Service Name: Firewall / Network Access Control Change Requests


Description:

Computing and Communications (C&C) operates perimeter (Internet/CA*net4) and select internal firewall services on behalf of main campus St John's.

What's included:

So as to best protect the confidentiality,
integrity, and availability of main campus IT resources, these resources are by
default not accessible from off campus. Units seeking exceptions to this
implicit deny perimeter firewall policy should contact the C&C’s Service
Desk.

An assessment of the requested access will be conducted by Computing and Communications staff as per Service Catalog entry VULNERABILITY
ASSESSMENTS
. Provided the proposed change is found to pose no risk to the wider internal community, the requested firewall exception will be made. Otherwise, Computing and Communications will advise the requestor as to what patches, reconfiguration, or other improvements are first needed to secure the service before extending external access.

Client departments running extremely sensitive services may wish (or be
required) to firewall their services not just against Internet/C4 access, but against other networks internally. Clients who feel they may have such services should contact Computing and Communications through Service Catalog entry SECURITY CONSULTING REQUESTS.

Clients needing adjustment of internal firewall mechanisms already in place should contact the Service Desk below.
