Objectives

• Raise awareness about cyber threats on ships.
• Ensure cyber risks are considered during safety assessments.
• Encourage development and implementation of risk mitigation controls.
• Integrate cyber risk management within existing safety management procedures.
• Foster proactive preparation to detect, respond, and recover from cyber incidents.

Scope and Applicability

MSC.428(98) applies globally to all ships covered under the ISM Code, which includes passenger ships, cargo ships, and tankers operating in international waters. The resolution explicitly states that cyber risk management should be an intrinsic part of the ship's Safety Management System (SMS) and requires regulatory bodies (flag States) to ensure compliance.

Key Components of Ship Cybersecurity Management Under IMO

IMO’s accompanying guidelines, MSC-FAL.1/Circ.3, provide practical recommendations for shipowners and operators, aligning with international cybersecurity frameworks such as the NIST Cybersecurity Framework. The framework revolves around five functional components:

1. Identify

• Conduct comprehensive asset inventories of all IT and OT systems onboard, including navigation equipment, propulsion control, communication devices, and cargo handling systems.
• Define roles and responsibilities for managing cyber risk within the ship’s organizational structure.
• Understand existing vulnerabilities and assess potential impacts of cyber threats on ship operations.

2. Protect

• Establish and implement protection measures to guard systems against cyberattacks.
• Apply access control policies, including role-based system access and strong authentication.
• Maintain timely patch management and updates for software and firmware.
• Employ network segmentation to separate critical OT systems from general IT networks.
• Secure physical access to sensitive equipment and operational controls.

3. Detect

• Develop capabilities to continuously monitor systems for unusual activity or indicators of compromise.
• Implement intrusion detection and prevention systems suited for maritime environments.
• Establish logging mechanisms and review logs regularly for suspicious events.

4. Respond

• Develop incident response plans detailing steps to be taken immediately upon detection of a cyber incident.
• Specify communication protocols, including notifying port authorities, flag states, and company security teams.
• Contain incidents to prevent spread or escalation.

5. Recover

• Include disaster recovery processes to restore affected systems to operational condition.
• Maintain secure backups of critical data and configurations.
• Evaluate post-incident lessons learned to improve cyber resilience.

Challenges and Considerations for Chennai Fleet Operators
