🔑 What is SSH Key?

An SSH Key is a cryptographic key used to securely access remote machines. It consists of:

  • Public Key: Stored on the remote server
  • Private Key: Kept securely by the user

SSH stands for Secure Shell, enabling encrypted communication between machines.

🛠 What is SSH Key Management?

SSH Key Management is a centralized framework for governing all SSH keys in an enterprise. Key features include:

  • Centralized inventory of all SSH keys
  • Automated extraction of public keys from servers
  • Generation of security insights and compliance posture
  • Automated key rotation and deployment to servers
  • Prevention of unauthorized key usage

❗ Why is SSH Key Management needed?

Without SSH Key Management:

  • Keys must be tracked manually, risking human error
  • SSH keys never expire by default, requiring additional metadata for lifecycle management
  • Risk of leaked keys and unauthorized access increases

Solution: SSH Key Management software automates discovery, creation, rotation, revocation, and expiration of SSH keys.

👥 Who Needs SSH Key Management?

Roles:

  • Cybersecurity, IT Security, InfoSec teams
  • CISO, CIO
  • System Administrators, DevOps engineers

Industries (by precedence):

  • Financial Services
  • Public Sector
  • Industrial & Manufacturing
  • Health & Pharmaceuticals
  • Technology & Software
  • Retail & Consumer Products
  • Energy & Utilities
  • Transportation & Hospitality

🔄 SSH Key Lifecycle Stages

  1. Discovered
  2. Generated
  3. Installed
  4. Associated
  5. Rotated
  6. Expired
  7. Revoked

Each stage should have clear security policies and automated processes where possible.
