Computer Security Recommendations


Many new computers ship with very poor default security, which can become hazardous when they are connected to the Internet. This page is intended to provide you with some basic steps you can take to increase the security of your laptop.
No single product can provide total security; different tools stop different threats. If you implement the suggestions below to add multiple layers of security, your machine will be a lot more difficult to compromise.



Keep your operating system up to date
Don't undermine your computer's protection by providing hackers "back doors" to your computer. Updating your operating system (and your applications such as Microsoft Office and Adobe Flash) plugs security holes that hackers are constantly seeking. Check for Microsoft Updates or Apple Software updates at least once a week to keep your computer up-to-date with security and other bug patches. Do a check as "close to immediately" as possible after connecting to the Internet. Both Windows Update and Apple's Software update are turned on by default.  Instructions for how to check if you are receiving updates automatically are below:

Mac OSX 10.6+
Windows: Click the Start button and type Windows Update.  Press Enter.

Anti-virus Notes for Windows

Law IT strongly recommends that you have some kind of anti-virus program on your computer that is up-to-date. Many PCs come with trial versions of anti-virus software, but they usually expire after a couple of months forcing you to purchase a full version in order to keep up to date with the latest malware threats. Rather than pay for these types of subscriptions, the University recommends downloading and installing Microsoft Security Essentials (MSE) for Windows 7. MSE is free for personal use to all genuine Windows users. If you have Windows 8, 8.1, or 10 Windows Defender (the equivalent to Security Essentials) should be installed and enabled by default. You should check to make sure it's running properly. 

  1. Make sure that if you have an anti-virus program already installed you remove it and restart your computer before installing any new anti-virus software.



Other Important Security Tips for Windows
  1. Make sure your computer is set to receive Windows Updates and has a Firewall program enabled. To check:
        Windows 7      Windows 8, 8.1      Windows 10

  2. Keep other programs up to date. Many malware attacks prey on computers with outdated versions of popular programs such as Adobe Flash, Adobe Reader, and Java.   To better protect yourself against these threats, update these programs when you are prompted to do so.

  3. Sign up for two factor authentication. Two-factor authentication is an added security layer for protected resources. The Law School strongly recommends turning on two-factor authentication for all weblogin-protected resources.

Anti-virus Notes for Mac
The University supports Sophos Anti-Virus, which is available at no cost.
  1. Make sure that if you have an anti-virus program already installed you remove it and restart your computer before installing any new anti-virus program.
  2. Make sure to check the date on your anti-virus program often. One sign that your computer may be infected is that your anti-virus program stops updating properly.


How to check the date for Sophos Anti-Virus:

Click the 'S' shield icon in the menu bar, then click the About button.
Make sure Sophos states that it is up to date.

    NOTE: You may need to click the lock icon Lock Icon at the bottom of the window and authenticate first to make this change.

    • Under the General tab, uncheck Open "safe" files after downloading.

     uncheck this setting

Backups are Critical
Part of good security is keeping backups of your important files; multiple backups to flash drive, Cloud storage, etc. Backups are inexpensive. Data recovery, on the other hand, is very expensive, and sometimes not possible. Make backups often and check the backups to make sure that they are reliable.
