Limit Global Administrators to 2-4 for Energy & Utilities
How energy & utilities organizations should implement PA-01 for Microsoft 365 security and compliance.
Energy & Utilities organizations face unique security challenges when managing Microsoft 365 environments. The PA-01 control (Limit Global Administrators to 2-4) is particularly important for this sector due to nist-800-53 and cis requirements.
Why Energy & Utilities Organizations Need This Control
Energy & Utilities organizations face specific regulatory requirements including nist-800-53, cis, iso27001. The PA-01 control helps address these requirements by:
- Between 2 and 4 principals have the Global Administrator role
- No single point of failure (minimum 2)
- Attack surface is minimized (maximum 4)
- No service principals have Global Administrator (use least-privilege)
- No groups have Global Administrator (hidden privilege escalation risk)
Global Administrators have unrestricted access to your entire tenant. Too many increases your attack surface; too few risks lockout. Service principals and groups with Global Admin are especially dangerous - service principals can be compromised via app credentials, and groups hide who actually has the role. Microsoft recommends 2-4 permanent Global Admins for most organizations.
Industry-Specific Considerations
When implementing PA-01 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
Implementation Steps
To implement PA-01 in your Microsoft 365 environment:
- Between 2 and 4 principals have the Global Administrator role
- No single point of failure (minimum 2)
- Attack surface is minimized (maximum 4)
- No service principals have Global Administrator (use least-privilege)
- No groups have Global Administrator (hidden privilege escalation risk)
This control requires manual implementation through the Entra admin center.
Energy Compliance Requirements
Energy organizations must comply with these frameworks, all of which address limit global administrators to 2-4:
Why This Control Matters for Energy
Global Administrators have unrestricted access to your entire tenant. Too many increases your attack surface; too few risks lockout. Service principals and groups with Global Admin are especially dangerous - service principals can be compromised via app credentials, and groups hide who actually has the role. Microsoft recommends 2-4 permanent Global Admins for most organizations.
Common threats in energy & utilities:
- • Nation-state attacks on infrastructure
- • Ransomware targeting OT systems
- • Insider threats in control rooms
For energy & utilities organizations, PA-01 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
