8 Steps to Secure Your Computer
There are simple steps you can take to make your computer safer. Any computer connected to the network is vulnerable to attack, but by following the steps below you can minimize your risk.
Required
- Safely install the Windows Operating System
If you use Microsoft Windows, follow the guidelines from OIT to safely install the operating system so you don't get infected with a virus. If you use a Macintosh or Linux computer, start with step 2. - Update Your Operating System
Most security issues are related to vulnerabilities in the operating system. As these flaws are discovered software companies release patches and updates to protect you from the security holes. - Install and Update Anti-Virus Software
One of the largest risks to a network is an infected or compromised computer. An infected computer can spread a virus quickly to other computers over the network. Anti-virus software is critical to practice safe computing. - Use Strong
Passwords
By default modern operating systems are accessible remotely. If you have not set a strong administrative password or left it blank, this makes your computer vulnerable to various types of attacks, including "dictionary attacks" which is a rapid, automated guessing of common passwords.
Strongly Recommended
- Enable Firewall Protection
Firewall software can help protect your computer against hackers and other security attacks. Severe attacks can delete important information, crash your system, or steal private information like passwords or credit card numbers. Windows XP, Mac OS X (v. 10.2 or later), and Linux have built in firewalls. - Install and Use Spyware Removal
Tools
Spyware is software that is downloaded and installed onto your computer, often without your knowledge. Spyware monitors and shares your information while you browse the Internet. - Back Up Important Files
No system is completely secure. If you have important files stored on your computer, copy them to another removable drive or disc and store them in a different location from your computer. - Enable Screen Saver Passwords
When you are away from your computer, lock the screen or set a screen saver password. This will prevent someone from using your computer when you are away from your desk.
