Policy: Azure > Network > Network Security Group > Ingress Rules > Approved > Prohibited Ports

A YAML list of ports that are prohibited and may not be used for ingress in custom security groups. For example, 21 might be prohibited to prevent the use of FTP. This list is also applied to ICMP rules, so should be checked against valid ICMP numbers.

Applies to non-Guardrails managed Security Groups.

Examples: - 21 # FTP - 25 # SMTP
