Policy, Procedure, and Plan Documentation in Security & Privacy Controls Implementation
Understanding Policy, Procedure, and Plan Documentation
Policy, Procedure, and Plan Documentation is a foundational element in the implementation of security and privacy controls within the Governance, Risk, and Compliance (GRC) framework. This topic is critical for CGRC (Certified in Governance, Risk, and Compliance) exam candidates because it underpins how organizations formally establish, communicate, and enforce their security and privacy posture.
Why Is Policy, Procedure, and Plan Documentation Important?
Documentation serves as the backbone of an organization's security and privacy program. Without proper documentation, controls cannot be consistently implemented, monitored, or assessed. Here are the key reasons why this topic matters:
1. Accountability and Authority: Policies establish management's intent and direction. They define what must be done and assign responsibility. Without policies, there is no authoritative basis for requiring compliance.
2. Consistency: Procedures ensure that security and privacy tasks are performed uniformly across the organization. This reduces variability and human error.
3. Audit and Assessment Readiness: Assessors, auditors, and regulators expect to see documented policies, procedures, and plans. These documents serve as evidence that controls are designed, implemented, and operating as intended.
4. Risk Management Foundation: Plans document how security and privacy controls will be implemented and managed over time, supporting the organization's risk management strategy.
5. Legal and Regulatory Compliance: Many laws, regulations, and standards (e.g., FISMA, HIPAA, NIST SP 800-53, GDPR) explicitly require documented policies, procedures, and plans.
6. Communication: Documentation communicates expectations to all stakeholders, from executives to end users, ensuring everyone understands their roles and responsibilities.
What Are Policies, Procedures, and Plans?
It is essential to understand the distinctions between these three types of documents, as exam questions frequently test your ability to differentiate them.
Policies:
- High-level statements of management intent, expectations, and direction.
- Define what the organization requires (not how to do it).
- Approved by senior management or an authorizing official.
- Typically organization-wide or applicable to specific domains (e.g., access control policy, incident response policy).
- Should include: purpose, scope, roles and responsibilities, compliance requirements, and consequences for non-compliance.
- Example: "All users must use multi-factor authentication when accessing organizational information systems."
Procedures:
- Step-by-step instructions that describe how to implement or carry out a policy.
- Operational in nature and designed for the personnel performing the tasks.
- More detailed and technical than policies.
- May change more frequently as technology and processes evolve.
- Example: "Step 1: Navigate to the MFA enrollment portal. Step 2: Select your authentication method. Step 3: Register your device..."
Plans:
- Documents that describe the overall approach to implementing and managing security and privacy controls.
- Include timelines, milestones, resource allocation, and responsibilities.
- Key plans include: System Security Plan (SSP), Security Assessment Plan (SAP), Plan of Action and Milestones (POA&M), and Continuous Monitoring Plan.
- The System Security Plan (SSP) is particularly important as it describes the security controls selected for a system and how they are implemented.
- Example: "The organization will implement encryption on all endpoints by Q3 2025, with the IT Security team leading the deployment and the CISO approving the final configuration."
How Does Policy, Procedure, and Plan Documentation Work in Practice?
The documentation lifecycle within the NIST Risk Management Framework (RMF) and GRC context follows a structured approach:
1. Development:
- Policies are developed based on organizational mission, legal requirements, risk assessments, and industry best practices.
- Procedures are developed to operationalize policies.
- Plans are created during the system authorization process and updated throughout the system lifecycle.
2. Review and Approval:
- Policies require senior management or authorizing official approval.
- Procedures are typically approved by system owners or functional managers.
- Plans are reviewed and approved as part of the authorization process (e.g., the Authorizing Official reviews and approves the SSP).
3. Dissemination:
- Documentation must be distributed to all relevant personnel.
- Access should be controlled to ensure sensitive details are protected while ensuring availability to those who need it.
4. Implementation:
- Personnel follow procedures to implement the controls described in policies and plans.
- The SSP serves as the primary reference for how controls are implemented in a specific system.
5. Assessment:
- During security assessments, assessors evaluate whether documented policies, procedures, and plans are adequate and whether actual practices align with the documentation.
- The Security Assessment Plan (SAP) defines how the assessment will be conducted.
- The Security Assessment Report (SAR) documents findings.
6. Maintenance and Update:
- Documentation must be reviewed and updated regularly (typically annually or when significant changes occur).
- Changes in technology, threats, regulations, or organizational structure may necessitate updates.
- Version control and change management processes should be applied to all documentation.
Key NIST SP 800-53 Control Families Related to Documentation:
Nearly every control family in NIST SP 800-53 includes requirements for policies and procedures. For example:
- PL (Planning): Covers the System Security Plan, rules of behavior, and security planning policy.
- PM (Program Management): Addresses the information security program plan and related organizational policies.
- CA (Assessment, Authorization, and Monitoring): Includes security assessment plans and POA&Ms.
- Each control family (AC, AU, AT, CM, CP, IA, IR, MA, MP, PE, PS, RA, SA, SC, SI, SR, PT, etc.) typically begins with a control requiring a policy and associated procedures for that domain.
The Hierarchy of Documentation:
Understanding the hierarchy is critical for exam success:
1. Laws and Regulations (external mandates, e.g., FISMA, HIPAA)
2. Standards and Guidelines (e.g., NIST SP 800-53, FIPS 199, FIPS 200)
3. Organizational Policies (derived from laws, regulations, and standards)
4. Procedures (derived from policies)
5. Plans (describe how controls will be implemented and managed)
6. Baselines and Configurations (technical implementation details)
Common Documentation Artifacts in the RMF Process:
- System Security Plan (SSP): Describes the system, its boundary, the controls selected, and how they are implemented. This is the most critical document for system authorization.
- Security Assessment Plan (SAP): Outlines the scope, methodology, and procedures for assessing controls.
- Security Assessment Report (SAR): Documents the results of the assessment, including findings and recommendations.
- Plan of Action and Milestones (POA&M): Tracks identified weaknesses, planned remediation actions, responsible parties, and timelines.
- Authorization Package: Includes the SSP, SAR, and POA&M, submitted to the Authorizing Official for a risk-based authorization decision.
- Continuous Monitoring Strategy/Plan: Describes how the organization will maintain ongoing awareness of security posture.
How to Answer Exam Questions on Policy, Procedure, and Plan Documentation
Exam questions on this topic typically test your ability to:
1. Differentiate between policies, procedures, and plans.
- If the question asks about what must be done → the answer is likely a policy.
- If the question asks about how to do something step-by-step → the answer is likely a procedure.
- If the question asks about the approach, timeline, or strategy for implementing controls → the answer is likely a plan.
2. Identify the correct document for a given scenario.
- A scenario describing the overall security posture of a system → System Security Plan (SSP).
- A scenario describing how an assessment will be conducted → Security Assessment Plan (SAP).
- A scenario tracking remediation of weaknesses → Plan of Action and Milestones (POA&M).
3. Understand approval authorities.
- Policies → approved by senior management or Authorizing Official.
- Procedures → approved by system owners or functional managers.
- SSP → reviewed by assessors, approved by the Authorizing Official as part of the authorization decision.
4. Know the review and update cycle.
- Documentation should be reviewed at least annually or when significant changes occur.
- The POA&M is a living document updated continuously as weaknesses are addressed.
Exam Tips: Answering Questions on Policy, Procedure, and Plan Documentation
Tip 1: Focus on the "What" vs. "How" Distinction
The most common trap in exam questions is confusing policies with procedures. Remember: policies state what is required; procedures describe how to accomplish it. If you see words like "step-by-step," "instructions," or "detailed process," the answer is a procedure. If you see words like "management direction," "requirements," or "expectations," the answer is a policy.
Tip 2: Know the Key Documents in the Authorization Package
The authorization package consists of three core documents: SSP, SAR, and POA&M. Questions may ask what documents the Authorizing Official reviews to make a risk-based authorization decision. Always remember this triad.
Tip 3: Understand That Every Control Family Requires Policies and Procedures
NIST SP 800-53 requires that each control family has an associated policy and procedures. This is a common knowledge-check question. The first control in most families (e.g., AC-1, AU-1, IR-1) addresses the requirement for policy and procedures for that family.
Tip 4: Remember the Role of the System Security Plan (SSP)
The SSP is the cornerstone of the authorization process. It describes the system boundary, environment, controls, and implementation details. If a question asks about the primary document that describes how security controls are implemented for a system, the answer is the SSP.
Tip 5: Don't Confuse Plans with Policies
A plan is forward-looking and describes how the organization will achieve a goal over time (with timelines, milestones, and resources). A policy is a standing directive. If the question describes a time-bound implementation strategy, the answer is a plan.
Tip 6: Pay Attention to Who Approves What
Exam questions often test governance knowledge. The Authorizing Official (AO) makes the authorization decision based on the authorization package. The system owner is responsible for the SSP. The information owner/steward defines data handling requirements. The CISO/SAISO typically oversees the organizational security program and related policies.
Tip 7: Look for Keywords in the Question Stem
- "Management intent" or "organizational direction" → Policy
- "Step-by-step" or "detailed instructions" → Procedure
- "Implementation approach" or "milestones" → Plan
- "Findings" or "assessment results" → Security Assessment Report (SAR)
- "Remediation tracking" or "corrective actions" → POA&M
- "System description and control implementation" → SSP
Tip 8: Understand the Continuous Monitoring Connection
Documentation is not a one-time activity. Continuous monitoring requires that policies, procedures, and plans be regularly reviewed and updated. The continuous monitoring strategy defines how often documentation will be reviewed and what triggers an update. Expect questions that connect documentation maintenance to the continuous monitoring phase of the RMF.
Tip 9: Remember That Documentation Serves as Evidence
During an assessment, documented policies, procedures, and plans serve as evidence that controls exist and are properly designed. Assessors compare documentation to actual practices. A gap between documentation and practice is a finding. Questions may present scenarios where documentation exists but is not followed, or where practices exist but are not documented—both are problems.
Tip 10: Apply the "Organization-Wide vs. System-Specific" Lens
Some policies and plans are organization-wide (e.g., the information security program plan under PM-1), while others are system-specific (e.g., the SSP for a particular system). Questions may test whether you can distinguish between organizational-level and system-level documentation.
Tip 11: Use the Process of Elimination
When faced with a difficult question, eliminate answers that clearly don't fit the definition. If the answer choice describes a high-level management statement, it's a policy. If it describes technical steps, it's a procedure. If it describes a roadmap for achieving security objectives, it's a plan. If it describes test results, it's a report.
Summary
Policy, Procedure, and Plan Documentation is a critical competency area for the CGRC exam. Success requires understanding the clear distinctions between these document types, knowing which documents are required at each phase of the RMF, understanding who is responsible for creating and approving each document, and recognizing that documentation must be maintained as a living set of artifacts throughout the system lifecycle. By mastering these concepts and applying the exam tips above, you will be well-prepared to answer questions on this topic with confidence.
