NEW QUESTION # 26
You are deploying a highly sensitive application to a Kubernetes cluster. You need to configure CoreDNS to enforce strict access control and ensure that only authorized clients can perform DNS lookups.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Enable DNSSEC Validation:
- Configure CoreDNS to validate DNSSEC signatures to ensure that DNS responses are not tampered with.

2. Use Network Policies: - Implement network policies to restrict access to the CoreDNS service. Only authorized pods should be allowed to send DNS queries to CoreDNS.

3. Use RBAC for Access Control: - Implement Role-Based Access Control (RBAC) to restrict access to CoreDNS resources. Only authorized users or service accounts should be able to modify the CoreDNS configuration or access its logs.

4. Use Secure DNS: - Enable DNS over TLS (DOT) or DNS over HTTPS (DOH) to secure communication between pods and CoreDNS. This will prevent eavesdropping and data tampering.
