Configure Guest Access Expiration for Energy & Utilities
How energy & utilities organizations should implement EXT-04 for Microsoft 365 security and compliance.
For energy & utilities companies using Microsoft 365, configure guest access expiration is a security priority. This guide explains how EXT-04 helps energy & utilities organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Energy & Utilities Organizations Need This Control
Energy & Utilities organizations face specific regulatory requirements including nist-800-53, cis, iso27001. The EXT-04 control helps address these requirements by:
- Guest accounts have expiration dates configured
- Guest access expires after 90 days unless renewed
- Access reviews are configured for guest users
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.
Industry-Specific Considerations
When implementing EXT-04 in a energy & utilities environment, consider:
- **Regulatory requirements**: nist-800-53, cis, iso27001 may mandate specific configurations
- **Risk tolerance**: Energy & Utilities organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections

EXT-04 requires the following configuration:
- Guest accounts have expiration dates configured
