Security auditing is the systematic evaluation of an organization's information systems to assess the effectiveness of security controls, identify vulnerabilities, and verify compliance with regulatory standards and internal policies. Auditors analyze configurations, access controls, logging practices, and incident response procedures to determine risk exposure.
This skill is essential in industries handling sensitive data, such as finance, healthcare, government, and technology. Professionals with expertise in security auditing support risk management by providing actionable findings and recommendations to strengthen security postures. Common audit types include network security audits, application security reviews, and compliance audits for frameworks like ISO 27001, SOC 2, HIPAA, and GDPR.
