Stay on top of the latest in cyber security Be the first to know about SSH. Depending on the system, you may also need to start the server if you don't want to reboot. The following should work on most systems:. SSH is often used with public key authentication to implement automation and single sign-on.
Public key authentication uses a new kind of access credential, the SSH key , for authentication. It is much more secure than traditional password authentication, especially compared to hard-coded passwords in scripts, but the keys need proper management.
Most organizations with more than a hundred servers have large numbers of SSH keys. Usually, these keys have not been properly managed and audited. An SSH risk assessment is recommended. Organizations should consider deploying key management software to establish proper provisioning, termination, and monitoring for key-based access.
Risks of unmanaged SSH keys include uncontrolled attack spread across the server infrstructure, including to disaster recovery data centers and backup systems. Organizations should also be aware of security risks related to SSH port forwarding. It is a technology that has many good uses, but it can also enable unfettered access across firewalls.
Employees and attackers can leave tunnels back into the internal network from the public Internet. This particularly affects organizations using cloud computing services. Telnet is insecure. Its use is not recommended.
