PIM operational playbook

Deploying Privileged Identity Management (PIM) is the easy part — configure roles, enable users as eligible, you're done. The interesting question is how PIM works as a daily operation: how admins activate roles, who approves, how audit happens, when reviews fire. A working operational playbook makes PIM a healthy practice rather than a one-time deployment.

The basic activation flow

For an eligible admin:

1. They need to perform a privileged operation (assign a licence, modify a Conditional Access policy, restore a deleted user).
2. They go to Entra admin center → Privileged Identity Management → My roles (or via entra.microsoft.com/PrivilegedAccess).
3. They click Activate on the relevant eligible role.
4. PIM may prompt for:
   • MFA confirmation (even though they signed in earlier).
   • Justification text — why they need the role.
   • Ticket reference — link to the change ticket or incident.
   • Approval — for high-privilege roles, an approver must confirm.
5. Once activated, the role is active for a configured duration (typically 1–8 hours).
6. After duration, the role automatically deactivates.

Configuration recommendations

For each Entra ID role, configure:

• Maximum activation duration — match to the work duration. 4 hours is a reasonable default; less for very sensitive roles.
• MFA at activation — yes, always.
• Justification required — yes. Force admins to articulate why.
• Ticket information — yes, where you have a ticket system. Helps audit.
• Approval required — for Global Administrator, Privileged Role Administrator, and similar high-power roles. Multiple approvers prevent single-approver bottlenecks.

Approval design

For approval-required roles, who approves matters:

• Peer approval — another eligible admin in the same role. Fastest; some risk of mutual approval ("I approve yours, you approve mine").
• Manager approval — the admin's manager. Slower but adds organisational oversight.
• Security team approval — dedicated approval pool. Slowest, strongest oversight.

A pragmatic approach: peer approval for common cases (User Administrator, etc.), security team approval for the strongest roles (Global Administrator).

Break-glass accounts

PIM doesn't eliminate the need for break-glass accounts — emergency-access accounts excluded from CA policies, with very strong unique credentials stored offline. PIM eligibility chains can have circular failures (the only PIM approver is unreachable, so nobody can activate). Break-glass solves that.

Document break-glass procedures. Monitor for unauthorised use. Rotate credentials periodically.

Access reviews

The other half of PIM is access reviews — periodic recertification of who's eligible for what.

Configure for each privileged role:

• Recurrence — quarterly is common; semi-annual for less sensitive roles.
• Reviewer — the admin themselves (self-attestation), their manager, or a named security reviewer.
• Action on no response — typically "remove eligibility" so absent attestation defaults to removal.

Access reviews prevent the slow drift where someone gets a role for one project and keeps it indefinitely.

Audit and reporting

PIM activity logs in the Entra audit log:

• Every activation request (approved or denied).
• Every approval action.
• Every access review outcome.
• Every role assignment change.

Pull these into your SIEM / Microsoft Sentinel for cross-correlation with other signals.

Operational metrics

A healthy PIM practice produces measurable signals:

• Time-to-activate — should be under 5 minutes for self-activation, under 30 minutes for approver-needed.
• Approval rate — most should be approved (otherwise eligibility is wrong); high denial rate means scope problem.
• Active hours per admin per month — actual usage; suggests right-sizing.
• Standing assignments — should be near zero except for break-glass.

For Microsoft 365 tenants with serious security posture, PIM with this operational discipline is one of the highest-leverage controls available. Standing admin access is one phish away from disaster; PIM makes it not.
