Solution

Conducting regular security audits and assessments is the most effective method for ensuring compliance with regulations such as GDPR or HIPAA. Audits systematically evaluate the organization’s security posture, ensuring that all processes, policies, and technologies meet compliance standards. Audits can identify vulnerabilities, gaps in security controls, and areas of non-compliance before they are exploited, thus minimizing the risk of data breaches. Regular assessments also ensure that the organization remains compliant as regulations evolve and new threats emerge. Why Other Options are Incorrect: A) Implementing strong password policies: Strong passwords are essential but are not sufficient to ensure compliance with complex privacy regulations. B) Encrypting data at rest and in transit: While encryption is crucial for protecting data, compliance requires a broader range of controls, including documentation, processes, and incident response. D) Using multi-factor authentication (MFA): MFA reduces unauthorized access but does not address all aspects of regulatory compliance or broader security concerns. E) Training employees on data protection best practices: Training is important but must be combined with formal audits to verify that policies are being followed.
