Use the following guidance to help secure your computers.

1. Updates and Patches

The simplest and best way to secure your computer is to configure the operating system to automatically check for updates:

5. Web Browsers

Firefox is the recommended web browser for Berkeley Lab. Refrain from using Internet Explorer (IE), especially older versions because of it's numerous vulnerabilities, for your general web browsing activities. Due to IE's market dominance, it is targeted for attack more so that any other browser distribution.

7. Passwords

Creating a good, strong password is not an easy task. The challenge lies in the making the password difficult to guess, but easy to remember. Using a different password for each account help protects you in the case where one account is compromised, the hacker will not be able to use that same password to compromise your other accounts.
