Can I trust the Windows XP SP2 firewall to protected a machine with a direct Internet connection? I usually use a broadband router to protect my machines, but I still keep their own personal firewalls activated. But due to various issues, I sometimes find it necessary to disconnect the router and to connect one machine directly to the broadband modem.
Prior to SP2, I had been using ZoneAlarm and Sygate, but once SP2 came out, I figured the Windows Firewall should be at least as capable at basic protection as the other two. I also used to notice that there were regular updates to ZoneAlarm, which I figured were them plugging up newly discovered security holes in their software. However, barely any updates to Windows Firewall.
Does anyone know if there's any vulnerability that's been discovered that will allow a hacker to blow past the Windows Firewall?
