Windows XP Service Pack2 within the SCS Environment
Windows XP SP2 contains many security enhancements. The most significant of these is the Windows firewall, which is turned on by default and is the officially supported firewall in SCS Computing Facilities. Our staff has assembled a set of firewall rules that will be applied to machines that are members of the SCS Active Directory Domain via Group Policy to ensure that the standard desktop applications and commonly used Internet Services continue to function (Http,FTP,SSH,etc.).
Note that file sharing, instant messaging and programs that listen for connections but are not part of the standard environment ARE NOT included in the global firewall configuration. These programs/ports will need to be added to the firewall configuration by the end user. Also, computers which ARE NOT located within any of the SCS Computing Facilities managed buildings may need to add firewall exceptions to allow communication between hosts. The buildings currently managed by SCS Computing Facilities are as follows:
407 South Craig
If you are installing SP2 on a standalone host that is not a member of the SCS Domain, or if you have installed/written additional programs that listen for incoming traffic, you will likely need to perform some additional firewall configuration.
Popup Blocker and enhanced security in Internet Explorer
SP2 will install a pop up blocker and increase security within Internet Explorer.
