Learn AKS network security
For an AKS cluster, there are two sorts of site visitors. First one is the interior site visitors between pods. The second is the ingress and egress site visitors that’s between pods and the top customers or the web.
This course supplies the instruments and strategies to safe these networks utilizing instruments like Network Insurance policies with Calico, TLS certificates, and so on.
Microsoft supplies the next suggestions to safe an AKS cluster and this course will attempt to go deeper with demonstration.
Suggestion 1: To distribute HTTP or HTTPS site visitors to your purposes, use ingress sources and controllers. In comparison with an Azure load balancer, ingress controllers present additional options and will be managed as native Kubernetes sources.
Suggestion 2: To scan incoming site visitors for potential assaults, use an internet utility firewall (WAF) equivalent to Barracuda WAF for Azure or Azure Software Gateway. These extra superior network sources may also route site visitors past simply HTTP and HTTPS connections or primary TLS termination.
Suggestion 3: Use network insurance policies to permit or deny site visitors to pods. By default, all site visitors is allowed between pods inside a cluster. For improved security, outline guidelines that restrict pod communication.
Suggestion 4: Do not expose distant connectivity to your AKS nodes. Create a bastion host, or soar field, in a administration digital network. Use the bastion host to securely route site visitors into your AKS cluster to distant administration duties.
