Mac OS X Application Firewall
If you would like more information about Mac OS firewall settings, the Apple website also describes firewalls: http://support.apple.com/kb/ht1810
Mac users are advised to enable and configure the firewall software that is built into recent versions of the Mac OS, and to consider using a Web browser that offers good phishing protection.
Anti-virus products continue to be available. To have an anti-virus solution which is appropriate for your system installed on your university-owned Mac, visit the OIT Anti-virus page or contact OIT Support Services (Help Desk).
