Other Security Tips
Update Other Software
Security vulnerabilities can exist in all software. Keep your software updated. You will find update information, for most software packages, from the Help menu.
Secure the Safari Web Browser
The Safari web browser, by default, is configured to automatically open safe files after downloading. This feature can be used by malicious attackers to compromise your Mac when you visit a web site.
Use the steps in the Configuring Safari 2.0 section of the Configuring your Web Browser document to disable automatic opening of safe files. You can open the files yourself by double-clicking on them after download.
Virtual PC Security
If you use Virtual PC to run Microsoft Windows on your Mac and connect to the network, secure your computer like any other Windows machine. Refer to the Securing Your Windows Computer document for details.
Use Encrypted Authentication
Clear-text transmission methods transfer your user ID and password WITHOUT converting them to an encrypted form. This makes your user ID and password readable by outsiders who may attempt to intercept and use the information.
Carnegie Mellon servers DO NOT allow clear-text authentication. To ensure normal email and server access, follow the steps in the Using Encrypted Authentication Methods document.
Backup Your Data Periodically
You should perform regular backups on a weekly basis. At a minimum, backup your data before and after any system or data changes. Recovering from a system crash or a security compromise can be expedited if you maintain proper backups. Otherwise, you may be without your system for days or weeks and recreating lost work can be extremely difficult. For more information, read the Establish a Backup Routine section of the Security: General Practices document.
IMPORTANT NOTE: Secure your backup media in a safe, locked place. It may contain sensitive information.
