Requesting a Change to the Network Firewall Ruleset

  1. Work with DoIT Support to collect the following information necessary for a change request:
    • Server Name
    • Type of Rule: Allow or Deny
    • Source and Destination IP addresses
    • Source and Destination Ports and Protocols
    • The reason why this change is needed
  2. Send a request to your manager requesting an exception to network firewall ruleset. If your manager approves the request, they should forward it to DoIT Support.
  3. DoIT Support will review the request and work with the Office of Cybersecurity to provide feedback if required
    • If DoIT Support has questions about the request it will be sent back to you. It can be resubmitted with modifications or appealed.
      • Appeals can be made through your director, who will work with DoIT Support and the Office of Cybersecurity to resolve the issue. If the issue cannot be resolved by your director and Cybersecurity, final authority rests with the CIO's Office.
  4. Once requests are approved, DoIT Support will fulfill the request and contact you with an update.

The Office of Cybersecurity will periodically review the firewall rulesets for need and appropriateness.
