In the ever-evolving landscape of IT security, traditional Privileged Access Management (PAM) solutions are facing new challenges, particularly in managing SSH keys. While most organizations have systems in place to manage passwords, TLS certificates, and accounts, SSH keys often remain overlooked. This oversight is significant, as SSH keys are critical access credentials that can outnumber passwords by a ratio of 10:1 in long-standing IT environments.
SSH keys present unique security challenges. They can act like skeleton keys, potentially granting access to multiple servers, and can be self-provisioned without central management. Moreover, SSH keys lack built-in identity association and expiration dates, making them easy to share or duplicate. The prevalence of automated connections using SSH further complicates the issue, with millions of machine-to-machine interactions occurring daily using these credentials.
Traditional PAM solutions struggle with SSH key management due to fundamental differences in how keys function compared to passwords. Most legacy PAMs were designed to vault passwords and attempt to apply the same approach to keys, which is ineffective. Proper SSH key management requires securing keys at the server side and addressing key configuration files, aspects that many traditional PAMs overlook.
The future of access management lies in credential-less access, particularly for dynamic environments using cloud servers, containers, or Kubernetes orchestration. Modern solutions offer ephemeral access, where secrets are granted just-in-time for a session and automatically expire after authentication. This approach eliminates the need to manage passwords or keys altogether, significantly reducing the attack surface, complexity, and associated risks. As organizations seek to future-proof their security infrastructure, the shift towards passwordless and keyless solutions is becoming increasingly crucial.
