Ensure security groups do not allow ingress from 0.0.0.0/0 to port 22
Security groups should not allow SSH access (port 22) from the internet (0.0.0.0/0). Use bastion hosts, VPN, or AWS Systems Manager Session Manager.
Security Impact
Open SSH access allows brute force attacks and unauthorized access attempts from any IP address.
How to Remediate
Remove rules allowing 0.0.0.0/0 or ::/0 to port 22. Restrict access to specific IP ranges or use AWS Systems Manager Session Manager.
