We implemented just-in-time privileged access by adopting PIM/JIT and replacing standing privileges with time-bound, audited sessions while enforcing phishing-resistant MFA for admin roles. Short-lived elevation requests required conditional access checks such as device compliance before issuing credentials, and all sessions were logged for post-incident review. To keep break-glass workable we retained a minimal, highly audited emergency path that requires multi-party approval and offline verification before elevation. The policy-as-code control that materially reduced standing admin rights was an automation that disabled or revoked unused privileged accounts and converted third-party standing access into time-bound, audited sessions.
We basically used OIDC as our orchestration layer and tied it directly to WebAuthn. The logic is pretty straightforward: a successful hardware handshake serves as the cryptographic proof of presence we need to mint a short-lived session. We got rid of persistent roles entirely. Now, engineers just request access for a specific window, and the system generates a hardware-backed credential that's designed to expire automatically. The big concern with a setup like this is getting locked out if your identity provider goes down. To keep break-glass workable, we decoupled the emergency path from the standard OIDC flow. We use a multi-signature physical key ceremony for those "in case of emergency" moments. It keeps the path open but ensures those accounts stay dormant and heavily monitored unless things have really gone sideways. On the policy-as-code side, the one move that really changed the game for us was an automated enforcement gate. It rejects any IAM provision that doesn't have a "Duration" tag. By treating standing privileges as a build failure, we forced every single administrative action to be ephemeral. That one automation effectively killed the "permanent admin" as a valid state in our system. Honestly, based on what we've seen, removing those static, long-lived credentials is the single most effective way to stop an attacker from moving laterally during a breach. Shifting to zero standing privileges is honestly as much about culture as it is about the tech. You have to balance the developer's need to move fast with the organization's need for a defensible perimeter. But once that automation is live, the security ROI is immediate. It's all about making the secure path the path of least resistance for the engineering team.
