To make an outage-tracking workflow with an Outage Management System (OMS) NERC CIP compliant, the key is to treat the OMS as part of your Bulk Electric System (BES) Cyber System environment and then ensure the workflow is controlled by your entity’s documented CIP program, asset classification, access control, logging, change management, and recovery processes.

Here’s a practical way to approach it:

1) First determine whether the OMS is in scope

Not every OMS is automatically subject to every CIP requirement.

• Identify whether the OMS supports a BES Cyber System or is used to operate/control/monitor BES assets.
• Determine whether it is:
  • High/Medium/Low Impact BES Cyber System
  • Electronic Access Control or Monitoring System (EACMS)
  • Physical Access Control System (PACS)
  • Protected Cyber Asset (PCA) or a support system outside scope
• Document the rationale in your CIP asset inventory and classification records.

2) Control access tightly

Your outage workflow likely involves operators, planners, field personnel, contractors, and possibly vendors.

Make sure you have:

• Unique user IDs for all users
• Role-based access control with least privilege
• Multi-factor authentication where required by your classification and access method
• Periodic access reviews
• Immediate revocation when users change roles or leave
• Vendor access controls and approval processes
• No shared accounts except where explicitly justified and controlled by policy

Relevant CIP areas often include:

• CIP-004 Personnel & Training
• CIP-005 Electronic Security Perimeter / Electronic Access Controls
• CIP-007 System Security Management

3) Protect data integrity of outage records

Outage records can affect BES operations, switching, planning, and restoration.

You should ensure:

• Changes to outage records are tracked and attributable
• Critical fields are protected from unauthorized modification
• There is audit logging for create/update/delete actions
• Time stamps are synchronized and trustworthy
• Data retention aligns with your compliance and operational needs
• Any interfaces with SCADA, EMS, mobile apps, or ticketing systems are secured and validated

4) Segment the OMS from less-trusted networks

If the OMS is connected to corporate IT, mobile devices, vendor portals, or cloud services:

• Use network segmentation
• Place externally accessible components behind controlled gateways
• Restrict inbound/outbound traffic to only what is necessary
• Manage remote access with approved methods and monitoring
• Ensure communication paths are documented and protected

This is usually central to CIP-005.

5) Implement secure change management

Outage workflows often evolve, especially if integrated with dispatch, SCADA, GIS, or work management systems.

You need:

• Formal change approval
• Testing before production deployment
• Backout/rollback plans
• Review of security impact for configuration or code changes
• Version control for scripts, integrations, and workflow rules

This aligns strongly with CIP-010 (Configuration Change Management and Vulnerability Assessments).

6) Log and monitor security-relevant events

Your OMS should generate and retain logs for:

• Authentication events
• Privilege changes
• Outage record modifications
• Workflow approvals
• Integration/API activity
• Admin actions
• Failures and exceptions

Also ensure:

• Logs are protected from tampering
• Time synchronization is in place
• Alerts exist for suspicious activity
• Log review procedures are documented

This relates to CIP-007 and often CIP-008 (incident response) depending on use.

7) Secure mobile and remote outage access

If field crews or managers access the OMS from tablets, phones, or remote laptops:

• Require approved managed devices where possible
• Enforce encryption and lockout
• Use secure remote access with MFA
• Prevent local data leakage if outage information is sensitive
• Apply MDM/endpoint controls consistent with policy

This is a frequent compliance gap.

8) Include the OMS in vulnerability and patch management

For in-scope systems:

• Maintain an inventory of software/hardware versions
• Test patches before deployment
• Track remediation timelines
• Compensate for unpatchable vulnerabilities with documented controls
• Conduct vulnerability assessments as required

This maps primarily to CIP-007 and CIP-010.

9) Establish incident response for OMS-related events

Define what happens if:

• Outage data is altered maliciously
• Access is lost
• The OMS is unavailable during a restoration event
• A vendor account is compromised
• A data integration is sending incorrect outage info

Your incident response plan should include:

• Escalation paths
• Containment steps
• Manual fallback procedures
• Restoration priorities
• Evidence preservation

This aligns with CIP-008.

10) Train people on the workflow and compliance expectations

Make sure users understand:

• What outage actions they are authorized to take
• How to distinguish approved vs. emergency changes
• How to report anomalies
• How to handle sensitive operational data
• What to do if the OMS is unavailable

Training evidence matters for auditability.

A simple compliance checklist

Use this as a starting point:

• OMS scope/classification documented
• Users have unique IDs and least-privilege access
• MFA enabled where required
• Remote and vendor access controlled and logged
• Network segmentation and perimeter controls in place
• Audit logging enabled for outage record changes
• Change management and testing procedures documented
• Vulnerability/patch management process in place
• Incident response and manual fallback procedures documented
• Access reviews and training completed on schedule
• Data retention and integrity controls implemented
• Interfaces/APIs secured and monitored

Important caveat

“NERC CIP compliant” is not something you can certify by workflow alone. It depends on:

• Whether the OMS is in CIP scope
• How it is connected to BES Cyber Systems
• Your entity’s approved interpretations, risk assessments, and documentation
• The exact CIP version and applicability

So the best practice is to run the workflow through:

1. Asset classification
2. Control mapping
3. Gap assessment
4. Documented remediation
5. Internal audit / compliance review
