PCI DSS Qualified Security Assessor (QSA) Practice Test

Performing critical file comparisons on a weekly basis is recommended because it strikes a balance between security and operational efficiency. Frequent comparisons allow organizations to quickly identify unauthorized changes or anomalies in critical files, which could indicate security breaches, unauthorized access, or other vulnerabilities. A weekly schedule enables teams to regularly monitor and assess the integrity of important files without overwhelming them with an excessive workload that could occur with daily checks.

Additionally, weekly reviews create an ongoing proactive security posture, allowing organizations to respond quickly to any irregularities. This timeframe ensures that while the monitoring process remains rigorous, it is also manageable and continuously effective. Other frequencies might not provide the same level of vigilance; for example, daily checks could lead to complacency or burnout, while monthly or annual checks might allow threats to remain undetected for longer periods, increasing risks to the system's integrity.
