Business analysts support cybersecurity compliance primarily by ensuring that security and privacy expectations are translated into clear, testable requirements that are built into the solution. This includes eliciting applicable organizational security policies, standards, and control objectives, then mapping them into functional and non-functional requirements such as authentication methods, role-based access, logging and audit trail needs, encryption requirements, session controls, data retention, and segregation of duties. When security policies are reflected in the solution requirements, they become part of the delivery lifecycle: they can be designed, implemented, validated in testing, and verified during acceptance. This creates traceability from policy to requirement to control implementation, which is essential for audits and for demonstrating due diligence.

Option A is typically the responsibility of governance, risk, and compliance functions or internal audit, not the BA. Option C is usually performed by security testing specialists, QA teams, or application security engineers using techniques like SAST, DAST, and penetration testing. Option D is largely an operational management and compliance enforcement function, supported by training, monitoring, and disciplinary processes. The BA's distinct contribution is ensuring policy-driven security controls are captured in requirements and embedded into the solution design and delivery artifacts.
