📖 What is Privileged Identity Management (PIM)?
Privileged Identity Management (PIM) is a service in Microsoft Entra ID that provides just-in-time (JIT) administrative access. It allows users to request elevated permissions for a limited duration, requiring approval or justification to reduce the risk of permanent standing privileges.
"PIM is critical for reducing the attack surface; focus on the 'eligible' vs. 'active' assignment status for administrators."

🔑 What are the Key Concepts of Privileged Identity Management (PIM)?
- ▸ Eligible assignments allow users to activate a role only when needed, preventing permanent standing access and reducing the risk of credential theft.
- ▸ Active assignments grant immediate, permanent permissions, typically reserved for emergency 'break-glass' accounts that must bypass PIM activation processes.
- ▸ Just-In-Time (JIT) access ensures permissions are time-bound, automatically expiring after a set duration to minimize the window of potential exploitation.
- ▸ Approval workflows require a designated approver to authorize role activation, adding a layer of governance for highly sensitive administrative roles.
- ▸ Access Reviews periodically force administrators to justify why users still need eligibility, ensuring the principle of least privilege is maintained.
🎯 How does Privileged Identity Management (PIM) appear on the MS-102 Exam?
You may be asked to design a strategy to reduce the attack surface of a tenant by converting permanent Global Administrator assignments into eligible roles with required MFA.
A scenario might describe a requirement where a user must provide a business justification and obtain manager approval before accessing the Exchange Administrator role for a limited window.
Expect questions where you must identify why a user cannot manage a service despite being assigned a role; the answer often involves the user failing to activate their eligible assignment.
❓ Frequently Asked Questions
What is the primary difference between an eligible and an active assignment in PIM?
Eligible users must perform an activation step, such as MFA or providing a justification, to gain the role. Active users possess the permissions permanently without any activation process.
Can PIM be used to manage group memberships instead of just individual roles?
Yes, PIM for Groups allows you to make users eligible for group membership, granting them all the permissions associated with that group only upon successful activation.
How does PIM integrate with the principle of least privilege?
PIM enforces least privilege by ensuring users only have high-level permissions during the specific window they are performing a task, rather than having them enabled 24/7.
