Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

Introduction

This document has been prepared to provide requirements for identification and assessment of cyber

hazards and risks affecting the safe and environmentally sound operation of ships throughout their

operational life. This document provides specifications for procedures designed to be included or

referenced in the company safety management system (SMS) in order to support effective cyber risk

[1]

management as defined in MSC-FAL.1/Circ.3 on Guidelines for Maritime Cyber Risk Management , as

well as any additional requirements of the company or other identified stakeholder.

Operational technology (OT) includes devices, sensors, software and associated networking that

monitor and control onboard systems required to safely and efficiently operate the ship. OT includes,

but is not limited to, navigation, main and auxiliary machinery, propulsion management and cargo

management systems.

The risks associated with OT differ from those associated with information technology (IT). In general,

the risks associated with OT have the potential for physical impacts affecting the safety of the ship,

the personnel and cargo onboard, and the marine environment. The risks associated with IT generally

relate to business and other non-physical impacts which are not safety-critical. Where IT and OT

systems are integrated for particular functions, there is a potential for IT to contribute to safety-critical

impacts.

The information security management system (ISMS) recommended by ISO/IEC 27000 addresses

the preservation of the confidentiality, integrity and availability (CIA) of information and data stored

and processed by IT systems. This document uses CIA but focuses on risks associated with the loss of

availability or integrity of OT systems and data which are necessary for the safe and environmentally

sound operation of a ship.
[3]

The objective of the company security management system (SMS) required by SOLAS chapter IX and

[4]

the ISM Code is to provide a safe working environment by establishing appropriate safe practices and

procedures based on an assessment of all identified risks to the ship, personnel and the environment.

The loss of availability or integrity of safety critical systems and data, and disruption of safety related

operational technology (OT) is expected to have physical consequences for the safe operation of ships

and prevention of pollution. Consequently, it is essential that cyber risk management be incorporated

into the company’s overall approach to safety management and compliance with the requirements

[5]

of SOLAS chapter IX and the ISM Code, and as required by resolution MSC.428(98) . The IMO has

recognized that aspects of cyber risk management, including physical security aspects of cyber

[6]

security, should be addressed in ship security plans under the ISPS Code ; however, this should not

be considered as requiring a company to establish a separate cyber security management system

operating in parallel with the company safety management system.
