Human, machine and AI identities: what IAM teams need to know

TL;DR: Identity-related breaches are now a board-level identity security problem, according to CyberArk, citing 87% of organisations that have experienced at least two successful breaches and framing privileged controls, lifecycle governance and continuous discovery as the core response. The real issue is not adding more access tooling, but treating every identity type as part of one governance model.

NHIMG editorial — based on content published by CyberArk: securing every identity with the right level of privilege controls

By the numbers:

• 87% of organizations have experienced at least two successful identity-related breaches.
• Only 5.7% of organizations have full visibility into their service accounts.
• 97% of NHIs carry excessive privileges, increasing unauthorized access and broadening the attack surface.

Questions worth separating out

Q: How should security teams govern machine and AI identities alongside human users?

A: Treat them as one identity programme with different lifecycle rules, not as separate security domains.

Q: Why do excessive privileges create such a large identity security risk?

A: Because any identity with more access than it needs has a larger blast radius when credentials are stolen or sessions are abused.

Q: What do organisations get wrong about identity lifecycle management?

A: They often manage joiner, mover and leaver processes well for employees but leave non-human identities outside the same discipline.

Practitioner guidance

• Unify identity inventory across all actor types Map workforce accounts, service accounts, tokens, certificates and AI identities into one authoritative register, then assign an owner and business purpose to each identity.
• Separate standing privilege from task-based access Review privileged entitlements for persistent access that can be replaced with just-in-time elevation, session scoping or narrower role boundaries.
• Make lifecycle ownership explicit for non-human identities Require creation, rotation, recertification and offboarding steps for service accounts, API keys and certificates, with a named human owner for each.
