What is Cyber-safety? | Top Seven Cyber-safety Actions | Viruses | Hackers | Spyware | Protect Passwords | Cyber-safety at Work

2012-10-10T18:12:00.000+05:30

What is Cyber-safety?

Cyber-safety is a common term used to describe a set of practices, measures and/or actions you can take to protect personal information and your computer from attacks.

At UC Davis, we have the Cyber-safety Program policy, PPM 310-22, (http://manuals.ucdavis.edu/ppm/310/310-22.htm)   which establishes that all devices connected to the UC Davis electronic communications network must meet certain security standards.

As part of this policy, all campus units provide annual reports demonstrating their level of compliance.

Further, there are services in place to help all students, faculty and staff meet the cyber-safety standards. Specific information about these services is provided in this tutorial.

Cyber-safety Threats

Viruses

Viruses infect computers through email attachments and file sharing. They delete files, attack other computers, and make your computer run slowly. One infected computer can cause problems for all computers on a network.

Hackers

Hackers are people who “trespass” into your computer from a remote location. They may use your computer to send spam or viruses, host a Web site, or do other activities that cause computer malfunctions.

Identity Thieves

People who obtain unauthorized access to your personal information, such as Social Security and financial account numbers. They then use this information to commit crimes such as fraud or theft.

Spyware

Spyware is software that “piggybacks” on programs you download, gathers information about your online habits, and transmits personal information without your knowledge. It may also cause a wide range of other computer malfunctions.

Top Seven Cyber-safety Actions

1. Install OS/Software Updates
2. Run Anti-virus Software
3. Prevent Identity Theft
4. Turn on Personal Firewalls
5. Avoid Spyware/Adware
6. Protect Passwords
7. Back up Important Files

Avoid Spyware/Adware

Spyware and adware take up memory and can slow down your computer or cause other problems.

Use Spybot and Ad-Aware to remove spyware/adware from your computer. UC Davis students, faculty and staff can get Spybot and Ad-Aware for free on the Internet Tools CD (available from IT Express in Shields Library).

Watch for allusions to spyware and adware in user agreements before installing free software programs.

Be wary of invitations to download software from unknown internet sources.

Protect Passwords

Do not share your passwords, and always make new passwords difficult to guess by avoiding dictionary words, and mixing letters, numbers and punctuation.

Do not use one of these common passwords or any variation of them: qwerty1, abc123, letmein, password1, iloveyou1, (yourname1), baseball1.

Change your passwords periodically.

When choosing a password:
Mix upper and lower case letters
Use a minimum of 8 characters
Use mnemonics to help you remember a difficult password

Store passwords in a safe place. Consider using KeePass Password Safe (http://keepass.info/), Keychain (Mac) or an encrypted USB drive to store passwords. Avoid keeping passwords on a Post-it under your keyboard, on your monitor or in a drawer near your computer!

Cyber-safety at Home

Physically secure your computer by using security cables and locking doors and windows in the dorms and off-campus housing.

Avoid leaving your laptop unsupervised and in plain view in the library or coffee house, or in your car, dorm room or home.

Set up a user account and password to prevent unauthorized access to your computer files.

Do not install unnecessary programs on your computer.

Microsoft users can download the free Secunia Personal Software Inspector (https://psi.secunia.com/), which lets you scan your computer for any missing operating system or software patches and provides instructions for getting all the latest updates.

Cyber-safety at Work

Be sure to work with your technical support coordinator before implementing new cyber-safety measures.

Talk with your technical support coordinator about what cyber-safety measures are in place in your department.

Report to your supervisor any cyber-safety policy violations, security flaws/weaknesses you discover or any suspicious activity by unauthorized individuals in your work area.

Physically secure your computer by using security cables and locking building/office doors and windows.

Do not install unnecessary programs on your work computer.

What is a computer virus?

A computer virus is a malicious program that spreads from computer to computer.

Viruses, Worms, Trojan Horses

Have you heard other names for malicious computer programs?
Viruses, Worms, Trojan Horses
There are technical differences between each of these, but all of them attempt to run on your computer without your knowledge.

Malware

The most general name for a malicious computer program is malware.
You may have heard computer programs called software.
The word malware comes from MALicious softWARE.

How does malware invade your computer?

You have probably heard of some ways that malware can invade your computer.
What are they?
Through email attachments
By clicking on a web link when surfing the web
By downloading a program that claims to be a game or cool picture
Others?

Front Door Attacks

What do many of these attacks (through email, web browsing or downloads) have in common?
They all require the actions of a legitimate user.
They can be considered “front door” attacks because a user is tricked into opening the door for the attack through their action.

Understanding Front Door Attacks

The key to understanding front door attacks is that when you run a program it runs with *all* your rights and privileges.
If you can delete one file, any program you run can delete all your files.
If you can send one email, any program you run could send thousands of spam emails.
This includes any program you run even accidentally by opening an email attachment or clicking on web link.

Back Door Attacks

Not all attacks require action by a legitimate user.
“Back door” attacks target vulnerabilities in server software that is running on your computer.
Server software is software that listens for requests that arrive over the network and attempts to satisfy these requests.
A web server is an example of server software.

Are you running any servers?

Most home computer users think they are not running any server software.
However you would be surprised.
For example, most default installations of Windows run a number of network services by default.

How can you check?

At a Windows command prompt, type the command “netstat –an”.
It will display a list of server software that is listening for requests over the network.

What do viruses do?

Once an attacker manages to exploit a weakness, they can run any code they want on the victim’s machine.
Attack codes vary in what they try to do.
Have you ever suffered a computer attack? What happened to your machine? How hard was it to recover?

What does malware do?

Some attackers just want to see if they can make an attack succeed.
The malware they write may simply displaying something to the user or announce its presence in another way.
Other attackers want to do damage to others without trying to benefit directly.
The malware they write might delete files or otherwise corrupt the system.
Still others try to write malware that steals information from the victim.
The malware they write might search for credit card numbers or other personal information and send it back to the attacker.
Spyware might watch for victim’s passwords or otherwise spy on their online activity.

Blackhat vs Whitehat

Blackhat computer hackers look for flaws in software to exploit them or break into computer for malicious purposes.
Whitehat computer hackers look for flaws in software to fix them or attempt to break into computers to audit their security.

What do whitehat hackers do?

Analyze server software for flaws that could be exploited and recommend fixes.
Analyze new viruses or malware to characterize what they are doing and to build patches.
Audit the overall security of computer systems.

What is a virus?

A virus is a program that self-replicates
It is not data
You can only catch a virus by running a program
Your computer runs all kinds of programs

Basic virus terminology

Virus
Self-replicating
Also called a worm
Trojan Horse
A program which appears to be valuable but has an unexpected consequence

How viruses get into computers

The four most common virus infections come from:
File – A virus type that infects existing files on the computer (~40%)
Macro – A virus that runs as a macro in a host application such as the MS Office applications (~35%)
VBScript – A virus that uses Windows VisualBasic Script functionality (~10%)
Internet Worm – A virus that is primarily characterized by it’s replication across the Internet (~5%)

The impact of viruses

ICSA Labs estimates that the cost of a virus disaster is between $50,000 and $500,000
Average server downtime for a virus is 14 hours

Basic virus defense

Don’t open files that you are not expecting
Many viruses automatically send files without the e-mail account owner’s knowledge.
Ask the sender to confirm unexpected files.
Suspect messages that appear more than once in your Inbox
You may receive the same e-mail from a virus repeatedly.
Learn file extensions
Your computer will display both an icon and a file extension for files you receive. Open only file extensions you know are safe.
When in doubt, call the help desk.

Examples of risky file types

The following file types should never be opened:

.EXE
.PIF
.BAT
.VBS
.COM

Office protection

Office files are mostly data with some program code
Office macros are programs, which can be viruses
Office will prompt you to enable macros
Enable macros only when you know why office is asking

Outlook file security

Outlook will automatically block some kinds of executable files, but not all
If you need a file that Outlook blocked, call the help desk
Do not assume that because the file made it through Outlook that it is safe

Anti-virus warnings

Notify the help desk when you receive a virus warning from Norton Antivirus, Symantec Antivirus, Trend Micro, etc.
Most of the time, the virus software will detect and prevent the infection. However, the help desk can better tell you what to do.

Strong Authentication

Avoid disclosure of passwords on the network
No network services (logon or read/write ftp) visible on the general internet can be offered with out requiring Kerberos authentication (unless a formal exemption is applied for and granted)
Kerberos provides a single sign in, minimizing use of multiple passwords for different systems
Lab systems are constantly scanned for violations of this policy

Critical Systems

Defined as “critical to the mission of the Laboratory”, i.e. disruption may have major impact on Laboratory operations;
Most things do not fall in this category;
Special (more stringent) rules & procedures apply;
Including periodic reviews;
You’ll know if you’re in this category;

Critical Vulnerabilities and Vulnerability Scanning

Certain security vulnerabilities are declared critical when they are (or are about to) being actively exploited and represent a clear and present danger
Upon notification of a critical vulnerability, systems must be patched by a given date or they will be blocked from network access

IDE connectors are often keyed, as to prevent inserting them backwards. It does not take much force to bypass this and possibly ruin your motherboard. Look carefully at the drive and the cable connection before you try to connect them. You should see a "missing" pin on the drive, and a corresponding blocked socket on the connector. If you break a pin on the drive, you will probably have a worthless drive.

Most parallel IDE cables have a colored stripe down one side. That colored stripe signifies "pin 1" - and usually will line up next to the Molex power connection on your drive. Use this rule of thumb if your connectors are not keyed.

How a drive is physically installed will depend on the case.

A Serial ATA connector

Floppy Disk Drive Cable

Most new drives are SATA (Serial ATA) which use simple, small cables for a data connection. The ends of the cables are L shaped, just look carefully at the cable ends and the connector on the drive and match them up. Only one drive can be connected to each SATA port on the motherboard. Some SATA drives have two different power ports - make sure you connect ONLY ONE of these ports to the power supply, connecting both can damage the drive.

Older drives have PATA (Parallel ATA) connections which use a flat ribbon (IDE) cable for data connection. When using an IDE cable, plug the two connectors that are closer together into the 2 drives, and the third to the controller or motherboard. The connector furthest from the board should be attached to the drive set as Master. Make sure the drive that you will install your OS on is the primary master. This is the master drive on the Primary IDE bus which is usually the IDE 40 pin port on the motherboard labelled “Primary” or “IDE 1”..

Installing the CPU, and the CPU’s heat-sink and fan, are by far the most difficult steps you’ll have to complete during your build. Here, more than anywhere else, it will pay to read the instructions carefully, look at the parts, study the diagrams that came with your CPU and/or third party cooling solution, and make sure you thoroughly understand what you are going to do before you try to do it. During the process, if anything does not seem to fit or make sense, put the parts down and look things over carefully before you proceed. Some operations, especially installing the heat-sink/fan combination, can require pretty firm pressure, so don’t be afraid to push a little harder if you’re sure everything is set up correctly.

The details of the installation process differ in slight but important ways for each manufacturer’s processors, and even within a manufacturer's product line. Therefore, for these details, you should rely on the instructions that are provided with the CPU.

If you buy a third party cooling solution for your CPU make sure you get one that is compatible with the CPU you have. Most brands come with multiple mounting brackets that will suit many different chipsets, but it is best to check for compatibility just in case.

If using thermal paste, apply it only to the CPU die (the square piece of silicon in the middle of the CPU) and do so sparingly -- most modern CPUs take no more than a dab of thermal paste the size of a grain of rice. Some people do like to wipe some onto the heat-sink's surface and then wipe it smoothly off so that bits of it may get into tiny holes for better heat transfer.

One option you may consider, before installing the heat-sink, is to "lap" the heat-sink, which means to smooth out the bottom surface. To do this, you will need a very flat surface; a piece of thick window glass will work. Fasten your sandpaper on the flat surface, invert the heat-sink on the sandpaper and sand in small circles, applying minimum pressure. If you get it right, you should have a surface which feels completely smooth to the touch with a mirror finish. Some companies producing heat-sinks lap the surface themselves, so if the surface already looks like a perfect mirror, leave it alone. A lapped heat-sink is more effective as it will have better surface contact with the chip.

Tighten the cooler using only the specified holding devices - if you did everything right, they will fit. If they do not fit, check your setup - most likely something is wrong. After mounting the cooler, connect any power cables for the fan that is attached to the cooler.

If you have trouble lining up the screw holes, double check that you have the standoffs in the proper holes on the tray. With lower quality cases there are sometimes alignment problems and you may have to forgo one or two screws.

Remove the I/O Shield from the back of the case where the ports on the back of the motherboard will fit, and put in the I/O Shield that came with your motherboard. There may be small metal tabs on the inside of this face plate, if so you may have to adjust them to accommodate the ports on the back of the motherboard.

Some case styles make it difficult to install the motherboard or the CPU with the power supply installed. If the power supply is in your way, take it out and set it aside (we'll put it back in later).

Now locate the screw holes on your motherboard and find the corresponding holes on the motherboard plate (or tray) in the case. Put a standoff in each of these holes on the tray and position the motherboard so that you can see the holes in the top of the standoffs through the screw holes in the motherboard.

Now is the time to make sure the ports on the motherboard are mating with the back plate you just installed, and make any necessary adjustments. The small metal tabs are intended to make contact with the metal parts of the connections on the back of the motherboard and ground them, but you may have to bend these tabs a bit to get the ports all properly mounted, this is where those needle-nose pliers may come in handy.

KEYBOARD AND MOUSE SAFETY

Keyboard/Mouse

1)Ensure that the retractable legs on your keyboard are pulled back, allowing the keyboard to lay flat.

2)Use a keyboard with a wrist rest - these can also be purchased separately - these wrist rests really do work and greatly decrease fatigue and strain.

3)Your mouse should fit comfortably and naturally in your hand without any need to move any of your fingers to reach a button.

4)Ensure that the contacts inside your mouse are clean to allow for smooth use

5)Keyboards and mice should be regularly disinfected as they are a breeding ground for all sorts of bacteria.

6)Using the seating guidelines above, your keyboard should be the correct distance from you.

Tips

1)Your feet should not be dangling, but flat on the floor. If this is not possible, a footrest is recommended. Your knees should be slightly higher than your hips.
2)A chair with lumbar support is the optimum arrangement, if this is not available, back cushions can be obtained - even a rolled up towel can offer some support.
3)Your back should be firmly supported by the back rest.
4)Adjust the seat so that you can fit 3 fingers between the front of your seat and the back of your legs
5)When extending your arms to the keyboard, your wrists should be parallel with your elbow, this minimizes strain on the muscles of your arm.
6)The top of your monitor should be level with your eyes, or just slightly below eye level. The monitor should be approximately 50 - 70cm (19" - 27") from your eyes.
7)Rest your wrists and hands when you are not typing, don't keep them in a typing position while reviewing work etc.
8)Use document holders where possible. These should be placed at the same height beside the monitor and the same distance away as the monitor.
