Azure NSG exposure remediation for risky inbound rules.

Detection and remediation logic for overly permissive Azure NSG rules using source, port, priority, and rule intent checks.

Challenge

Not every broad rule has the same risk.

Azure NSG rules can become overly permissive when broad sources, dangerous ports, or low-priority allow rules expose resources to the internet. Remediation needs to understand intent so it does not break legitimate access patterns.

Approach

Evaluate rule context before action.

  • Checked source ranges for internet-wide exposure.
  • Evaluated destination ports and protocols against risky service patterns.
  • Reviewed rule priority and direction to understand effective access.
  • Allowed exception paths for approved business access.
  • Routed ambiguous rules for review instead of blind remediation.
Security Value

Exposure reduction with operational care.

The workflow demonstrates how cloud security automation can reduce internet exposure while preserving safety checks for ownership, exceptions, and service intent.
