ISM cyber security is coming soon - check your preparedness

The IMO has identified cyber security as a risk to be addressed in safety management systems, and the handling of risks is to be verified in audits from 1 January 2021 onwards. This statutory news summarises experiences so far, provides advice on handling and offers a Quick Check.

SHARE:

Relevant for ship owners and managers as well as yards, design offices and suppliers.

The handling of cyber risk through safety management systems continues to vary. Some Document of Compliance (DoC) holders seem to have a good start, while others have not even started. Investing in time and resources is important to implement an effective system.

DNV GL has developed an SMS Cyber Security Quick Check supporting maritime cyber risk handling through the ISM Code. We recommend all ship owners and DoC holders to perform this check, as it gives an overview of topics that have been addressed in 2020, including:

• Commitment from the top and throughout the organization
• Safety and environmental protection policy addressing cyber security
• Comprehensive cyber risk management to identify threats, assess potential consequences of compromised IT and OT systems, and establish appropriate safeguards
• Measures to cover normal operation and emergency situations
• Roles, tasks and responsibilities for company staff and onboard crew
• Continuous improvement of safety management skills of personnel onshore and on board ships, including preparing for emergencies also in light of cyber security
• Cyber safety and cyber security maintenance of systems and data
• Identification of vulnerabilities and weaknesses as well as continuous execution of improvements

DNV GL has collected valuable information from some of our ISM auditors, and a summary of their feedback is provided below.

Cyber challenges reported by DNV GL auditors: Often difficult to address complicated problems in an easy way so that people can manage them without high technical knowledge of cyber safety and security Insufficient control of subcontracted IT services Focusing on both IT and OT is a challenge Weaknesses in access control, separating networks and effective firewalls Insufficient knowledge and training of crew, internal auditors, and superintendents on cyber security Cyber security risks and safeguards are not always easy to understand, and follow-up is a challenge for many Main advice from our auditors and cyber security experts: Enhance risk and vulnerability assessments, test systems and network integrity with experts and concentrate improvement efforts first and foremost on crew and other staff involved in handling cyber security. Build on existing SMS, roles, responsibilities, tasks, etc. mprove the organizational understanding that success is dependent on support from all involved. nvolve, train and motivate crew, superintendents and auditors and gain commitment from top management. Establish appropriate safeguards for cyber security risks and do not try to prohibit everything. Apply work permits tailored for software and hardware changes in order to manage risks in changes to systems. Train both normal safe operational behaviour as well as drill emergency response, also to cyber security events. Keep it simple and remember the IMO advice that the risk management approach to cyber risks should be resilient and evolve as a natural extension of existing safety and security management practices!

The DNV GL SMS Cyber Security Quick Check is a simple way to facilitate the handling of cyber security and support DoC holders with SMS measures on cyber security that fit their needs.

Recommendations

To be prepared for 2021 audits, consider IMO MSC-FAL.1/Circ.3 and note:

No two organizations are the same, and SMS measures must fit the needs of DoC holders. Companies operating ships with limited cyber-related systems may find MSC-FAL.1/ Circ.3 sufficient, while those with complex cyber-related systems may require a greater level of care and seek additional resources through reputable partners. DNV GL has services and experts ready to help.
