During a quarterly security assessment, a security analyst is tasked with reviewing web-server and domain-controller event logs from the previous three months. Management wants to understand the security value of performing this review on a routine basis to justify resource allocation. Which primary security benefit should the analyst emphasize?
Identification of unauthorized access attempts and suspicious behavior patterns
Measurement of server response times and application performance
Verification of successful backup completion and restoration capabilities
Confirmation of proper account provisioning and access rights
Regular log reviews allow security teams to detect and investigate suspicious activity, such as repeated failed logins, privilege-escalation events, and other indicators of compromise. By identifying unauthorized access attempts early, an organization can respond before the activity results in data loss or system compromise. Backup validation, performance tuning, and account-provisioning audits may also rely on logs, but those objectives are secondary compared with the core security goal of threat detection.
