Organizations who recognize the risks posed by SSH Key sprawl risk and take a proactive cybersecurity posture, typically use a dedicated SSH key management or automated privileged password management (PPM) solution to generate unique key pairs for each system, and perform frequent rotation. SSH user folder, but this falls short of helping you identify who has the private key matching any of the public keys in the file. For instance, you could identify accounts set up to use SSH keys, you could manually scan through authorized keys file in the hidden. In even modestly complex environments, manual SSH Key rotation is infeasible. The NIST recommendations emphasize SSH key discovery, rotation, usage, and monitoring. NIST IR 7966 offers guidance for government organizations, businesses, and auditors on proper security controls for SSH implementations. As with any other security protocols, it’s imperative to maintain strong standards and best practice around SSH network protocols and keys.
