How to Build a GRC Controls Library From Scratch

You've joined a company where the Governance, Risk, and Compliance (GRC) program is... immature at best. There are policies and standards that vaguely point to NIST CSF controls—and that's where the trail ends. You're left trawling through loads of different standards docs, trying to connect the dots and figure out what problems you're even supposed to be solving.

Sound familiar?

As a GRC professional in this environment, you might also feel the weight of that perception: the "useless pencil pushers department" stigma that suggests your work isn't technical enough or doesn't bring sufficient value to the table.

This guide is for you. We'll provide a practical, no-nonsense approach to building a GRC controls library from scratch using nothing more complex than a spreadsheet. No expensive tools with high learning curves required—just a straightforward method to organize chaos, demonstrate immediate value, and build a common language for risk and compliance across your organization.

Why a Controls Library is Your GRC Foundation

Before diving into the how-to, let's understand why this matters.

Governance, Risk, and Compliance (GRC) isn't just a department—it's "an integrated collection of capabilities that enable organizations to reliably achieve objectives, address uncertainty, and act with integrity." This concept, known as Principled Performance, was defined by the Open Compliance and Ethics Group (OCEG), which created the GRC Capability Model (Red Book) as the authoritative guide for professionals.

Without an integrated approach, departments become siloed, costs increase, risk visibility diminishes, and inefficiencies multiply. The financial impact is staggering—over $1 trillion is lost annually by organizations due to "unprincipled misconduct and errors."

A controls library is your first line of defense against this chaos. It provides:

Without a controls library, you're essentially "blindly throwing darts at a board"—implementing security measures without a structured understanding of your requirements or gaps.

Step-by-Step: Building Your GRC Controls Library in a Spreadsheet

You don't need Archer, ServiceNow, or other complex GRC platforms to get started. A well-structured spreadsheet is a powerful first step that provides immediate value while setting the foundation for more sophisticated approaches later.

Step 1: Define Scope, Purpose, and Applicable Frameworks

Before creating a single control, ask: "What are the organizational goals we need to support?"

Identify the key drivers for your GRC program:

• Regulatory compliance requirements
• Contractual obligations
• Customer expectations
• Industry standards
• Risk management objectives

Then, determine which frameworks apply to your organization. Common ones include:

• NIST CSF (Cybersecurity Framework)
• NIST 800-53 (Security and Privacy Controls)
• ISO 27001 (Information Security Management)
• PCI DSS (Payment Card Industry Data Security Standard)
• SOC 2 (Service Organization Control)

Pro Tip: Focus on the most critical frameworks first. Don't try to boil the ocean—you can expand your library over time.

Step 2: Establish Your Core Data Points (The Spreadsheet Columns)

Create a simple spreadsheet with these essential columns:

• Control ID: A unique identifier for every control (e.g., AC-01, PS-01). This must be consistent and intuitive.
• Control Description: A clear, concise explanation of what the control does and why it matters. Avoid jargon where possible.
• Framework Mapping: This critical column maps each internal control to specific requirements in external frameworks (e.g., maps to NIST CSF PR.AC-1, ISO 27001 A.9.2.1, PCI DSS 8.1.1).
• Control Family: Categorizes controls by domain (e.g., Access Control, Incident Response, Business Continuity).
• Control Owner: The person or team responsible for implementing and maintaining the control.
• Implementation Status: Tracks progress (e.g., Implemented, Not Implemented, In Progress).
• Test of Operating Effectiveness (TOE) Date: When the control was last verified.

This structure forms the backbone of your library and provides the necessary organization to make it useful immediately.

Step 3: Populate Your Library (The Smart Way)

Don't reinvent the wheel! Here's the smart approach to populating your library:

1. Download existing framework controls: As recommended by GRC professionals, "You can download the controls in a spreadsheet from NIST for CSF and 800-53." This provides an immediate head start with authoritative control language.
2. Assess your current state: Review existing policies, procedures, and standards to identify controls already implicitly or explicitly in place.
3. Tailor the language: Rewrite framework control descriptions to fit your organization's context and terminology.
4. Map across frameworks: For each control, identify which requirements it satisfies across multiple frameworks. This is where you create tremendous value—by showing how one control can satisfy requirements from NIST CSF, ISO 27001, PCI, and SOC 2 simultaneously.
5. Identify low hanging fruit: Mark controls that are already implemented or would be easy to implement. This helps demonstrate quick wins.

Example entry:

Control ID: AC-01
Description: The organization establishes and documents access control policies and procedures.
Framework Mapping: NIST CSF PR.AC-1, ISO 27001 A.9.2.1, PCI DSS 8.1.1, SOC 2 CC6.1
Control Family: Access Control
Control Owner: IT Security Team
Implementation Status: Partially Implemented
TOE Date: N/A

Step 4: Review, Validate, and Involve Stakeholders

This is a crucial step that many GRC professionals skip, but it's essential for success. Do not build your library in a silo!

1. Engage department heads: Meet with IT managers, system owners, and department leaders to review the controls for accuracy, feasibility, and completeness.
2. Gather stakeholder input: Use surveys or interviews to collect insights on potential risks and concerns directly from employees who work with these systems daily.
3. Validate control implementation: Verify that controls marked as "implemented" are actually in place and functioning as expected.
4. Adjust based on feedback: Refine control descriptions, ownership assignments, and implementation statuses based on stakeholder input.

Incomplete risk identification often stems from limited stakeholder involvement. By engaging diverse perspectives early, you'll build a more accurate and comprehensive library while generating buy-in from across the organization.

Step 5: Document and Maintain Clear Naming Conventions

Establish and document clear, intuitive naming conventions for your Control IDs. This ensures clarity and makes the library easier to navigate as it grows.

For example:

• AC-XX for Access Control
• IR-XX for Incident Response
• BC-XX for Business Continuity

Maintain comprehensive records of your decisions, implementation approaches, and communications. This facilitates knowledge transfer when personnel changes occur and provides an audit trail for compliance purposes.

Putting Your Controls Library to Work: Initial Risk Assessment

Now comes the exciting part—using your new library to conduct an initial risk assessment that delivers immediate value. This transforms your work from perceived "pencil pushing" to strategic risk management.

A GRC risk assessment is a structured approach to identify and assess threats. Your new controls library serves as the inventory of mitigations for those threats.

Here's the process:

1. Identify Risks: Brainstorm and list potential risks to the organization (e.g., unauthorized access to sensitive data, ransomware attack, data loss).
2. Map Controls: In a new tab of your spreadsheet or a separate risk register, list each risk. Then, map the relevant Control IDs from your library that mitigate each specific risk.
3. Identify Gaps: If you find risks that have no corresponding controls from your library, you've identified a gap. This is a tangible, data-driven insight.
4. Prioritize: Categorize risks by severity and impact to prioritize resource allocation for developing new controls or improving existing ones.

Example of the mapping:

Risk: Unauthorized access to customer data
Potential Impact: High (regulatory fines, reputation damage)
Controls: AC-01, AC-03, AC-17, IA-02
Gaps: No multi-factor authentication requirement (recommended new control)

This process provides immediate, actionable intelligence.

You can now approach leadership with specific insights: "We've identified these critical risks, and here are the controls we have (or don't have) to address them." This elevates the conversation beyond compliance and directly addresses business risk—something the C-suite will understand and value.

Common Pitfalls and Pro Tips for Success

Common Pitfalls:

• Analysis Paralysis: Don't try to be perfect from day one. Start with a basic framework and refine it over time.
• Skipping Stakeholder Input: This leads to an incomplete or impractical library that no one uses.
• Neglecting Updates: Regulations and business needs evolve. Schedule quarterly reviews to keep your library current.

Pro Tips for Success:

• Automate Where Possible: While starting with a spreadsheet is great, as you mature, consider tools like ServiceNow GRC, Archer, or eramba GRC to automate monitoring and reporting.
• Foster Collaboration: Continuously work with IT and management to secure resources and support. GRC is a team sport.
• Embrace Continuous Learning: Stay current on frameworks and threats. As one GRC professional noted, willingness to "read, read, and read some more with the promise to comprehend some or all of it as time goes on" is essential for success in this field.

Frequently Asked Questions (FAQ)

What is a GRC controls library?

A GRC controls library is a centralized inventory of an organization's internal controls, mapping them to requirements from various standards and regulations like NIST CSF or ISO 27001. It acts as a single source of truth for all security and compliance requirements, providing a structured way to understand what measures are in place to mitigate risks. This library forms the foundation for conducting effective risk assessments and ensures a consistent approach to compliance across the organization.

Why should I build a controls library in a spreadsheet?

Building a controls library in a spreadsheet is the most practical and cost-effective first step for an organization with an immature GRC program. It provides immediate value and structure without the high cost and steep learning curve of specialized GRC software. A well-organized spreadsheet allows you to quickly establish a single source of truth, map controls to frameworks, and conduct initial risk assessments. This approach helps you demonstrate quick wins and build a solid foundation that can later be migrated to a more sophisticated GRC platform as your program matures.

How do I select the right compliance frameworks for my controls library?

To select the right frameworks, start by identifying your organization's key GRC drivers, such as regulatory requirements (like PCI DSS), contractual obligations with clients (like SOC 2), and industry standards (like NIST CSF or ISO 27001). Focus on the most critical frameworks first rather than trying to include everything at once. Prioritizing allows you to build a relevant and manageable library that addresses your most pressing compliance and risk management needs.

What is the difference between a control and a risk?

A risk is a potential event or threat that could harm your organization (e.g., a ransomware attack), while a control is a specific action, policy, or procedure you implement to mitigate that risk (e.g., maintaining regular data backups). In short, risks are the problems, and controls are the solutions. Your controls library is an inventory of your solutions. During a risk assessment, you identify potential risks and then map the relevant controls from your library to see how well you are prepared to handle them.

How does a controls library make risk assessments more effective?

A controls library makes risk assessments more effective by providing a ready-made inventory of all security and compliance measures currently in place. This allows you to systematically map your existing controls against identified risks to uncover gaps in your defenses. Instead of guessing, you can conduct a data-driven analysis. For any given risk, you can see exactly which controls are supposed to mitigate it. If a critical risk has few or no corresponding controls, you have a clear, justifiable reason to request resources for improvement.

How often should a GRC controls library be updated?

A GRC controls library should be treated as a living document and reviewed at least quarterly. Major updates are necessary whenever new regulations are introduced, business objectives change, or new systems are implemented. Regular updates ensure the library remains an accurate reflection of your control environment. Schedule periodic reviews with control owners to validate implementation statuses and adjust for any changes in the threat landscape.
