azure.networksecuritygroup

Network Security Group Resource

example:

This policy will deny access to all ports that are NOT 22, 23 or 24 for all Network Security Groups

policies:
 - name: close-inbound-except-22-24
   resource: azure.networksecuritygroup
   filters:
    - type: ingress
      exceptPorts: '22-24'
      match: 'any'
      access: 'Allow'
   actions:
    - type: close
      exceptPorts: '22-24'
      direction: 'Inbound'

example:

This policy will find all NSGs with port 80 opened and port 443 closed, then it will open port 443

policies:
  - name: close-egress-except-TCP
    resource: azure.networksecuritygroup
    filters:
     - type: ingress
       ports: '80'
       access: 'Allow'
     - type: ingress
       ports: '443'
       access: 'Deny'
    actions:
     - type: open
       ports: '443'

example:

This policy will find all NSGs with port 22 opened from ‘Any’ source

policies:
  - name: find-ingress-SSH-from-any-source
    resource: azure.networksecuritygroup
    filters:
     - type: ingress
       ports: '22'
       access: 'Allow'
       source: '*'

example:

This policy will find all NSGs with port 8080 enabled to ‘Any’ destination

policies:
  - name: find-egress-HTTP-to-any-destination
    resource: azure.networksecuritygroup
    filters:
     - type: egress
       ports: '8080'
       access: 'Allow'
       destination: '*'
