Redis attached subnet Network Security Group should allow ingress traffic only to ports 6379 or 6380

Deploying Redis Cache under a VNET provides enhanced security and isolation. Vnet also provides subnets, access control policies and additional networking and security capabilities. When using a VNET specific ingress and egress firewall rules are required. This feature is available to Premium tier Redis Cache only.

Risk Level: High
Cloud Entity: Azure Redis Cache
CloudGuard Rule ID: D9.AZU.NET.15
Covered by Spectral: Yes
Category: Database


RedisCache should have subnet.securityGroup.inboundSecurityRules contain-any [ destinationPortRanges contain [ destinationPort<=6379 and destinationPortTo>=6379 ] ] and subnet.securityGroup.inboundSecurityRules contain-any [  destinationPortRanges contain [ destinationPort<=6380 and destinationPortTo>=6380 ]  ]


From Portal
Pre-Requisite : VNET needs to be set up upon Redis Cache Launch.

  1. Go to 'Network Security Groups' from Azure Management console.
  2. For each Network Security Group that is attached to the concern Redis.
  3. Select Inbound security rules.
  4. Add a rule with Destination Port 6379 & 6380.
  5. Select Add.



Azure Redis Cache

Fully managed, open source���compatible in-memory data store to power fast, scalable application. Azure Redis Cache is based on the popular open-source Redis cache. It is typically used as a cache to improve the performance and scalability of systems that rely heavily on backend data-stores. Performance is improved by temporarily copying frequently accessed data to fast storage located close to the application. With Redis cache, this fast storage is located in-memory with Redis Cache instead of being loaded from disk by a dat
