Security Improvements for EKS Cluster

[CodemasterDevops421]

Security Improvements Needed

Current Issues:

1. Default VPC and EKS configurations may not follow security best practices
2. Network policies might need to be reviewed and tightened
3. Potential for improved pod security policies

Proposed Changes:

1. Implement Network Policies:

   • Restrict pod-to-pod communication
   • Define ingress/egress rules
   • Set up namespace isolation

2. Enhanced Security Groups:

   • Review and update security group rules
   • Implement principle of least privilege
   • Document all allowed ports and services

3. Pod Security Policies:

   • Implement PSPs to restrict pod privileges
   • Set up container runtime security
   • Define resource quotas and limits

4. Authentication and Authorization:

   • Review IAM roles and permissions
   • Implement RBAC policies
   • Set up proper service accounts

Implementation Plan:

1. Create necessary security policies
2. Test in staging environment
3. Document all changes
4. Implement monitoring for security events
