Differences between IT and OT systems

Whereas IT systems manage data and support business functions, OT is the hardware and software

that directly monitors/controls physical devices and processes and as such are an integral part of

the ship and must function independently of the IT systems onboard. The systems can, however,

be connected to the IT network for performance monitoring, remote support etc. Such systems

are sometimes referred to as belonging to the Industrial Internet of Things (IIOT).

There may be important differences between who handles the purchase and management of the

OT systems versus IT systems on a ship. IT managers are not usually involved in the purchase of OT

systems and may or may not have a thorough understanding of cyber security. The purchase of such

systems should involve someone, who knows about the impact on the onboard systems but will

most probably only have limited knowledge of software and cyber risk management.

IT covers the spectrum of technologies for information processing, including software, hardware, and

communication technologies. Traditionally OT and IT have been separated, but with the internet, OT

and IT are coming closer as historically stand-alone systems are becoming integrated. Disruption of

the operation of OT systems may impose significant risk to the safety of onboard personnel, cargo,

damage to the marine environment and impede the ship’s operation.


So “Investing on Yourself is the best investment”.

#41 Maritime Cybersecurity

Maritime is one of the oldest industries and lifeblood of the global economy, accounting for the carriage of 90% of world trade. Ships and other vessels may seem like unusual targets for cyberattacks. But with their growing use of industrial control systems (ICS) and satellite communications, hackers have a new playground that’s ripe for attack. In a 2020 Safety at Sea and BIMCO Maritime Cyber Security survey, despite the majority of respondents (77%) viewing cyber-attacks as a high or medium risk to their organizations, few appear to be prepared for the aftermath of such an attack, 64% of respondents said their organization has a business continuity plan in place to follow in the event of a cyber incident, but only 24% claimed it was tested every three months, and only 15% said that it was tested every six to 12 months. Only 42% of respondents said that their organization protects vessels from operational technology (OT) cyber threats, and some respondents went so far as to describe...
