Configure Guest Access Expiration for ISO 27001 Compliance

Learn how EXT-04 helps you meet ISO 27001 requirements for Microsoft 365 and Entra ID security.

Meeting ISO 27001 standards for Microsoft 365 involves implementing controls like EXT-04 (Configure Guest Access Expiration). This guide covers the specific ISO 27001 requirements addressed by this control and how to achieve compliance.

How EXT-04 Addresses ISO 27001 Requirements

ISO 27001 requires organizations to implement controls around configure guest access expiration. The EXT-04 control provides:

  • Guest accounts have expiration dates configured
  • Guest access expires after 90 days unless renewed
  • Access reviews are configured for guest users

These measures directly support ISO 27001 compliance by ensuring proper external security in your Microsoft 365 environment.

Implementation for Compliance

To satisfy ISO 27001 requirements with this control:

  • **Enable the control** - Follow the manual configuration steps
  • **Document your implementation** - Record how the control was configured
  • **Maintain evidence** - TrueConfig automatically logs compliance status
  • **Monitor continuously** - Track any deviations from the expected state

Evidence Collection

For ISO 27001 audits, you'll need to demonstrate:

  • Current configuration state
  • Historical compliance data
  • Remediation actions taken
  • Continuous monitoring in place

TrueConfig provides all of this evidence through its audit trail and reporting features.

Why This Control Matters for ISO 27001

Guest accounts created for temporary projects often outlive their intended use. Without expiration, ex-partners and former vendors retain access indefinitely. Automatic expiration ensures guest access is time-bound.

Implementing EXT-04 is an important step toward ISO 27001 compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to ISO 27001 requirements.
