Ensure security groups restrict outbound traffic
Security groups should restrict outbound traffic to only required destinations and ports, implementing egress filtering.
Security Impact
Unrestricted outbound access allows compromised instances to communicate with command-and-control servers or exfiltrate data.
How to Remediate
Remove the default allow-all outbound rule and add specific rules for required outbound traffic.
