Built-in Personal Firewall (Windows)
Important Note: Some Schools and Centers manage firewalls via their own network servers. Faculty and staff should speak with their Local Support Provider (LSP) to determine if and how their firewall is being managed.
The built-in personal firewall in Microsoft Windows 7, Windows Vista, and Windows XP helps to protect your PC from some network attacks. The firewall provides an added level of protection against malicious activity by examining and restricting network traffic to your computer. Information Systems & Computing (ISC) recommends using the built-in firewall in conjunction with other good security practices such as promptly applying Windows security patches and setting the current version of Symantec Endpoint Protection for regular, automatic updates.
The Windows 7, Windows Vista, and Windows XP built-in personal firewalls are commonly used with few issues at the University. If you need assistance activating your firewall or if you encounter problems with your firewall, please consult with your local support provider (LSP) as a first step. You can also refer to Microsoft's advice for manually opening ports.

The built-in firewall in Windows Vista resembles the one in Windows XP Service Pack 2, with some added capabilities.
