&lt;div class=&quot;MsoBodyText&quot; style=&quot;text-align: justify; text-indent: 42.55pt;&quot;&gt;
&lt;span style=&quot;font-family: &#39;Times New Roman&#39;, serif; font-size: 14pt;&quot;&gt;Há &amp;nbsp;algumas semanas, vimos o anuncio oficial do uso
do IPv6 em alguns dos sites mais acessados do mundo. Isso é um exemplo de que o
uso de IPv6 está cada vez mais difundido e o cuidado com a segurança nessa nova
versão do protocolo IP é cada vez mais necessário. Segue algumas dicas iniciais de segurança para essa nova versão do protocolo IP.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoBodyText&quot; style=&quot;margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 35.35pt; margin-right: 0cm; margin-top: 0cm; mso-list: l0 level1 lfo1; tab-stops: 35.35pt; text-align: justify; text-indent: -14.15pt;&quot;&gt;
&lt;span style=&quot;font-family: Symbol; font-size: 14pt;&quot;&gt;·&lt;span style=&quot;font-family: &#39;Times New Roman&#39;; font-size: 7pt;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &#39;Times New Roman&#39;, serif; font-size: 14pt;&quot;&gt;Antes de mais
nada, devemos desabilitar o protocolo IPv6 em redes onde ele não está sendo
usado. O sistema de auto configuração e descoberta de vizinhança IPv6, pode ser
um ponto falho na segurança e além disso gera tráfego desnecessário na rede. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoBodyText&quot; style=&quot;margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 35.35pt; margin-right: 0cm; margin-top: 0cm; mso-list: l0 level1 lfo1; tab-stops: 35.35pt; text-align: justify; text-indent: -14.15pt;&quot;&gt;
&lt;span style=&quot;font-family: Symbol; font-size: 14pt;&quot;&gt;·&lt;span style=&quot;font-family: &#39;Times New Roman&#39;; font-size: 7pt;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &#39;Times New Roman&#39;, serif; font-size: 14pt;&quot;&gt;Em redes Microsoft, é de suma importância que seja desabilitado o tunelamento &quot;Teredo&quot;
que vêm habilitado por padrão nas versões&amp;nbsp; mais recentes do Windows. No
win7 basta desabilitar o serviço “&lt;b&gt;Auxiliar
de IP”:&lt;/b&gt; Fornece conectividade em túnel usando tecnologias de transição do
IPv6 (6to4, ISATAP, Port Proxy e Teredo) ISATAP, 6to4 e Teredo são habilitados
por default no Windows.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoBodyText&quot; style=&quot;margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 35.35pt; margin-right: 0cm; margin-top: 0cm; mso-list: l0 level1 lfo1; tab-stops: 35.35pt; text-align: justify; text-indent: -14.15pt;&quot;&gt;
&lt;span style=&quot;font-family: Symbol; font-size: 14pt;&quot;&gt;·&lt;span style=&quot;font-family: &#39;Times New Roman&#39;; font-size: 7pt;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &#39;Times New Roman&#39;, serif;&quot;&gt;&lt;span style=&quot;font-size: medium;&quot;&gt;Habilitar regras
IPv6 para os firewalls também é&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;font-size: 19px;&quot;&gt;indispensável&lt;/span&gt;&lt;span style=&quot;font-size: medium;&quot;&gt;&amp;nbsp;, lembramos que toda e qualquer regra de firewall IPv4
deve ser implementada também para IPv6, não há compatibilidade entre estas
regras... um exemplo disso é o uso do iptables onde um # IPTABLES –P &amp;nbsp;INPUT DROP apenas bloqueia pacotes da versão
4, para versão 6 usa-se #IP6TABLES -P &amp;nbsp;INPUT
DROP. um exemplo de script firewall ipv6 vemos neste link &lt;/span&gt;&lt;a href=&quot;http://bash.cyberciti.biz/firewall/centos-debian-rhel-ipv6-iptables&quot; style=&quot;font-size: 14pt;&quot;&gt;http://bash.cyberciti.biz/firewall/centos-debian-rhel-ipv6-iptables&lt;/a&gt;&lt;span style=&quot;font-size: medium;&quot;&gt;
. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoBodyText&quot; style=&quot;margin-left: 35.35pt; mso-list: l0 level1 lfo1; tab-stops: 35.35pt; text-align: justify; text-indent: -14.15pt;&quot;&gt;
&lt;span style=&quot;font-family: Symbol; font-size: 14pt;&quot;&gt;·&lt;span style=&quot;font-family: &#39;Times New Roman&#39;; font-size: 7pt;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &#39;Times New Roman&#39;, serif; font-size: 14pt;&quot;&gt;Outro fator
importante é que o uso do IPv6 coloca praticamente todos os hosts de sua rede
de frente para a internet, cabendo um maior cuidado com as configurações de
segurança. O NAT está perdendo força e caminha para a extinção... e com o surgimento
da internet das coisas,&amp;nbsp; será cada vez mais importante proteger o perímetro
não mais somente das empresas e governos.. mais de nossas próprias residências.&amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class=&quot;blogger-post-footer&quot;&gt;Credson Isaac

&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Nesta quinta feira 07/06 entrou oficialmente em vigor o IPv6. A passagem do padrão IP da versão 4 (IPv4) para a 6 (IPv6) ocorreu às 
00h01 GMT de quarta-feira (21h01 de Brasília na terça-feira), uma 
mudança imperceptível para os milhões de usuários conectados. &lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp; Os participantes no lançamento mundial do IPv6 incluem as quatro páginas 
mais visitadas do mundo - Google, Facebook, YouTube e Yahoo! - assim 
como os provedores de roteadores e serviços de internet em mais de 100 
países. Ao se somar o novo protocolo IPv6, estas companhias permitem a 
milhões de usuários finais desfrutar de suas vantagens sem terem que 
fazer nada&quot;, declarou a ISOC.&lt;/div&gt;&lt;div class=&quot;blogger-post-footer&quot;&gt;Credson Isaac

A Internet Society, da qual fazem parte Google, Yahoo!, Facebook e AT&amp;amp;T, entre outras gigantes, anunciaram nesta quarta-feira que o protocolo IPv6 começará a ser usado oficialmente em todo o mundo no dia 6 de junho deste ano. O novo sistema de direcionamento numérico dos usuários aos sites garantirá mais endereços online, uma vez que o sistema atual, o IPv4, tem hoje poucas opções ainda disponíveis.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;

Este é mais um argumento para os profissionais de Infraestrutura se atualizarem a respeito desta &quot;pilha&quot; de conhecimento. E é com esse objetivo que estarei retomando a serie de publicações relacionadas ao IPv6.&lt;br /&gt;

A atuação do &lt;b&gt;PTTMetro&lt;/b&gt; volta-se às regiões metropolitanas no País que apresentam grande interesse de troca de tráfego Internet. &lt;br /&gt;
&lt;br /&gt;
Uma das principais vantagens deste modelo, é a racionalização dos custos, uma vez que os balanços de tráfego são resolvidos direta e localmente e não através de redes de terceiros, muitas vezes fisicamente distantes. &lt;br /&gt;
&lt;br /&gt;
Outra grande vantagem é o maior controle que uma rede pode ter com relação a entrega de seu tráfego o mais próximo possível do seu destino, o que em geral resulta em melhor desempenho e qualidade para seus clientes e operação mais eficiente da Internet como um todo. &lt;br /&gt;
&lt;br /&gt;
Um &lt;b&gt;PTTMetro&lt;/b&gt; é, assim, uma interligação em área metropolitana de pontos de interconexão de redes (PIXes), comerciais e acadêmicos, sob uma gerência centralizada. &lt;br /&gt;

Dentre essas ferramentas, fiz um breve comparativo entre as 3&amp;nbsp; das mais utilizadas na atualidade, o PRTG, ZABBIX, NAGIOS.&lt;/span&gt;&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot; style=&quot;line-height: normal; margin: 0cm 0cm 0pt; text-align: justify; text-indent: 42.55pt;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;,&amp;quot;serif&amp;quot;; font-size: 12pt;&quot;&gt;Essas 3 ferramentas utilizam diversas maneiras de obterem informações dos ativos &amp;nbsp;gerenciados ou sobre sua tutela. O protocolo SNMP (do inglês &lt;b&gt;Simple Network Management Protocol&lt;/b&gt; - Protocolo Simples de Gerência de Rede) é o mais usado&amp;nbsp;na maioria&amp;nbsp;das ferramentas disponíveis. Para utilizar qualquer das 3 ferramentas supracitadas é recomendado sempre um cuidado maior com a segurança dos dados relacionados ao snmp. O ideal, é sempre que possível ocultar a comunidade publica do snnp e utilizar-se de comunidades privadas com senhas de acesso para seus dados trafegarem de maneira segura na rede.&lt;/span&gt;&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot; style=&quot;line-height: normal; margin: 0cm 0cm 0pt; text-align: justify;&quot;&gt;&lt;br /&gt;

Apesar de ser um software proprietário, possui sua versão free, onde suas&amp;nbsp;ferramentas são limitadas, porém na versão full, é uma boa ferramenta, suporta diferentes tipos de equipamentos, fornecendo&amp;nbsp;análise aprofundada e concisa em relatórios. O PRTG oferece cinco diferentes interfaces de gerenciamento sendo 2&amp;nbsp;web&#39;s, 1&amp;nbsp;para plataforma windows, 1 para o Android, e uma para o IOS, fechando assim uma boa gama de dispositivos moveis.&amp;nbsp;É ótimo para que precisa de um gerenciamento e que não tem um bom nível de conhecimento.&lt;/span&gt;&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot; style=&quot;line-height: normal; margin: 0cm 0cm 0pt; text-align: justify;&quot;&gt;&lt;br /&gt;

O zabbix é baseado em PHP-APACHE e utiliza banco Mysql ou Postegree. Existe boa documentação em português porem as veções não estaveis possuem uma morosidade em suas traduções. Sua pagina oficial é : &lt;i&gt;&lt;a href=&quot;http://www.zabbix.org/&quot;&gt;&lt;span style=&quot;color: blue;&quot;&gt;http://www.&lt;b&gt;zabbix&lt;/b&gt;.org&lt;/span&gt;&lt;/a&gt;&amp;nbsp;.&lt;/i&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot; style=&quot;line-height: normal; margin: 0cm 0cm 0pt; text-align: justify; text-indent: 42.55pt;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;Times New Roman&amp;quot;,&amp;quot;serif&amp;quot;; font-size: 12pt;&quot;&gt;Essse sistema,&lt;i&gt;&amp;nbsp;&lt;/i&gt;é ótimo para quem possui um bom conhecimento em linux e snmp, porém não precisa de uma ferramenta prática em sua configuração. O zabbix possui alertas em jamber, E-mail e scripts que podem ser customizados, um exemplo é utilizar modems 3G para o envio de SMS para seu celular, Seus mapas emitem sinais sonoros e visuais de acordo com a gravidade do evento.&lt;/span&gt;&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot; style=&quot;line-height: normal; margin: 0cm 0cm 0pt;&quot;&gt;&lt;br /&gt;

&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Quanto as fases de um sistema redundante varia de situação para situação...&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Sabemos que um estudo econômico, detalhado, da relação custo beneficio, deve ser o ponto de partida&amp;nbsp;para um projeto de redução de riscos..&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;A pergunta a ser feita é ...&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;O quanto eu deixo de produzir (lucrar)&amp;nbsp;quando o sistema se torna inativo por algumas horas ou minutos em minha corporação...&amp;nbsp;&amp;nbsp;?&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;O quão estamos dispostos a investir para que isso não ocorra....?&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Com estas repostas podemos traçar o perfil de minha corporação e adequar o sistema a realidade apresentada.&lt;/div&gt;&lt;div class=&quot;MsoNormal&quot; style=&quot;margin: 0cm 0cm 10pt; text-align: justify;&quot;&gt;&lt;br /&gt;

Após o processo de privatizações das concessionárias de energia elétrica, tivemos substancial melhora nos serviços prestados..

&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Para a análise forense, a cópia bit-a-bit é de fundamental importância para a busca de evidências computacionais que venha a comprovar a inocência ou a culpa de um réu. Comumente ouvimos pessoas tecnicamente qualificadas explorando o comando &lt;b style=&quot;mso-bidi-font-weight: normal;&quot;&gt;dd&lt;/b&gt; como uma forma de realizar esta cópia. Mas será que um comando que roda em um sistema operacional tem a capacidade de descer a este nível de sinalização ?, &lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp;&lt;/span&gt;um pouco de arquitetura computacional mostra que para os dados serem disponibilizados pelo hardware para o S.O eles são alocados em unidades&amp;nbsp;chamadas de clusters ou blocos e seu tamanho varia de acordo com o sistema de arquivos&amp;nbsp;bem como&amp;nbsp;a capacidade total de armazenamento do HD , ou seja esse comando está mais para uma cópia bloco a bloco e não bit-a-bit. Para uma cópia bit-a-bit os fabricantes de duplicadores físicos garantem descer a esse nível&amp;nbsp;. Como o valor destes duplicadores físicos não está ao alcance da maioria dos peritos ou curiosos, o comando &lt;b style=&quot;mso-bidi-font-weight: normal;&quot;&gt;dd&lt;/b&gt; é realmente o que se aproxima mais do que realmente queremos.&lt;/div&gt;&lt;br /&gt;
Vejamos como o dd é usado..&lt;br /&gt;
&lt;br /&gt;
&lt;strong&gt;&lt;span lang=&quot;EN-US&quot; style=&quot;mso-ansi-language: EN-US;&quot;&gt;# dd if=/dev/hda1 of=/home/imagem.img&lt;/span&gt;&lt;/strong&gt;&lt;br /&gt;
&lt;br /&gt;
Para visualizar o processo use:&lt;br /&gt;
&lt;br /&gt;
&lt;strong&gt;# watch df -h&lt;/strong&gt; &lt;br /&gt;
&lt;br /&gt;
Sempre calcule o hash de sua imagem:&lt;br /&gt;
&lt;br /&gt;
&lt;strong&gt;# md5sum imagem&lt;/strong&gt;&lt;br /&gt;
&lt;strong&gt;&lt;/strong&gt;&lt;b&gt;&lt;br /&gt;

&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;O controle de banda vem sendo bastante utilizado na otimização do tráfego de downstream ( trafego de entrada ), bem como o upstream ( trafego de saída ), com isso a escolha de um serviço eficiente, deve levar em consideração o custo beneficio de tais aplicações.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;O CBQ, apesar de ser mais complexo de configurar , necessitando um grau maior de conhecimento em linux pelo fato da recopilação do kernel ser inevitável, produz melhores resultados no fluxo da informação em ambos os sentidos (up , down). Isso pode ser de fundamental importância quando temos que dimensionar links com diferentes taxas up-down, ex links ADSL.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Se esse é o seu caso essa é a solução.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;O HTB, bem mais simples de configurar, não contempla bons resultados para diferentes taxas up-down, porem atende as expectativas quando a palavra e link&#39;s síncronos com taxas up-down equivalentes. Se o seu link possui igual taxa de up-down, essa é a solução.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;

Durante o século XX, assistimos o surgimento e o crescimento da Internet com uma velocidade incrível. No ínicio da era comercial da grande rede de computadores, apenas pessoas que possuíam linha telefônica tinham acesso a rede mundial de computadores. Em seguida surgiram tecnologias como DSL, ADSL, ligações através de TV à Cabo e por rádio. O número de pessoas conectadas a rede cresceu de forma assustadora. No final da década de 90 surgiu uma tecnologia capaz de atingir ainda mais residências. Conhecida como PLC - Power Line Comunications - ou BPL - Broadband over Power Lines, permite o acesso a rede mundial de computadores através da utilização da rede elétrica já existente em mais de 95% do território brasileiro. Neste artigo, abordaremos um pouco do histórico dessa conexão, bem como sua arquitetura de funcionamento. Também discutiremos sobre suas vantagens e desvantagens comparadas a outros modos de conexão.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt; text-align: justify;&quot;&gt;2.Histórico:&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt; text-align: justify; text-indent: 35.25pt;&quot;&gt;Por volta de 1920 já era perceptível a iniciativa da utilização da fiação eléctrica para a transmissão de dados, com tecnologias remotas mas bastantes usuais como a transmissão de pulsos de telégrafos sobre redes trifásica. na época tornava-se inviável aprofundamento de tais pesquisas, mas com os avanços da microeletrônica e o barateamento de equipamentos voltou a ser um assunto interessante a se pensar, passando a se chamar PLC-Power Line Comunications. Uma das primeiras tentativas foi com o &quot;Riple Control&quot; onde seria utilizada no controle da iluminação pública. Com as atuais pesquisas pode-se chegar a uma taxa de transmissão por volta 45Mbps com utilização de 72 portadoras de alta freqüência simultaneamente.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt;&quot;&gt;2.1.PLC Brasil:&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt; text-align: justify; text-indent: 36pt;&quot;&gt;A CEMIG. veio com o primeiro investidor nessa tecnologia no Brasil onde visava utilizar a tecnologia x10 para a transmissão em horários de pico, para que fosse distribuída homogeneamente. A companhia também utilizava a tecnologia para leituras automáticas nos medidores de consumo onde um simples laptop poderia se conectar a um transformador onde nele onde nele conterias as leituras mensais do bairro inteiro.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt; text-align: justify; text-indent: 36pt;&quot;&gt;Outras companhias como a COPEL (PR), CELG (GO), Light (RJ), ELETROPAULO (SP) e EXCELSA fazem implementação de acesso à Internet via rede elétrica em residências para testes, mas pretendem disponibilizar ao público.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt;&quot;&gt;3. Funcionamento básico:&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt; text-align: justify; text-indent: 36.75pt;&quot;&gt;O princípio do funcionamento da BPL é que como a freqüência do sinal de conexão é na faixa dos MHz (91,7 a 30) e a energia elétrica é da ordem dos Hz (50 a 60 Hz) os dois sinais podem conviver tranqüilamente no mesmo meio. O sinal BPL é enviado pela central para um equipamento chamado INJETOR BPL, que se encarrega de inserir o sinal da Internet da rede elétrica. O sinal chega a outro equipamento chamado REPETIDOR BPL cuja função é não deixar que o sinal de Internet não seja atenuado. Quando o sinal chegar ao EXTRATOR BPL é convertido para ser usado pelo computador do usuário final. Vale informar que a velocidade do PLC possui velocidade não assíncrona. Isso significa dizer que se tem o mesmo desempenho tanto no envio, quanto no recebimento de dados. Analisemos o esquema a seguir:&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt;&quot;&gt;&lt;b&gt;&lt;i&gt;&lt;span style=&quot;color: black; font-size: 10pt; line-height: 150%;&quot;&gt;QUADRO 1 -&amp;nbsp; Esquema de sinalização via rede elétrica.&lt;/span&gt;&lt;/i&gt;&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5haGoaRI-5GxDRwFJrpWb7Yws893QSm2l1FWsAGKYZ6q3KrNC-BqHINnT-BlWFBbE74sg-CejDVe79SFi5pSbJtS_12CwFrGAkXoYCQpg_4NXc34Na5OHERr4_K1Q5Rirc_M5gPWjyXI/s1600/3.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;65&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5haGoaRI-5GxDRwFJrpWb7Yws893QSm2l1FWsAGKYZ6q3KrNC-BqHINnT-BlWFBbE74sg-CejDVe79SFi5pSbJtS_12CwFrGAkXoYCQpg_4NXc34Na5OHERr4_K1Q5Rirc_M5gPWjyXI/s320/3.jpg&quot; width=&quot;320&quot; /&gt;&lt;/a&gt;&lt;/div&gt;&lt;div align=&quot;center&quot; class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt; text-align: center;&quot;&gt;&lt;br /&gt;

Outro ponto positivo é a alta taxa de transmissão que pode alcançar 40Mbps atuando na freqüência de 1,7MHz a 30MHz. Uma característica importante da conexão na rede elétrica é o conceito de &lt;i&gt;grids inteligentes:&lt;/i&gt;eles têm a função de monitorar a extensão da fiação elétrica, permitindo reduzir as perdas na transmissão. Por exemplo, no caso da queima de um transformador, é possível saber exatamente em que ponto o problema ocorreu.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt;&quot;&gt;3.2.Desvantagens:&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-bottom: 14pt;&quot;&gt;Embora seja uma tecnologia promissora, a BPL também possui suas desvantagens:&amp;nbsp;&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-left: 36pt; text-align: justify; text-indent: -18pt;&quot;&gt;&lt;span style=&quot;font-family: Symbol;&quot;&gt;·&lt;span style=&quot;font: 7pt &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;O sinal acaba atenuando (enfraquecendo) após percorrer distâncias muito longas.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-left: 36pt; text-align: justify; text-indent: -18pt;&quot;&gt;&lt;span style=&quot;font-family: Symbol;&quot;&gt;·&lt;span style=&quot;font: 7pt &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;A freqüência utilizada pelo sinal pode interferir em alguns equipamentos eletro-eletrônicos; de forma idêntica, outros aparelhos podem interferir na transmissão&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-left: 36pt; text-align: justify; text-indent: -18pt;&quot;&gt;&lt;span style=&quot;font-family: Symbol;&quot;&gt;·&lt;span style=&quot;font: 7pt &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;A necessidade de instalação de repetidores em cada transformador externo, pois filtram sinais de alta freqüência&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-left: 36pt; text-align: justify; text-indent: -18pt;&quot;&gt;&lt;span style=&quot;font-family: Symbol;&quot;&gt;·&lt;span style=&quot;font: 7pt &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;A Impedância variável - Como a fiação das residências foram feitas para que o aparelhos e dispositivos funcionam em paralelo o ligamentos e desligamentos de tais equipamentos mudariam completamente a situação da rede de forma freqüente atenuando assim o sinal de transmissão.&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-left: 36pt; text-align: justify; text-indent: -18pt;&quot;&gt;&lt;span style=&quot;font-family: Symbol;&quot;&gt;·&lt;span style=&quot;font: 7pt &amp;quot;Times New Roman&amp;quot;;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;A Indutância elevada dos fios - os fios são livres de qualquer blindagem e também espesso e longos a indutâncias resultante em altas freqüências causam grandes atenuações nos sinais.&amp;nbsp;&lt;/div&gt;&lt;div class=&quot;Standard&quot; style=&quot;line-height: 150%; margin-left: 18pt; text-align: justify;&quot;&gt;&lt;br /&gt;

Tal evolução não está relacionada somente a área de comunicação, mas abrange todos os campos sociais como&amp;nbsp; educação, saúde e segurança alvos maiores dos governos e da população em geral.&lt;/span&gt;&lt;br /&gt;

O 802.11n veio com a &amp;nbsp;tecnologia MIMO usando múltiplos canais de transmissão e múltiplos canais de recepção para usufruir da comunicação em paralelo e assim ganhar com o almento de banda e o alcance das transmissões wifi. Quase que fazendo um mix das versões anteriores do protocolo wifi o 802.11n surge com taxas de transferências disponíveis: de 65 Mbps a 600 Mbps. -método de transmissão: MIMO-OFDM - Faixa de freqüência: 2,4&amp;nbsp;GHz e/ou 5&amp;nbsp;GHz e distancias de até ....&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Opa, falar de distâncias em&amp;nbsp; redes sem fio é de fato uma questão complicada, são muitas as variáveis de influência, dentre elas:&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;a) O ganho das antenas instaladas no ponto de acesso e no cliente&lt;br /&gt;
b) A potência dos transmissores&lt;br /&gt;
c) Os obstáculos e fontes de interferência presentes no ambiente&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Porém os fabricantes garantem 70m para ambientes fechados e 250 em ambientes abertos, más sabemos que com determinadas antenas podemos ampliar essa comunicação para a casa dos Km&#39;s.&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
&lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;Ofato é que o 802.11n no mínimo dobrou as taxas e distanciais do seu antecessor, o perigo é continuarmos a afirmar que o padrão wifi está chegando ao seu &lt;b&gt;&quot;limite físico&lt;/b&gt;&quot;.&amp;nbsp;&lt;/div&gt;&lt;br /&gt;

Estima-se que as empresas americanas gastarão entre 2 e 5 milhões de dólares para a adequação de seus controles internos a Sox.&amp;nbsp;Com isso aumentou ainda mais a necessidade de uma padronização e gerenciamento&amp;nbsp;dos processos referente a tecnologia da informação. Algum mecanismos de padronização surgirão e vem sendo aceito pela SOX, dentre eles os mais difundidos temos: ITIL (Information Technology Infrastructure Library) que lida com os processos referentes aos serviços de TI, COBIT para governança de TI e PMBOK é um conjunto de práticas em gestão de projetos de TI. &lt;/div&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;
