An unused AWS Security Group allows public access to the Secure Shell Protocol (SSH) port (22). SSH is used for administrative access to Linux/Unix operating systems and is an attractive target for attackers. Unused Security Groups should be removed, or if re-assigned, remove or restrict the inbound rule allowing SSH (port 22) in this Security Group.
