Gap Analysis

What is Gap Analysis?

Gap Analysis is a systematic process of comparing an organization's current security posture against desired standards, frameworks, or best practices to identify deficiencies, vulnerabilities, and areas for improvement. It provides a structured approach to understanding security gaps and prioritizing remediation efforts.

Gap Analysis Process

Phase 1: Planning and Preparation

• Scope definition – Determine analysis boundaries and objectives
• Framework selection – Choose relevant security frameworks
• Stakeholder identification – Identify key personnel and departments
• Resource allocation – Assign personnel and tools for analysis
• Timeline development – Create project schedule and milestones

Phase 2: Current State Assessment

• Documentation review – Examine existing policies and procedures
• Technical assessment – Evaluate current security controls
• Process evaluation – Review operational security processes
• Compliance audit – Assess current compliance status
• Risk evaluation – Identify existing security risks

Phase 3: Desired State Definition

• Framework mapping – Map requirements to chosen frameworks
• Best practice identification – Identify industry best practices
• Regulatory requirements – Document compliance requirements
• Business objectives – Align with organizational goals
• Risk tolerance – Define acceptable risk levels

Phase 4: Gap Identification

• Control comparison – Compare current vs. desired controls
• Process gaps – Identify missing or inadequate processes
• Technology gaps – Identify missing or outdated technologies
• Policy gaps – Identify missing or inadequate policies
• Compliance gaps – Identify regulatory compliance deficiencies

Phase 5: Analysis and Prioritization

• Risk assessment – Evaluate impact and likelihood of gaps
• Resource analysis – Assess required resources for remediation
• Cost-benefit analysis – Evaluate remediation costs vs. benefits
• Timeline planning – Develop remediation timeline
• Dependency mapping – Identify interdependencies between gaps
