Risk Register Examples for Cyber Security

Standard Operating Procedure: Cyber Security Risk Register Implementation

---

1. Executive Summary & Purpose

This SOP dictates the standardized framework for the identification, documentation, assessment, and remediation tracking of cyber security risks within Template Registry. The purpose is to maintain a centralized, institutional-grade Risk Register that enables leadership to make risk-informed decisions regarding infrastructure hardening and compliance posture.

2. Scope & Prerequisites

• Scope: All digital assets, cloud infrastructure, third-party integrations, and data handling processes.
• Prerequisites:
  • Access to the centralized Risk Management Information System (RMIS) or GRC platform.
  • Latest version of the Asset Inventory & Data Classification document.
  • NIST CSF 2.0 or ISO 27001 control framework documentation.

3. Roles & Responsibilities (RACI)

4. Step-by-Step Procedure

Phase I: Risk Identification

• Conduct bi-weekly threat modeling sessions for critical services.
• Review vulnerability scan results (CVSS v3.1/4.0 scores).
• Document the risk description: [Asset] is threatened by [Threat Actor/Event] resulting in [Business Impact].

Phase II: Assessment & Scoring

• Calculate Inherent Risk = (Likelihood × Impact). Use the 5x5 Matrix (Negligible to Catastrophic).
• Identify existing mitigating controls (e.g., MFA, encryption, WAF).
• Calculate Residual Risk = Inherent Risk − Effectiveness of Controls.

Phase III: Treatment & Monitoring

• Assign treatment strategy: Avoid, Mitigate, Transfer, or Accept.
• Assign a unique Risk ID and primary owner.
• Define a "Risk Appetite" threshold; residual risks exceeding this must trigger an automated escalation to the CISO.

5. Quality Assurance & Pro-Tips

Best Practices

• Dynamic Updating: A risk register is a living document. Static registers are obsolete the moment they are printed.
• Contextualization: Do not record "Unpatched Server" as a risk. Record: "Unauthorized remote code execution on the production database server via vulnerability CVE-202X-XXXX."

Common Pitfalls

• Overloading: Avoid logging "noise" (low-impact vulnerabilities). Focus on risks that jeopardize the Confidentiality, Integrity, and Availability (CIA) triad.
• Lack of Ownership: A risk without a designated owner is a risk that will never be mitigated.

Metric Thresholds

• Acceptance Limit: Only "Low" risks can be accepted without senior executive sign-off.
• Remediation SLA: Critical risks (High/Extreme) must reach a remediation plan status within 72 hours of identification.

6. Frequently Asked Questions (FAQ)

Q: How do we differentiate between a "Vulnerability" and a "Risk"? A: A vulnerability is a technical weakness (e.g., an unpatched port). A risk is the manifestation of that vulnerability resulting in a business loss (e.g., data exfiltration leading to a $50k fine). Register the risk, not the bug.

Q: What if the residual risk remains high after mitigation? A: You must document an "Exception Request." This requires the Asset Owner to formally acknowledge the risk, document compensating controls, and obtain written sign-off from the CISO.
