Which statement about logging and log files is true?

Log files play a crucial role in demonstrating compliance with various regulations, such as GDPR, HIPAA, and PCI DSS. These regulations often require organizations to maintain extensive records of access to and changes in sensitive data. By keeping comprehensive logs, organizations can provide evidence of their adherence to these standards during audits or assessments by regulatory bodies. Log files typically contain information about user interactions, system activities, and security events, which are essential for validating compliance.

In contrast, other statements do not accurately capture the full purpose and utility of log files. While log files can be utilized internally for monitoring and troubleshooting, they are not restricted to internal use only; they also serve compliance and security auditing purposes. Furthermore, log files are not inherently deleted after a specific period; retention policies can vary based on organizational needs and regulatory requirements. Lastly, log files are indeed beneficial for audits, as they provide necessary evidence to assess security and compliance practices.
