Exploring Windows Security, Action Center, and Firewall Settings
Windows XP Service Pack 2 (XP SP2) introduced Windows Firewall. This firewall, by most standards, lacked many controls and features found in most software firewalls; however, it was a firewall. As such, it was a leap forward in Windows security.
In addition to offering the firewall, XP SP2 unveiled the Security Center. This feature was designed as a consolidated security barometer reporting to the user the status of Windows updates, antivirus protection, and the firewall. The intent was that if any of these components needed attention, the user would be notified immediately. This feature survived through Windows Vista until being renamed the Action Center in Windows 7.
