API Security
API Security is the practice of protecting APIs from unauthorized access and abuse through authentication, authorization, rate limiting, and monitoring. APIs are the new attack surface — they enable programmatic access that bypasses traditional user-centric security controls.
# WHAT TEAMS RUN INTO
- —
APIs are provisioned without matching the same access governance as user access. A service account gets blanket API permissions that would never be granted to a human.
- —
API tokens lack rotation discipline. Long-lived tokens are issued and forgotten. Years later, the token is still valid, nobody remembers why it was issued, and it becomes an orphaned access vector.
- —
API monitoring is sparse. Applications call APIs silently in the background. Abuse and exfiltration can happen for weeks before anyone notices unusual traffic patterns.
# WHY IT MATTERS
APIs are where humans and machines access your systems with equal privilege. But API access is often treated as less risky than user access, granted more broadly, and monitored less carefully. Every API access is an identity decision — an API token saying 'this process has permission to do this action.' When API identity decisions are made carelessly, you are handing out blank checks to invisible processes.
