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. The main problem with telnet is that it transmits all passwords and any transmitted data in the clear. Anyone with access to any computer on the same network can steal user names and passwords that are transmitted.
Such password sniffing attacks were very common on the Internet already in the s. Telnet sessions can also be hijacked in the network. Attackers can inject their own commands into telnet sessions.

Yet the SSH keys are access credentials, comparable to passwords, and grant often privileged access to resources. Management of SSH keys is a necessity for security and regulatory compliance alike. Even though they are critically important access credentials they are rarely under the control of corporate IT. They have traditionally been ignored in enterprise identity and access management and related policies.
It is clear that the situation cannot continue. It also reduces financial and reputation risks and helps ensure business continuity. Automating SSH key management can also save millions of dollars in operational costs annually in larger organizations. Together with our customers, our mission is to secure their digital business on on-premises, cloud, and hybrid ecosystems cost-efficiently, at scale, and without disruptions to their operations or business continuity.
