To ensure relevancy, an organization's security policies and procedures should be reviewed at least:

Reviewing an organization's security policies and procedures at least once a year aligns with best practices in risk management and compliance. This frequency is essential to ensure that the policies remain relevant to the evolving security landscape, emerging threats, and changes in organizational structure or operations. Annual reviews provide an opportunity to assess the effectiveness of existing security measures, make necessary updates, and ensure compliance with legal and regulatory requirements that may have changed over time.

Additionally, considering the pace at which technology and cybersecurity threats evolve, annual reviews help organizations stay proactive rather than reactive. This frequency allows for timely updates that can mitigate risks associated with outdated or ineffective policies. Regular evaluations support continuous improvement in the organization's security posture, safeguarding sensitive data and maintaining stakeholder trust.

In contrast, reviewing security policies at less frequent intervals, such as every two, five years, or even six months, may lead to lapses in security measures and heightened risk exposure during periods without updates. Annual reviews strike an appropriate balance between thoroughness and adaptability to changing circumstances in the security realm.
