ITS CRC Server Group Template Rules

Attention Application Owners & Rule Delegates

The following set of firewall policies, referred to as "Template Rules", are provided for administrators of Windows based servers that require a specific set of source hosts/nets and services allowed for administration.

When applying these Template rules, please consider any additional necessary "custom" policies to guarantee the inbound or outbound connectivity that servers will require. Those "custom" policy requests can be made via the Firewall Rule Request form.

Please contact the Firewall Team (firewall-team@lists.stanford.edu) with any questions.
