Macintosh OS 8-9 Security Checklist

To immediately secure your Macintosh system, take the three steps below:

1. Install anti-virus software
   If you don't have anti-virus software installed, you may leave your system vulnerable to viruses, Trojan horses, spam, and other intrusions. Students, faculty and staff can download anti-virus software from the BevoWare site. You should configure your software to scan regularly and set your virus definition (DAT) files to auto-update.


2. Install a personal firewall
   A personal firewall protects your machine against Internet attacks and random network scans. Students, faculty and staff can download personal firewall software from the BevoWare site.


3. Run the software update application
   Keeping your software up-to-date helps protect your system. Macintosh provides a Software Update application that you can use to schedule regular automatic updates.

For increased security, you should also take the following steps:

Set strong passwords on all accounts
All users on the UT network are expected to choose strong passwords and guard them well. If someone else obtains your password, they can access your private data (including e-mail), alter or destroy your files and perform illegal or inappropriate activities in your name. To learn more about choosing strong passwords, visit the Password Dos and Don'ts topic.

Disable file sharing
File sharing should be disabled unless you are purposefully using it to copy items from one computer to another, or to allow a known party to access files stored on your computer.

Be careful when using peer-to-peer file sharing applications
Although peer-to-peer (P2P) applications such as Napster, Gnutella, iMesh, Audiogalaxy Satellite, and KaZaA, are a good way of sharing information, if you do not use them appropriately you may degrade the performance of the University’s network, unknowingly share your personal data, inadvertently violate federal copyright law, or expose your computer to malicious code or unacceptable use. Read What You Need to Know about Peer-to-Peer File-Sharing Applications.

Use secure file transfer
When transferring files over the Internet you should always use a secured connection. SSH and SFTP applications encrypt and protect your passwords and information. If you use Telnet or a non-secure FTP program, your information is sent in the clear for anyone to see. SSH and SFTP clients are available for download on the BevoWare site.
