Common Entra ID Security Assessment Findings - Part 3: Weak Privileged Identity Management Configuration

The examples provided illustrate the importance of robust security configurations, particularly when dealing with Privileged Identity Management (PIM) and Multi-Factor Authentication (MFA). Here are key takeaways from each example:

Example 1: PIM Role Activation Without MFA Enforcement

Scenario Overview:

• Alice obtains administrative privileges through a session that does not enforce MFA.
• An attacker steals tokens from this session, gaining access to powerful tokens without completing MFA.

Key Points:

1. MFA Requirement During Token Issuance:

   • If the initial token issuance (e.g., for an admin portal) requires MFA, even if PIM does not enforce MFA during role activation, the attacker cannot obtain a powerful token initially.

2. PIM Role Activation Security:

   • Enforcing re-authentication with MFA during PIM role activation significantly increases security by ensuring that only users who complete MFA can activate roles.

3. Token Lifetimes and Renewals:

   • Limiting the lifetime of tokens through Conditional Access policies can prevent attackers from using stolen refresh tokens indefinitely.

4. Pre-Consented Permissions:

   • Pre-consented permissions in tokens issued for
