What must be done with logs from various events according to best practices?

Maintaining logs from various events is crucial for security and compliance management, which is why logs should be kept, regularly reviewed, and protected. Keeping the logs allows organizations to track security incidents, monitor system performance, and comply with regulatory requirements. Regular review of these logs enables the identification of anomalies, potential threats, and areas for improvement within security practices. Protection of these logs is essential to ensure their integrity and confidentiality, as they can contain sensitive information that, if compromised, could pose a risk to the organization.

Options suggesting that logs should be deleted after a year minimize their potential value in forensic investigations or compliance audits. Limiting log contents to only administrative actions ignores the broader scope of events that should be monitored for a comprehensive security posture. Lastly, sharing logs with all employees can lead to information overload and security risks, as not all employees need access to this data. Therefore, the best practice is to maintain, review, and protect the logs.
