How often should configurations ideally be reviewed for security compliance?

The ideal frequency for reviewing configurations for security compliance is quarterly or semi-annually because this timeframe strikes a balance between ensuring that systems are secured against evolving threats and minimizing the operational burden on IT teams. Regular reviews allow organizations to stay ahead of potential vulnerabilities and make adjustments in their security posture as necessary.

Quarterly or semi-annual reviews provide ample opportunity to implement updates and to assess changes in compliance requirements and security threats without overwhelming resources. Security landscapes change rapidly, so less frequent reviews, such as annually, may leave systems exposed to known vulnerabilities for too long. On the other hand, more frequent reviews, like daily or monthly, can be impractical and may divert attention from other critical areas of security management or operational responsibilities. Thus, targeting a quarterly or semi-annual schedule supports continuous improvement in security posture while remaining manageable for organizations.
