat1
membuatnya kurang sesuai untuk digunakan sebagai kabel untuk mentransmisikan data
digital di dalam jaringan komputer, dan karena itulah tidak pernah digunakan untuk tujuan
tersebut.
2. Kabel UTP Kategori 2 (Cat2) adalah kabel UTP dengan kualitas transmisi yang lebih baik
dibandingkan dengan kabel UTP kategori 1 (Cat1), yang didesain untuk mendukung
komunikasi data dan suara digital. Kabel ini dapat mentransmisikan data hingga 4 megabit
per detik. Seringnya, kabel ini digunakan untuk menghubungkan node-node dalam jaringan
dengan teknologi Token Ring dari IBM. Karakteristik kelistrikan dari kabel Cat2 kurang
cocok jika digunakan sebagai kabel jaringan masa kini. Gunakanlah kabel yang memiliki
kinerja tinggi seperti kategori 3, kategori 4, atau kategori 5.
3. Kabel UTP Kategori3 (Cat3) adalah kabel UTP dengan kualitas transmisi yang lebih baik
dibandingkan dengan kabel UTP kategori 2 (Cat2), yang didesain untuk mendukung
komunikasi data dan suara pada kecepatan hingga 10 megabit per detik. Kabel UTP Cat3
menggunakan kawat-kawat tembaga 24-gauge dalam konfigurasi 4 pasang kawat yang dipilin
(twistedpair) yang dilindungi oleh insulasi. Cat3 merupakan kabel yang memiliki
kemampuan terendah (jika dilihat dari perkembangan teknologi Ethernet), karena memang
hanya mendukung jaringan 10BaseT saja. Seringnya, kabel jenis ini digunakan oleh jaringan
IBM Token Ring yang berkecepatan 4 megabit per detik, sebagai pengganti Cat2.
4. Kabel UTP Kategori 4 (Cat4) adalah kabel UTP dengan kualitas transmisi yang lebih baik
dibandingkan dengan kabel UTP kategori 3 (Cat3), yang didesain untuk mendukung
komunikasi data dan suara hingga kecepatan 16 megabit per detik. Kabel ini menggunakan \
kawat tembaga 22-gauge atau 24- gauge dalam konfigurasi empat pasang kawat yang dipilin
(twisted pair) yang dilindungi oleh insulasi. Kabel ini dapat mendukung jaringan Ethernet
10BaseT, tapi seringnya digunakan pada jaringan IBM Token Ring 16 megabit per detik.
5. Kabel UTP Kategori 5 (Cat5) adalah kabel dengan kualitas transmisi yang jauh lebih baik
dibandingkan dengan kabel UTP kategori 4 (Cat4), yang didesain untuk mendukung
komunikasi data serta suara pada kecepatan hingga 100 megabit per detik. Kabel ini
menggunakan kawat tembaga dalam konfigurasi empat pasang kawat yang dipilin (twisted
pair) yang dilindungi oleh insulasi. Kabel ini telah distandardisasi oleh Electronic Industries
Alliance (EIA) dan Telecommunication Industry Association (TIA). Kabel Cat5 dapat
mendukung jaringan Ethernet (10BaseT), Fast Ethernet (100BaseT), hingga Gigabit Etheret
(1000BaseT). Kabel ini adalah kabel paling populer, mengingat kabel serat optik yang lebih
baik harganya hamper dua kali lipat lebih mahal dibandingkan dengan kabel Cat5. Karena
memiliki karakteristik kelistrikan yang lebih baik, kabel Cat5 adalah kabel yang disarankan untuk semua instalasi jaringan. Kategori Enhanced 5 Kabel ini merupakan versi perbaikan dari kabel UTP Cat5, yang menawarkan kemampuan yang lebih baik dibandingkan dengan
Cat5 biasa. Kabel ini mampu mendukung frekuensi hingga 250 MHz, yang
direkomendasikan untuk penggunaan dalam jaringan Gigabit Ethernet, meskipun
menggunaan kabel UTP kategori 6 lebih disarankan untuk mencapai kinerja tertinggi.

STORE PROCEDURE

noreply@blogger.com (Muadz Qiyu) — Fri, 5 Feb 2010 01:11:00 +0700

A. Teori Singkat
Store Procedure adalah kumpulan dari perintah Transact-SQL yang dikompile dalam satu unit untuk dijalankan bersama. Dalam SQL Server store procedure memiliki kemampuan antara lain :
• Menerima parameter input dan mengembalikan beberapa nilai parameter output dari procedure yang dipanggil.
• Mengandung statement pemrograman yang melakukan operasi terhadap database termasuk memanggil store procedure lain.
• Memberikan status yang mengindikasikan keberhasilan atau kegagalan eksekusi store procedure Keuntungan pemakaian store procedure adalah :
• Merupakan pemrograman modular
Store procedure dibuat sekali dan dapat dipakai berulang untuk komputasi yang sama
• Memungkinkan eksekusi lebih cepat
Ketika pertama kali dijalankan store procedure akan tersimpan dalam memori. Sehingga memungkinkan eksekusi berikutnya lebih cepat.
• Mengurangi trafik jaringan
Barisan kode transact SQL yang seharusnya dilewatkan jaringan, akan digantikan dengan statement tunggal pemanggilan store procedure
• Dapat digunakan sebagai mekanisme sekuriti
Pengguna dimungkinkan mengeksekusi Store procedure, walau mungkin tidak dapat mengeksekusi procedure didalamnya secara langsung.

Sebelum mempelajari cara pembuatan store procedure, perlu juga dipelajari statement Transact SQL untuk pemrograman server. Beberapa statement Transact SQL :

PERMUTASI DAN KOMBINASI Matematika Diskret,

noreply@blogger.com (Muadz Qiyu) — Wed, 3 Feb 2010 22:30:00 +0700

DASAR PENGHITUNGAN
|A| : jumlah elemen dalam himpunan A
Aturan Penjumlahan:
|A| = |S1|+|S2|+|S3|+ . . . . .+|Sn|, dimana himpunan-himpunan bagian (S1, S2,..., Sn) semuanya saling asing
Aturan Perkalian:
suatu pekerjaan melibatkan k buah langkah
langkah 1 - dengan n1 cara
langkah 2 - dengan n2 cara
................
langkah k - dengan nk cara
Maka keseluruhan pekerjaan dapat dilakukan dengan: (n1) (n2) (n3).... (nk) cara

Contoh 1:
Dalam suatu kartu bridge, berapa cara untuk mengambil:
a. Sebuah jantung atau sebuah daun
b. Sebuah jantung atau kartu As
c. Sebuah As atau King
d. Sebuah kartu bernomor 2 hingga 10
JAWAB:
a. Karena antar gambar kartu adalah saling asing, maka banyak cara mendapatkan
= 13 + 13 = 26 cara
b. Banyak cara = 13+3 = 16 cara
c. Banyak cara = 4+4 = 8 cara
d. Banyak cara = 9+9+9+9 = 36 cara

Contoh 2:
Misal 2 dadu yang berbeda warnanya dilontarkan. Ada berapa cara untuk mendapatkan jumlah angka 4 atau 8
JAWAB:
- Cara mendapatkan jumlah angka 4 ada 3 cara
- Cara mendapatkan jumlah angka 8 ada 5 cara
Sehingga untuk mendapatkan jumlah angka 4 atau 8 ada : 3+5 = 8 cara

Contoh 3:
Jika 2 buah dadu yang berbeda dilontarkan, berapa banyak kemungkinan angka yang muncul?
JAWAB:
Sebuah dadu mempunyai 6 kemungkinan kemunculan angka-angka, sehingga kalau 2 buah dadu ada: 6*6=36 cara
(Jika ada n dadu, ada 6n kemungkinan)

Contoh 4:
Suatu kode terdiri dari 3 huruf dan diikuti 4 angka, contoh BAC4321.
a. Jika baik huruf atau angka dapat diulangi penggunaannya, ada berapa kode berbeda yang dihasilkan
b. Bagaimana jika hurufnya saja yang boleh diulang
c. Bagaimana jika huruf maupun angka tidak boleh diulang
JAWAB:
a. Banyak cara = 26*26*26*10*10*10*10 = 263*104
b. Banyak cara = 263*10*9*8*7
c. Banyak cara = 26*25*24*10*9*8*7

Contoh 5:
Berapa banyak bilangan yang terdiri dari 2 atau 3 digit dapat dibentuk dengan menggunakan angka-angka 1,3,4,5,6,8 dan 9, jika perulangan tidak diperbolehkan
JAWAB:
Banyak cara : 7*6 + 7*6*5 cara

PERMUTASI

- Urutan diperhatikan
- Perulangan tidak diperbolehkan
- Dinotasikan:

- Bila r=n, mana P(n,r) = n!

Contoh 6:
Dalam suatu kelas ada 20 orang. Berapa cara untuk memilih ketua dan bendahara
JAWAB:
Banyak cara = 20*19 =380 cara (urutan diperhatikan)
(hal ini akan berbeda jika akan dipilih 2 orang wakil kelas, karena urutan tidak diperhatikan)

Contoh 7:
Tuliskan semua permutasi 3 objek {a,b,c}
JAWAB:
Ada 3! = 6 kemungkinan, yaitu:
abc, acb, bca, bac, cab, cba

Contoh 8:
Suatu undian menggunakan 7 digit angka, jika digit-digitnya harus berbeda dengan yang lain, ada berapa kemungkinan nomor undian?
JAWAB:
P(10,7) =10!/3! = 10.9.8.7.6.5.4 macam kemungkinan

KOMBINASI

- Urutan kemunculan tidak diperhatikan
- Dinotasikan

- Bila r=n, mana C(n,r) = 1

Contoh 9:
Berapa tim Basket yang dapat dibentuk dari 12 orang?
JAWAB:
Urutan pemain tidak diperhatikan (abc = bac)
Jadi, banyak tim:

INDUKSI MATEMATIKA (Matematika Diskret)

noreply@blogger.com (Muadz Qiyu) — Wed, 3 Feb 2010 22:06:00 +0700

Induksi Matematika digunakan untuk mengecek hasil proses yang terjadi secara berulang sesuai dengan pola tertentu. Suatu teknik yang dikembangkan untuk membuktikan pernyataan. Perhatikan kasus berikut:
“Beberapa orang Amerika mengusulkan agar pemerintah menghentikan pengeluaran koin 1 sen (1¢), karena selain nilainya terlalu kecil, harga-harga barang yang sama atau lebih dari 4 ¢ dapat dibayar dengan koin 2 ¢ atau 5 ¢ (tanpa memerlukan koin 1 ¢)”

Secara formal dapat dikatakan:
“Untuk setiap bilangan bulat n≥4, n sen dapat diperoleh dengan koin 2¢ dan 5¢”

Perhatikan tabel berikut:

Baris ke-k dalam tabel tersebut adalah untuk mendapatkan (k+3) ¢ dengan menggunakan koin 2 ¢ dan 5 ¢.

Untuk melanjutkan pembuatan tabel berikutnya haruslah dibuat aturan bagaimana mengisi baris ke-(k+1), dengan menggunakan pola baris ke-k.

Ada 2 kemungkinan:
1. Ada koin 5 ¢ yang digunakan untuk menyusun
atau
2. Semua koinnya adalah 2 ¢

Jika ada 5 ¢ yang digunakan untuk menyusun k-koin, maka untuk menyusun (k+1) koin:

- gantilah koin 5 ¢ dengan 3 buah koin 2 ¢, sehingga jumlah seluruhnya (k+1) koin.
atau
- gantilah 2 buah koin 2 ¢ yang nilainya 4 ¢, dengan 5 ¢, sehingga seluruhnya (k+1) koin

Dari contoh tersebut:

Tunjukkan bahwa P(4) benar
dengan kata lain: 4 ¢ dapat disusun dengan koin 2 ¢ dan 5 ¢

Tunjukkan kebenaran P(k+1) bisa didapatkan dengan diketahuinya kebenaran P(k)

dengan kata lain:

misalkan k ¢ dapat disusun dengan koin 2 ¢ dan 5 ¢, maka ditunjukkan bagaimana (k+1) ¢ didapatkan dari koin 2 ¢ dan 5 ¢

Disimpulkan:
Misalkan P(n) adalah pernyataan yang yang didefinisikan dalam bilangan bulat n dan a adalah bilangan bulat tetap, maka:
P(a) benar
Jika P(k) benar, maka P(k+1) benar, untuk k ≥ a

Sehingga: P(n) benar untuk semua n ≥ a
Langkah 1 disebut Basis
Langkah 2 disebut Langkah Induksi

Contoh Kasus:
Buktikan bahwa:

Kick-deflect invasion Email Senders

noreply@blogger.com (Muadz Qiyu) — Sat, 26 Dec 2009 12:05:00 +0700

Junk email, aka spam is hard muted, especially if the email that we use do not use a filter spam filter. Inevitably, the ads brought gelontoran unwanted messages are going mensesaki our inbox.

Here are some tricks that can be done to ward off invasion recommended Symantec email:

Who should do:

Unsubscribe from legitimate mailing-list if you do not want to receive messages again. When registering to receive email, check out additional items whatever you want at the same time. Do not select the items you want.

Selective in terms of sites where you register your email address.

Avoid displaying your email address on the Internet. Consider alternative options-for example, use a separate address when registering at a particular mailing list, have several email addresses for many different purposes, or look for a disposable email service.

By using the instructions provided by the administrator, report spam if you have the option to do so.

Delete all spam.

Avoid clicking on suspicious links in emails or IM messages, because it could be connected to a fake site. We recommend to type a website address directly in the browser rather than trust the link in the message.

Ensure that the operating system up to date, and use security software packages are comprehensive.

Consider the anti-spam solution that has a good reputation for handling filtering throughout your organization.

Who should not do:

Opening an email attachment from an unknown. This appendix can infect your computer.

Replying to spam. Usually forged email address, and reply to email spam will result in another spam spam.

Fill out the form in a message requesting personal or financial information or passwords (passwords). Leading companies can not ask for your personal information via email. If you hesitate to contact the company through a trusted independent mechanism, such as by verifying the phone number or Internet address is known that you type into a new browser window (do not click on or cut and paste the link in the message).

Buying products or services from spam messages.

Open the spam message.

Forward any virus warnings you receive by email. It could be a lie that is the news (hoaxes).

Jurus Menangkis Serbuan Email Sampah

noreply@blogger.com (Muadz Qiyu) — Sat, 26 Dec 2009 10:02:00 +0700

Spam alias email sampah memang sulit diredam, apalagi jika email yang kita gunakan tidak menggunakan filter penyaring spam. Niscaya, gelontoran iklan yang dibawa pesan yang tak diinginkan tersebut bakal mensesaki inbox kita.

Berikut beberapa jurus yang bisa dilakukan untuk menangkis serbuan email yang direkomendasikan Symantec:
Yang Sebaiknya Dilakukan:

Berhenti berlangganan dari milis-milis sah jika Anda tidak ingin menerima pesan lagi. Ketika mendaftar untuk menerima email, periksa item-item tambahan apa saja yang Anda inginkan pada saat yang sama. Jangan memilih item yang tidak Anda inginkan.

Selektif dalam hal situs-situs tempat Anda mendaftarkan alamat email Anda.

Hindari menampilkan alamat email Anda di Internet. Pertimbangkan pilihan alternatif- misalnya, gunakan alamat tersendiri ketika mendaftar pada milis tertentu, miliki beberapa alamat email untuk berbagai tujuan berbeda, atau carilah layanan email sekali pakai.

Dengan menggunakan petunjuk yang disediakan oleh administrator, laporkan spam jika Anda memiliki pilihan untuk melakukannya.

Hapus semua spam

Hindari mengklik pada link mencurigakan dalam email atau pesan IM, karena bisa saja akan menghubungkan ke situs palsu. Kami menyarankan untuk mengetik alamat situs langsung pada browser daripada percaya pada link dalam pesan.

Pastikan bahwa sistem operasi selalu up to date, dan gunakan paket software keamanan yang komprehensif.

Pertimbangkan solusi antispam yang memiliki reputasi baik untuk menangani penyaringan di seluruh organisasi anda.

Yang Sebaiknya Tidak Dilakukan:

Membuka lampiran dari email yang tidak dikenal. Lampiran ini dapat menginfeksi komputer Anda.

Membalas spam. Biasanya alamat emailnya dipalsukan, dan membalas email spam akan menghasilkan spam-spam lain.

Mengisi formulir dalam pesan yang meminta informasi pribadi atau keuangan atau kata sandi (password). Perusahaan terkemuka tidak mungkin meminta informasi pribadi Anda melalui email. Jika ragu untuk menghubungi perusahaan yang bersangkutan melalui mekanisme independen yang terpercaya, seperti dengan memverifikasi nomor telepon atau alamat Internet yang dikenal yang Anda ketikkan ke jendela browser yang baru (jangan mengklik atau cut dan paste dari link dalam pesan).

Membeli produk atau jasa dari pesan spam.

Membuka pesan spam.

Meneruskan peringatan virus apapun yang anda terima melalui email. Bisa jadi itu adalah berita bohong (hoax).

5 Tahap Sederhana Menganalisis Virus Komputer

noreply@blogger.com (Muadz Qiyu) — Sat, 26 Dec 2009 09:44:00 +0700

Pernahkah direpotkan oleh virus yang menyerang komputer Anda? Sementara update antivirus kita belum mampu mengenali program jahat yang mangacau tersebut. Mengapa tidak mencoba iseng-iseng menganalisis sendiri? Ini dia tahap sederhananya.

Adang Juhar Taufik, Senior Vaksinis Vaksincom dalam seminar Vaksincom bertempat di Ancol, Jumat (4/12/2009), memberi penjelasan betapa sederhananya tahapan analisis virus yang menyusup pada komputer bersistem operasi Windows, khususnya jika yang menyerang virus lokal.

"Untuk virus lokal sendiri sebenarnya mudah untuk menganalisisnya, karena pasti karakterisitknya sama," ujarnya. Adang pun mengatakan bahwa pertama kita harus memiliki internet, untuk mencari tools-tools yang secara gratis bisa diunduh di beberapa situs.

Selain itu virus lokal juga bisa dilihat melalui list proses Windows melalui task manager, untuk melihat jenis file aneh yang running. Di samping itu kita juga bisa menganalisanya melalui registry tools (reg. edit).

"Untuk user yang lebih advanced ada 2 tools yang mungkin bisa digunakan yakni pack detection dan unpack program serta VB decompiler. Karena biasanya virus lokal berbasis VB," tambahnya.

Adang pun menjelaskan setelah kita memiliki tools-tools tersebut, kita bisa mulai menganalisa dengan tahapan-tahapan yang sederhana:

1. Pahami dulu jenis virus yang menyerang:
Icon apa yang disamarkan serta ukurannya.
2. Pahami karakteristik virus.
Apakah membuat file duplikat, menyembunyikan file, menginjeksi file, atau menampilkan pesan tertentu.
3. Pahami cara kerja virus:
Apa yang diubah virus, apakah registry, file induk yang dibuat, atau fungsi windows yang diblok.
4. Pahami penyebaran virus:
Apakah melalui USB flash disk atau folder yang di share, karena biasanya virus lokal menyusup melalui 2 media tersebut.
5. Siapkan beberapa tools yang digunakan.

Hack komputer orang lewat jaringan LAN

noreply@blogger.com (Muadz Qiyu) — Thu, 24 Dec 2009 09:29:00 +0700

Cara masuk di komputer lain lewat DOS (Windows XP / 2000)
Ente ingin masuk dikomputer teman melalui sebuah LAN ? bisa melihat seluruh isi harddisk teman ente, membuat directory, membuat file, mendelete file atau apa saja ? itu mudah, semua caranya ada disini.

Pertama-tama anda harus tahu 2 program penting lalu downloadlah yaitu internet Maniac (Internet Maniac.exe) … Download Internet. Berfungsi untuk mengetahui ip addreas client melalui computer name / hostname
KaHT (KaHt.exe) … Download program hacker. Berfungsi sebagai program untuk menerobos ke computer server atau client.
Ingat hanya dengan 2 program diatas maka anda bersiap-siaplah menguasai warnet / kampus / kantor dan sebagainya, lho bagaimana bisa ? hehe...
Pertama kali anda periksa dahulu jaringan anda dengan melihat para hostname dengan 2 cara.

Untuk Windows XP
Cara Pertama Masuk ke Start Lalu Search, lalu pilih computers or people lalu pilih A computer on the Network lalu langsung klik search maka akan segera muncul computer-komputer yang terkoneksi dalam jaringan.
Untuk Windows 95/98/Me/2000 (kalau anda menemukan open port 135 di OS ini)
Cara Pertama Masuk ke Start Lalu Search Lalu For Files or Folders lalu pada menu Search for other item pilihlah computers, lalu akan muncul Search for computer, maka langsung klik Search Now maka nama-nama computer akan muncul (Alternatif cara yang cepat dapat mengklik My Network Place / Network Neighboure saja).
Setelah enteh dapetin sasaran computer yang mau di masukin / diremote maka ente langsung aja jalankan program Internet Maniac Masuklah ke Host Lookup lalu ketikkan nama computer / hostname lalu klik resolve, disini anda akan mendapat alamat ip computer tersebut. Dengan nomor ip ini maka anda sudah mengetahui sasaran computer yang akan di masuki. Setelah itu selesai maka kita tinggalkan program Internet Maniac, kita akan berlanjut dengan program KaHT, program ini akan didetect sebagai Trojan oleh antivirus, tapi abaikan saja, jangan di hapus / di karantina kalau terdetect, kalau perlu del aja antivirusnya, satu lagi, program KaHT bekerja dalam MS-DOS Mode jadi disini kemampuan anda menggunakan DOS sangat penting, tanpa kemampuan DOS maka anda tidak akan bisa banyak berbuat.

Cara masuk DOS Mode Untuk Windows XP :
Masuklah ke Start, All programs, Accessories lalu Command Prompt
Untuk Windows 95/98/Me/NT/2000,
Masuklah ke Start, Programs, Accessories lalu MS-DOS Prompt
Setelah berhasil masuk DOS maka masuklah di directory program KaHT, (Misal tadi di C:\KaH) maka ketikkan “CD\KaHT” dan seterusnya.
Jika sudah, ini saatnya?
Ketikkan “KaHT sebelum_no_ip_komputer_sasaran no_ip_komputer_sasaran.
kalau bingung bisa begini : “KaHT Ip1 ip2?
ip1 : ip awal yang discan
ip2 : ip terahkir yang discan

Misalnya tadi ip-nya 192.168.0.1 setelah di detect pakek Internet Maniac tadi itu lho.
Maka ketikkan saja “KaHT 192.168.0.0 192.168.0.1? lalu enter aja Nah disini nanti program akan bekerja otomatis.
Setelah selesai menscan jika nanti port 135 ternyata dalam keadaan open maka anda akan otomatis di computer tujuan / sasaran, untuk lebih persisnya anda akan berada di “c:\windows\system” milik komputer tujuan / sasaran setelah pen-scan-an selesai.
ente bisa bebas di computer sasaran, mau edit atau di delete pun bisa, hehe Nah kalo udah begini kita bisa berkreasi :

Memata-matai anak yang sedang chatting pakek MiRC di satu warnet / kampus / kantor / lainnya, cari program MiRC yang digunakan dalam computer tersebut, biasanya seh di C:\Program Files\MiRC, buka file MiRC.INI, lalu Log IRC di On kan saja dan kalo mau lihat isi chattingan teman kita itu cukup lewat “/logs” maksudnya kalau tadi di C:\program Files\MiRC program MiRCnya maka cukup masuk aja di C:\Program Files\MiRC\Logs nanti disitu ada file-file log hasil chattingan dia walaupun dia sedang online tetep aja terekam, hehe, kalo mau mastiin dia makek nick apa, gampang banget bisa jalanin aja MiRCnya atau periksa di MiRC.INI, gampangkan.
Apalagi nih, Bikin computer itu rusak, lebih baik jangan, tapi sebenere bisa lho, delete aja file-file systemnya, hehe.
Diatas cuman kreasi dikit aja, loe bisa aja memanfaatkannya jauh lebih bermanfaat dari pada diatas Tujuan dari tutorial ini untuk anda yang sering menggunakan komputer dengan Windows 2000 dan XP dijaringan agar lebih waspada terhadap berbagai tindakan usil dari pihak-pihak yang tidak bertanggung jawab..

Membuat akses administrator Windows untuk kita lewat komputer lain.
Kita ingin membuat administrator Windows XP/2000 di komputer lain melalui LAN ? sangat mudah, caranya masuklah ke komputer tujuan dengan program kaht yang sudah diajarkan diatas, lalu kita akan mencoba beberapa trik.

Melihat akses guest dan administrator di Windows
Ketik : net user Melihat aktif tidaknya guest di Windows
Ketik : net user guest Membuat akses guest menjadi Administrator dengan perintah :
Ketik : net localgroup Administrators Guest /add

Membuat akses adminstrator sendiri :
1. Ketik : net user /add
2. Ketik : net localgroup Administrators /add

Menghapus akses administrator
Ketik : net localgroup Users /delete

Catatan:
*Tidak untuk disalahgunakan dan hanya untuk pembelajaran
*Tindakan ini mungkin berbahaya jadi pikirkan dulu 100 X sblum mencobanya
*Tidak disarankan untuk pemula atau yg tidak bs memperbaiki PCnya sndiri
*Segala kesalahan error / kerusakan pada komputer dan semacamnya adalah tanggung jawab anda !
*Semua yang anda pelajari dan anda lakukan adalah sepenuhnya tanggung jawab anda tanpa kecuali.

jadi sebaiknya jgn dilakukan bila perlu!!

Auditing Network Security System

noreply@blogger.com (Muadz Qiyu) — Fri, 18 Dec 2009 04:08:00 +0700

Audit system is one of the stages in order to ensure that "security goal" is maintained properly. After all policies related to computer network security made by an organization, then the next stage is to test whether all the policies and rules that have made it had correctly applied or not.
There are 3 types of audits are usually done on network security systems within an organization, namely:
1. "Audit privilege" that would audit how the permissions settings applied at the company's appropriate or not and how the implementation in the field.
2. "Usage audit" bagaiaman audit of resource use within the organization. Is it in accordance with the policy of the organization or not.
3. "Escalation audit" to audit how the security system in an organization facing a critical situation. For example how fast the system recoveri process in the event of an attack by "hackers", how the standard operating procedures applied by the organization if a problem occurs on a network system infrastructure, how to cope in the event of natural disasters. So from all of the audit process can identify weaknesses anything contained in the computer network systems organization. To further search can be an appropriate solution to deal with these problems.

Analysis of factors affecting students in choosing the college of management information systems and computer science "amikom" yogyakarta

noreply@blogger.com (Muadz Qiyu) — Tue, 8 Dec 2009 02:54:00 +0700

The need for education has been more crucial in employment competition lately in view of the fact that human resource selection by employers is based on certain education level and expertise relevant to the occupational preference. The College of Management Information Systems and Computer Science (STMIK) AMIKOM Yogyakarta as a Private Higher Educational Institution is aimed at achieving the goals of national education by accomplishing the Triadic Function of Higher Education (Tridharma Perguruan Tinggi) including education, research and community services.

Qualitative data were analyzed and described in percentage and presented in form of tables based on the respondents' responses in both numeric and non-numeric data. Quantitative analysis was conducted by testing a group of variables that was appropriately considered as a factor based on the criteria that the Eigen value should be greater than or equal to unity. The contribution of each factor to decision-making process was viewed from the total value of variance for each factor. Whereas, the role of each variable within a factor was determined by the loading factor of the respective variable, where the variable with the greatest loading factor would have the main role within the factor.

The results of analysis on service, facility and marketing mix factors considered by the students in their preference and admission to the College of AMIKOM Yogyakarta showed that all factors deserved to consider. Twenty-two variables under consideration were grouped into 6 factors, i.e., service, facility, promotion, price, product and campus location.

Among 6 factors considered by the students in their preference and admission to the College of AMIKOM Yogyakarta, the factor of service delivered by the College management constituted the most crucial factor with a variance value of 22.880%, indicating that 22.880% of student candidates would consider the service delivered by the college management; then followed by the factor of facility 8.348%; the factor of promotion 7.593%, the factor of price 7.377%; the factor of product 6.736%. Whereas the location of AMIKOM campus at Jalan Ring Road Utara constituted the least significant consideration with a variance value of 5.430%, indicating that 5.430% of student candidates would consider the campus location.

The percentage of cumulative variance contribution of the six factors considered by the students in their preference and admission to the Collage of AMIKOM Yogyakarta was 58.565. It indicated that the six factors were able to account for the variables considered by the students or consumers in their preference and admission to the College of AMIKOM Yogyakarta to the extent of 58.365%. The remaining percentage of 41.635% was explained by variables outside the model.

Further research is recommended in view of the limitation of this study that merely considered and tested the variables of service, facility and marketing mix. Conceptually, there are many other variables considered by student candidates in their preference and admission to the College of AMIKOM Yogyakarta such as cultural, socio-political, economic, technological factors and others.

Excess among flexibility offered, because to implement wireless LAN technology is not constrained topology problems / conditions. This technology can be applied in which Just to reach a good signal depends on the quality of the device wireless LAN is used. Along with the many users of technology wireless-based network, then the more the parties trying to do a "crime" of this network.

This can be seen from the number of software / tool that was created to take the offensive for both wireless networks was the kind of active attacks and passive types of attacks. Such software is usually distributed through the internet for free and There are also some who paid. Requiring a security method the right to address security issues for wirelessLAN network.

Wireless networks are vulnerable to attack, it is because network with this technology can not be confined by a building like that in cable-based network protected by a wall in a building cable-based network which is attached. Radio frequency signals used by the wireless network in the data transmission process in these networks can be easily accepted / in caught by user other than the user's computer wireless network is only with using a wireless network card compatible / fit with the network wireless is installed on the computer user's computer. Security holes in wireless networks can be divided into 2 (two) types of attack, namely: passive attacks and active attacks.

Passive Attack
Passive attack is a real type of attack does not endanger of a network system. This type of attack does not cause loss of resources in a network or causes damage to the a network of systems that were attacked using this type of attack. Source power contained in the system including a data network, bandwidth network, printer, memory in a computer processing unit (processor) and more. The point of this attack is only to observe the all the resources contained in a computer network system. like network traffic monitor a computer network system. Information resulting from these observations is very useful for those who do not reserves the right to conduct further attacks against the system. so that this type of attack is very difficult to detect by the manager of a computer network systems. Wireless network communications are usually used common radio frequency that is not listed that can be accessed by anyone with a compatible network card. so to This type of network is very easy to tap by using the technique of "sniffing" or "wardriving". We have a lot of "sniffer" using software such as NetStumbler in combination with each other antennas work together with the card wireless network (wireless) to detect the network "access points" (AP) which in range and the signal can be accessed wirelessly network card it. Then the data traffic is happening in the wireless network in captured by the "sniffer" for later in the analysis by using tools such as Microsoft Network Monitor to microsoft windows operating system or using TCPDump to Linux Linux operating system.

Programs such as NetStumbler but can be used to detect network access point located within range can also be used to displays the information on the Service set identifiers (SSID) and manufacturer information access point is. So if the Access Point remain in the configuration is still using the default SSID settings are included by the manufacturer when the access point is purchased, then the wireless network use the access point device is very susceptible to problems security.

If the SSID contains information about organizations that provide services wireless network or the network may not use security methods such as encryption by Wireless Equivalent Privacy (WEP) is capable of doing encryption of all data traffic that occur within the wireless network, if it happens the right network security it would be easy to pass by the parties who are not interested (unauthorized users). Once a "sniffer" managed to get the SSID information an access point, the "sniffer" that can take pictures of traffic in wireless network and open information about all the things in the network these, such as user name and password. When a sniffer successfully perform have observed and use the information obtained to entered into the network and accessing or using the resources within system without permission, then at this stage passive attacks (passive attack) turned into a kind of active attacks (active attack).

To protect wireless networks against computer programs that mengeteksi existence capable wireless network signal, then a manager wireless networks (administrator) to do the reconfiguration of all the basic configuration of the wireless network device if the configuration is still using a standard onfiguration / defaults provided by the vendor maker wireless network devices such as the device was first purchased. Among them is to implement a security system that is closed with how to configure an Access Point that can not respond connection requests (request) to the status of his SSID that is usually requested by programs such as NetStumbler. In this way an access point in a fixed wireless network can not be detected (invisible) by the parties not entitled to access the wireless network.

Currently most devices access point for wireless network very easy to its configuration in order to facilitate its users and using the network. But with all these facilities was has weaknesses, too. By prioritizing ease of configuration, then some makers access point vendors do not provide a touch of aspects security in the basic configuration provided on the access point they production. This is due to the configuration of security in a network access point device is quite complicated and must consider many aspects. So if the included network security into the basic configuration of access point devices must process is not easy longer and requires special skills of the user.
Here are some basic things that can be done to protect the network wireless passive attacks and active attacks:

1. Secure the wireless router or interface page Administrator Access Point.
Almost all routers and access points have the password for the administrator required at the time of login into the wireless device and to make configuration settings in the access point device. Most access point device using the default password is very simple and not safe. For example the password with the keyword "password" as well or use keyword company names, and some even do not has a password at all. In such cases, the first step performed by an administrator during the first setting wireless router to the device or access point is to change The default password on the device with another password more secure. Because this password is rarely used because to do configuration the access point device is usually very rarely done, then use a password that is easy to remember but difficult to guess or can also be a way to write these passwords are not easily forgotten but stored in a safe place if it is to passsword written so as not to forget. If finally the password is forgotten then satusatunya way is to reset the access device point is that all the onfiguration is returned to the default configuration as previously when the wireless device was first purchased from the vendor.

So the administrator must do the reconfiguration of the device to aspects of wireless security.
Here are a few tricks to create a relatively secure password:
• passwords do not use personal information such as name, date of born.
• passwords must be easy to remember but difficult to predict.
• use a different password to access the system different.
• change the password regularly to prevent attacks on password using the program "password cracking".
• if the password should be written and stored in a computer file because it is difficult to remember so keep a safe place and files is the encryption.

2. Do not Make Broadcast of SSID access point.
Most access points and routers automatically broadcast process for the network name, or SSID (Service Set Identifier). This setting is of course facilitate the wireless network settings on the client and create a device access point can be seen by all wireless network systems are included in coverage access point device is. So by activating SSID on the access point that allows all parties to detect presence of a network access point is either by the party entitled or by parties who are not entitled to access the network. This is of course can lead to security holes in wireless networks are. To securing the feature should disable SSID broadcast on the network so that wireless is to become invisible (invisible) by the other users who do not eligible and not enrolled in these wireless networks. For ordinary users this This can not be detected, but for a "sniffer" of course this does not influential because by using computer programs specific like NetStumbler the "sniffer" can still detect the presence of the device access point for the wireless network.

3. Security Features Enable WPA encryption instead of WEP.
Keamaanan features WEP encryption (Wired Equipment Privacy) which during the many applied to the access point device has been known to have many weakness that is relatively easy for someone to open the code encryption and access the wireless network using only appropriate device. A better way to protect wireless networks current is to use WPA (Wi-Fi Protected Access). WPA provides more security features and ease of its use, unlike the WEP limit the use of characters password only on the numbers 0-9 and letters from AF. Support for WPA have been included in the operating system Windows XP (with latest service packs)

and virtually on the latest wireless networking devices today and in operating system. The latest version of the current WPA WPA2 which is to be found on the latest wireless network devices today and provides a mechanism better encryption. But to use this feature may be WPA2 must download the latest patch on Windows XP operating system. Because feature This relatively new and not all Windows XP operating system supports use.

4. Use WEP than not using at all.
If you find that there are several wireless devices on the market today only supports WEP encryption key (usually found on the device non-PC based such as media players, PDAs, and DVR), then use this feature WEP encryption, although relatively safe than not at all and use keys that are difficult to predict.

5. Use filtering to control access to wireless networks with using MAC filtering.
Unlike the use of IP address, MAC address of a unique nature to distinguish between one network device to another one. So that the switch uses MAC filtering feature it can be limited access to the wireless network by only those MAC addresses his MAC address of each user in the wireless network must be known first 12 characters are the MAC address of each network devices that will connect to the access point device.

Of course this means a little uncomfortable and inflexible because of a administrator must register all MAC addresses for each user / client which will be connected into the network. If the number of client users wireless network is of course a lot of trouble a administratori network. We have had many programs including the category of "hacking tools" which can be used to make counterfeiting / "spoofing" the address MAC. Necessitating careful enough attention from an administrator wireless network to determine which MAC addresses are valid and which addresses MAC false. So with falsified / MAC address spoofing in accordance with MAC address listed in the wireless network is the is not entitled to enter and access these wireless networks.

6. Reducing the beam power wireless devices (access points).
This feature is not available in all wireless routers and access points, but there are some wireless devices that provide features for lower power wireless devices in the transmit signal so that the narrower the range of the signal. Although not always possible to make the process of setting appropriate to the size of the signal but this still managed to reduce the potential for gaps security on wireless network system and minimize the chance of outside parties systems that are not entitled to access the wireless network device.

7. Turn off the features / remote administration service.
Almost all wireless routers provide the device features to be managed remotely through the Internet. Ideally, the use of this feature when deciding on a specific IP address or to limit the reach the use of IP addresses that may access the router device. instead for the two activities mentioned above, this feature should be disabled. because the This feature will enable everyone in range signal wireless router device has the potential to discover and access these wireless router devices. So that always turn off this feature as a policies in the management of the router device in a wireless network. So that an administrator can not perform network management wirelessnya remotely via the Internet. This feature is usually disabled by default by the vendor making the router device when it was first purchased for security reasons. But it never hurts to check on a regular basis against this feature in a wireless network device if it is true been disabled or still active.

Conclusion
Wireless network is a computer network is very open and vulnerable the security hole. This is due to constituent components This network is physically very difficult to secure. In contrast to the network cable-based physical security for the secured easily and at control, wireless-based networks is very difficult to control. Transmitting frequency signals used by wireless device allows all parties can detect and access this network while using the compatible wireless receiver and the signal can reach. Today many all types of computer programs that can be used to perform attacks on wireless networks, both types of passive attacks that nature does not destroy and steal just to the type of information to active attacks that can damaging the system and use all the resources contained in the these wireless networks. Because the characteristics of wireless devices that are difficult to physically secured so security can only be done by using policies or use a computer program that usually provided by vendors such wireless device makers with only perform simple settings and easy.
