Privileged access governance in banking: is your evidence complete?

TL;DR: As banks grow through cloud adoption, M&A, service-account sprawl, and automation, privileged access governance becomes harder to explain and evidence, leaving IGA and PAM coverage gaps that regulators care about, according to Hydden. The core problem is not whether access is intended to be governed, but whether governance can still be demonstrated continuously at scale.

Questions worth separating out

Q: How should banks govern privileged access when cloud and M&A expand the identity estate?

A: Banks should move from periodic validation to continuous reconciliation.

Q: Why do service accounts create more privileged access risk than teams often expect?

A: Service accounts create risk because they are easy to over-provision, hard to explain, and often left outside the same review discipline applied to human users.

Q: What breaks when privileged access is managed through scripts and manual reconciliation?

A: Coverage becomes assumed rather than measured.

Practitioner guidance

• Move privileged access into continuous reconciliation Continuously compare discovered privileged identities against what is governed in PAM and IGA, then flag any drift with system, owner, and exception context.
• Classify service accounts as governed identities Assign ownership, purpose, expiry, and review cadence to service accounts and other non-human identities so they are not left to scripts or tribal knowledge.
• Replace informal exception handling with timed approvals Require documented exception workflows with an expiry date, approver, and revalidation trigger so temporary access does not become permanent by default.

What's in the full article

Hydden's full analysis covers the operational detail this post intentionally leaves for the source:

• How its reconciliation model maps discovered privileged access back to existing PAM and secrets platforms
• The control evidence and audit-trail outputs banks would need for supervisory review
• How drift is classified when administrative access appears outside governed scope
• Why continuous discovery changes attestation quality across cloud and legacy estates
