How do I protect my computing devices (#4465)
Ever wonder how you can better protect yourself from cybercriminals? The following section provides tips and tricks on how to protect your computers and other computing devices from viruses, thefts, and other threats.
General Best Practice
There are a few general tips for all computer users, whether you are using PCs, Macs, or other platforms.
- Always use a long password or passphrase
Longer passwords are always more secure. For example, "I wuv ch33se pizza!" is a better password than "B7%gdA11?s", and it is also easier to remember!
- Use Antivirus on your computer
Regardless of the computer that you use; Antivirus is one of your best defenses against viruses and malware. VCU has a list of free Antivirus software that it recommends for faculty, staff, and students!
- Use Antispyware / Antimalware software
In addition to using Antivirus, you can also run antispyware and antimalware software periodically. While this software may not provide you with the real-time protection like an Antivirus software, they can catch certain malware or virus that the antivirus software may have missed. A good Antimalware software is Malwarebytes Anti-Malware.
- Update your Operating System
Regardless of the computer you are using; you must make sure that the Operating System (Windows, Mac OS, Ubuntu, etc.) is up-to-date. Most operating systems offer easy and sometimes automated ways to patch security vulnerabilities.
- Update your applications
Applications like Adobe Acrobat, Flash, Java, and Apple iTunes, Quicktime are prime targets for attackers. It is imperative to check your applications and ensure that they are properly patched. VCU offers LANDesk for the automatic patching of selected applications on VCU workstations and laptops. Qualys Browsercheck can also be used periodically to check for out of date software and plug-ins on your computer. Contact your IT support for additional information.
- Use Browser Advisor Software
Many viruses and malware infections can occur when you visit a malicious or infected website. In order to minimize the chance of catching an infection on a bad website and to be warned of a website's reputation before visiting the site, a browser advisor software may be used. Web of Trust is a great browser advisor, and it is free!
- Don't Leave Your Computer Unattended!
Thieves usually look for the crime of opportunity. Leaving your computer or other computing devices (phones, tablets, etc.) unattended in a publicly accessible area (unlocked office, cubicle, classroom, library, etc.) will increase the likelihood of your device being stolen. A cable lock can be used if a computer must be left in a publicly accessible area, or simply take your computer and devices with you when you leave an area.
- Lock your computer when you step away
If you work in an office environment with a stationary desktop or laptop computers, you may not want other people to be able to tamper with your computer programs and data when you step away from your desk. Locking a computer where password will be needed to regain access can be used to protect your computer from unauthorized access, especially when you don't have a locking door that can protect your computer. Locking a computer will allow programs to continue to operate in the background and cause no disruptions while effectively protecting your computer when you step away.
