Which MARSEC level describes baseline security?

Which MARSEC level describes baseline security?

• A. MARSEC I
• B. MARSEC II
• C. MARSEC III
• D. MARSEC IV

Answer: (A)

MARSEC levels indicate the security posture for ships and ports under the ISPS Code. Baseline security corresponds to MARSEC I, meaning normal, standard security measures are in place at all times. This includes routine access control, monitoring, security drills, and adherence to required security plans. When threat levels rise, MARSEC II calls for enhanced measures such as additional inspections and more restricted access, while MARSEC III requires maximum security due to probable or imminent threats. MARSEC IV is not part of the official ISPS MARSEC framework, so the baseline level is MARSEC I.
