How often must security assessments be reviewed?

The correct answer highlights the necessity for security assessments to be reviewed at least once every five years or whenever significant changes occur. This timeframe ensures that assessments remain current and effective in addressing potential threats. Reviewing security assessments regularly allows for the evaluation of new vulnerabilities that may arise due to technological advancements, changes in operational procedures, or shifts in the threat landscape.

By mandating reviews in relation to significant changes, the guidelines ensure that assessments are not static; they evolve alongside the operational environment and potential risks. This approach helps organizations maintain robust security measures and ensures compliance with regulations, which often require periodic evaluations to safeguard assets and personnel in the maritime sector.
