SSO Security Equipment & Training 3 — Questions and Answers
Question 1: What does the term 'layered security' mean in the context of shipboard security equipment deployment?
- Installing equipment on multiple decks of the vessel
- Using multiple overlapping security measures so that failure of one does not compromise overall security (Correct answer)
- Encrypting all security communications in multiple layers
- Assigning different security equipment to different watch layers
Correct answer: Using multiple overlapping security measures so that failure of one does not compromise overall security
Layered security means deploying overlapping controls — physical barriers, detection systems, surveillance, and access controls — so no single point of failure defeats the entire security posture.
Question 2: Razor wire or electric fence installed along a ship's railings is classified as which type of security measure?
- Detection measure
- Deterrence and delay measure (Correct answer)
- Response measure
- Communication measure
Correct answer: Deterrence and delay measure
Physical barriers like razor wire deter boarding attempts and delay intruders, buying time for the crew to respond — they are classified as deterrence and delay measures.
Question 3: Which international regulation mandates that certain ships carry a functioning Ship Security Alert System?
- MARPOL Annex I
- SOLAS Chapter XI-2 (Correct answer)
- ISM Code Regulation 12
- STCW Convention Chapter VI
Correct answer: SOLAS Chapter XI-2
SOLAS Chapter XI-2, which incorporates the ISPS Code, mandates that ships carry and maintain a functioning SSAS to transmit covert security alerts.
Question 4: A water cannon (fire hose used as a security measure) is best employed against which type of threat?
- Stowaways already aboard
- Small craft attempting to come alongside or board (Correct answer)
- Cyber intrusions targeting the ship's IT systems
- Smuggling of contraband in cargo containers
Correct answer: Small craft attempting to come alongside or board
Water cannons create a physical deterrent against small craft approaching the vessel and can repel boarding attempts without lethal force.
Question 5: What is the recommended minimum number of personnel who should know the location and operation of each SSAS activation point?
- Only the master
- Only the SSO
- The master and at least one other designated officer (Correct answer)
- All crew members
Correct answer: The master and at least one other designated officer
Best practice requires that the master and at least one other designated officer know every SSAS activation point location and operation to ensure activation capability if one person is incapacitated.
Question 6: A portable two-way radio used for security communications aboard a ship should primarily operate on which frequency band to ensure reliability in a maritime environment?
- AM (amplitude modulation) band
- UHF or VHF band (Correct answer)
- Shortwave HF band only
- Satellite frequency band
Correct answer: UHF or VHF band
UHF and VHF radios provide reliable short-range communications in the maritime environment and are the standard for shipboard security coordination.
Question 7: When conducting a post-incident review of CCTV footage related to a security breach, what is the SSO's primary obligation regarding that footage?
- Delete the footage after reviewing it to protect crew privacy
- Preserve and secure the footage as potential evidence for authorities (Correct answer)
- Overwrite the footage with the next 24 hours of recording as normal
- Share the footage publicly to warn other vessels
Correct answer: Preserve and secure the footage as potential evidence for authorities
CCTV footage of a security incident must be preserved and secured immediately because it constitutes potential evidence required by port state authorities and investigators.
