AS-ACS Windows-Ring1 Template Rules
Attention Application Owners & Rule Delegates
The following set of firewall policies, referred to as "Template Rules", are provided for administrators of AS owned/managed 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.
