Control 2.10: Patch Management and System Updates

Control ID: 2.10 Pillar: Management Regulatory Reference: GLBA 501(b), SOX 404, FINRA 4511, SEC 17a-4 Last UI Verified: January 2026 Governance Levels: Baseline / Recommended / Regulated Last Verified: 2026-02-03

Objective

Implement structured patch management for AI agent infrastructure including Power Platform, Copilot Studio, and dependent Azure services to maintain security posture, operational stability, and regulatory compliance.

Why This Matters for FSI

  • GLBA 501(b): Patch management protects customer information through vulnerability remediation
  • SOX 404: Documented update processes provide internal control evidence
  • FINRA 4511: Patch records demonstrate system maintenance for books and records
  • SEC 17a-4: System update documentation supports recordkeeping requirements

Control Description

This control establishes patch management through:

  1. Update Monitoring - Track Microsoft 365 Message Center and Azure Service Health
  2. Impact Assessment - Evaluate updates for agent compatibility and business impact
  3. Testing Protocol - Test updates in non-production before production deployment
  4. Deployment Windows - Define maintenance windows aligned with business operations
  5. Rollback Procedures - Document rollback plans for failed updates
  6. Documentation - Maintain patch history for compliance evidence

Key Configuration Points

  • Subscribe to Microsoft 365 Message Center for Power Platform and Copilot Studio updates
  • Configure Azure Service Health alerts for relevant services
  • Establish testing environment mirroring production configuration
  • Define maintenance windows (recommended: weekends for Zone 3 agents)
  • Create pre/post-patch verification checklists
  • Document patch decisions and deployment outcomes in change management system
  • Configure auto-update settings based on governance zone

Zone-Specific Requirements

Zone Requirement Rationale
Zone 1 (Personal) Auto-updates enabled; monthly review of changes Low risk, minimal coordination needed
Zone 2 (Team) Test critical updates; 48-hour validation window; documented deployment Shared agents warrant controlled updates
Zone 3 (Enterprise) Full change control; mandatory testing; defined maintenance windows; rollback plans Customer-facing requires maximum stability

Roles & Responsibilities

Role Responsibility
Power Platform Admin Monitor updates, coordinate deployments, execute patches
Change Manager Approve patch schedules, manage change tickets
QA Lead Execute testing protocol, validate post-patch functionality
Agent Owner Assess business impact, approve maintenance windows
Control Relationship
2.3 - Change Management Patches follow change management process
2.4 - BC/DR Rollback procedures align with recovery plans
2.9 - Performance Monitoring Monitor performance pre/post patch
1.7 - Audit Logging Patch events captured in audit logs

Implementation Playbooks

Step-by-Step Implementation

This control has detailed playbooks for implementation, automation, testing, and troubleshooting:

Verification Criteria

Confirm control effectiveness by verifying:

  1. Message Center subscription configured for Power Platform updates
  2. Azure Service Health alerts trigger notifications to operations team
  3. Test environment mirrors production configuration
  4. Recent patch deployment follows documented change process
  5. Patch history log maintained with deployment outcomes
