How to Undertake a Cyber Security Gap Analysis

A cyber Security gap analysis is typically conducted to identify the gaps between an organization’s current cybersecurity posture and desired or required security standards. It helps assess the organization’s strengths and weaknesses in terms of cybersecurity controls, policies, procedures, and practices. Here’s an outline of the steps involved in undertaking a cybersecurity gap analysis:

1. Define the Scope: Clearly define the scope of the gap analysis, including the systems, networks, processes, and policies that will be assessed. Identify the relevant cybersecurity standards, frameworks, or regulations that serve as the benchmark for the analysis.
2. Identify the Benchmark: Determine the cybersecurity benchmark against which the organization’s security posture will be compared. This could be an industry-specific standard (e.g., NIST Cybersecurity Framework, ISO 27001), regulatory requirements, best practices, or a combination of these.
3. Gather Information: Collect relevant documentation, policies, procedures, security controls, and other artifacts that describe the organization’s existing cybersecurity practices. This includes cybersecurity policies, incident response plans, network diagrams, system configurations, and relevant security logs.
4. Perform Gap Analysis: Compare the organization’s current state to the benchmark by evaluating the documentation, controls, and practices against the requirements of the chosen standard or framework. Identify the gaps, deficiencies, or areas where the organization falls short of meeting the benchmark.
5. Prioritize and Classify Gaps: Assess the significance and impact of each identified gap. Categorize the gaps based on their severity, urgency, and potential risks to the organization’s cybersecurity. Prioritize the gaps to focus on the most critical areas for improvement.
6. Analyze Root Causes: Investigate the root causes of the identified gaps. Understand why the gaps exist, whether it’s due to insufficient policies, lack of employee awareness, inadequate technical controls, or other factors. This analysis helps in formulating effective remediation strategies.
7. Develop Remediation Plan: Based on the prioritized gaps and root cause analysis, develop a detailed plan for remediating the identified deficiencies. This plan should outline specific actions, timelines, responsible parties, and resource requirements for addressing each gap.
8. Implement Remediation Measures: Execute the remediation plan by implementing the necessary changes, improvements, or enhancements. This may involve updating policies and procedures, implementing new security controls, enhancing employee training programs, or improving technical infrastructure.
9. Test and Validate: After implementing the remediation measures, conduct tests and validations to ensure that the gaps have been effectively addressed. This may include vulnerability assessments, penetration testing, security audits, or other forms of testing to verify the effectiveness of the implemented controls.
10. Monitor and Review: Continuously monitor and review the organization’s cybersecurity posture to identify emerging gaps and evolving risks. Regularly reassess the effectiveness of the implemented measures and make adjustments as necessary to maintain a strong security posture.

It’s important to note that a cyber security gap analysis should be conducted by knowledgeable professionals with expertise in cybersecurity standards, frameworks, and best practices. External cyber security consultants or experts may be engaged to provide an unbiased assessment and guidance throughout the process.
