Ensure default VPC is not used

The default VPC in each region should not be used for workloads. Default VPCs have overly permissive default security group and subnet configurations.

Security Impact

Default VPCs have public subnets with auto-assigned public IPs, increasing exposure of resources.

How to Remediate

Create custom VPCs with appropriate CIDR ranges and security configurations. Delete or restrict access to default VPCs.
