📖 What is Gap Analysis?
Gap Analysis is a technique used to compare the current state of an information security program against a desired target state or industry standard. The resulting 'gap' identifies the specific controls or processes that need to be implemented.
"This is a foundational step in program development. You cannot build a roadmap for security improvement without first performing a gap analysis against a framework like ISO 27001."

🔑 What are the Key Concepts of Gap Analysis?
- ▸ The process involves documenting the 'As-Is' state and defining the 'To-Be' state based on business goals, regulatory requirements, or industry best practices.
- ▸ Utilizing industry standards like ISO 27001 or NIST CSF provides a structured benchmark to objectively measure the maturity and effectiveness of existing security controls.
- ▸ The primary output is a deficiency list that informs the security roadmap, allowing the CISM to prioritize remediation efforts and allocate resources efficiently.
- ▸ Gaps are not treated equally; they are prioritized based on the level of risk they introduce to the organization's most critical business processes.
- ▸ Maturity models are often employed to quantify the gap, moving from an ad-hoc state to a managed, measurable, and optimized security posture.
🎯 How does Gap Analysis appear on the CISM Exam?
You may be asked to identify the first step a CISM should take when tasked with aligning an existing security program with a newly adopted regulatory framework to ensure full compliance.
A scenario might describe a company that has implemented various security tools but lacks a cohesive strategy; you must identify gap analysis as the primary tool to find missing controls.
Expect questions where you must distinguish between a gap analysis and a risk assessment, specifically focusing on the comparison to a standard versus the identification of threats and vulnerabilities.
❓ Frequently Asked Questions
What is the difference between a gap analysis and a risk assessment?
Gap analysis compares the current state to a specific standard or target state, whereas risk assessment identifies threats and vulnerabilities to determine the likelihood and impact of a potential security event.
How does a gap analysis directly influence the security roadmap?
The identified gaps serve as the requirements for the roadmap. By prioritizing these gaps based on risk and business impact, the CISM can schedule projects and allocate budget effectively.
