The NIST Cybersecurity Framework has long defined a clear path for securing systems, data, and access. But most defenders still treat identities as if they are only human. They aren’t. Modern infrastructure runs on a dense web of machine accounts, service principals, API keys, and automated agents. These are non-human identities, and they hold the same—or often greater—privilege than their human counterparts.
Under the Identify function of the NIST Cybersecurity Framework, non-human identities must be inventoried, classified, and understood. Without that baseline, no further step has integrity. Every microservice in your stack, every CI/CD runner, every IoT endpoint is a threat vector if its credentials are unmanaged.
In the Protect function, policies must account for these entities directly. Rotate keys on a strict schedule. Bind permissions to the minimum exposure necessary. Log and encrypt every request, not just human logins.
Detect means more than monitoring user accounts for anomalies. Apply behavioral analytics to machine identities. Sudden surges in API calls, changes in execution patterns, or unexplained deployments can be early signs of compromise.
