ClassNK publishes its Cybersecurity Approach

ClassNK has released its Cybersecurity Approach, which outlines its basic approach to ensuring onboard cybersecurity for ships.

{mprestriction ids="1,2"}The ClassNK Cybersecurity Approach was compiled to help stakeholders deal with the increasing threat of cyber-attack. It provides guidance on how to take appropriate measures for onboard cybersecurity and is based on trends in international institutions and maritime bodies.

ClassNK suggests that navigational safety is regarded the most important goal of onboard cybersecurity. Both operational and information technology systems should be cybersecure in order to ensure their availability and support the operation of ships.To mitigate cyber risks in both IT and operations, ClassNK proposes measures based on a balanced combination of physical, technical, and organisational approaches, such as designing ships and onboard equipment with security focussed on each element of the ship, for instance by design or constructing management systems during service.

ClassNK will classify cybersecurity controls into different layers, and clarify what each stakeholder should do for each layer by adopting requirements from the existing standards on cybersecurity that are considered applicable to ships. In light of the increased use of IT for the operation of ships and international trends in cybersecurity, ClassNK will analyse the latest information with experts and propose current best practices in cybersecurity controls for ships.

Based on these concepts, ClassNK will continually publish guidelines and standards that specify the parties responsible for implementing cybersecurity controls and the details thereof as part of the "ClassNK Cyber Security Series".

As part of the ClassNK Cyber Security Series, ClassNK will also be releasing the Cybersecurity Management System for Ships that targets ship management, and Software Security Guidelines that target ship software in the near future.

In addition, ClassNK has released Guidelines for Designing Cyber Security Onboard Ships for newbuilding designs targeting shipyards and ship-building owners as the first part of the ClassNK Cyber Security Series. The guidelines include security measures from the NIST SP800-53(*) compiled for the US Government that can apply to ships, and the latest IACS recommendations.

The guidelines which include the ClassNK Cyber Security Approach are available to download free of charge via ClassNK’s website www.classnk.com for those who have registered for free with the ClassNK “My Page” service.

  • Gaining visibility of your onboard systems: you can’t secure something you can’t see

    By Ken Woghiren, Chief Technology Officer, CyberOwl

    Monitoring is the backbone of good cyber risk management. If you don’t know what assets you have and can’t see what is happening to those assets, then you can’t respond properly if they are under attack. But some fleet operators struggle to justify the budget until they better understand the volume and severity of cyber risks they’re exposed to - a vicious cycle, where lack of visibility leads to lack of action. Shipping IT managers can break out of this vicious cycle and implement some basic cybersecurity monitoring. This article sets out some practical guidance to get started. The rationale is clear: even some basic monitoring and a response plan makes your vessel significantly harder to attack than the next one.

  • We hacked a ship. The owner is liable.

    Author: Ewan Robinson, director of maritime communications and solutions provider Yangosat. 

    We hacked a ship. The Owner is Liable.

    Well, we hacked the communications system of the ship. Technically we have been doing this for a few years.

    This time we did it like a “bad guy” would.

    We got into the vessel, belonging to a multinational company, and found out everything possible about the system, the setup, the manufacturers information.

    This is a very specialised vessel that was alongside in the capitol city of a major European country, carrying out cargo discharge.

    We could have broken the system so badly, the vessel would have been back to Sat-C and flag signals.

    Any information going through that satcomm would have been able to be collected, checked and used.

    As we are Ethical Hackers, we are obliged to act in certain ways. One of them is that we have to tell everyone involved if we did something during testing.

    We did. Well, we tried to.

    The Owners operators, when we finally managed to get someone in the overworked operations department to listen, didn’t care and ignored us.

    The manufacturers didn’t even bother to respond.

    All of the test was documented, peer reviewed and otherwise substantiated by trusted persons.

    The lawyers are going to have a field day and be very happy.

    Ship owners are not.

    Owners and operators are being badly supported and advised by these super providers, who use third party engineers, or poorly trained engineers, and leave systems in an exposed state. Equipment manufacturers and developers are so guilty of poor techniques and security that using “industry best practice” is a total contradiction.

    Lawyers, P&I and Class are going to be so busy refusing claims in the event of a cyber incident, that the poor owners are not going to know where to turn.

    Owners are forced into accepting sub-standard equipment. This equipment cannot be made secure in its current format, and yet the manufacturers and developers, fail to update and secure them.

    The providers supply this equipment, along with the bandwidth and engineers who install them, and then incorrectly configure and allow public access to them. The Owner is still liable.

    So how were they failed?

    We have been presenting at various conferences over the last few years, highlighting how exposed we are as an industry to ‘hackers’ and bad actors.

    It normally consisted of a prepared victim vessel, using a system that had been poorly configured by the provider, or the providers appointed/trained engineer, and accessing the equipment onboard, normally the antenna or satcomm system. It’s a quick way to display to an audience just how much we are ‘displaying publicly’.

    recently someone asked “what could someone actually do?”

    A relevant question we thought, so we tested to see what we could actually do.

    As a basic attack, an intruder could lock out all the users from accessing the equipment. They could turn off the satcom, or prevent systems and users onboard gaining access to the internet or to systems onshore or stop onshore reaching the vessel.

    OK, so this is annoying and disruptive, costing from a few hundreds to several tens or hundreds  of thousands if the charterer deems “off hire” status due to lack of communications.

    Well, that’s quite expensive, potentially.

    But what can we learn from the systems we can get at?

    A lot.

    Given the amount of systems that are exposed to the internet, with poor configuration, it is relatively easy to find a ‘victim’, and to maximise the information gained by using the tools available and exposed by the simplest of mistakes.

    Default admin passwords.

    There is a need for it, but no excuse for it.

     Service Providers, who manage several thousands of vessels, still use engineers who leave default admin usernames and passwords.

     So, it’s a fault on one vessel, but it cant really hurt can it?

    It can. And it does.

     Our target vessel was found.

    That took 7 minutes to locate.

    It belonged to a very large multinational corporation. The default username and password was still in effect on the VSAT system.

    Access was made to the administration area, so all usernames and passwords could be changed. Also available was access to the system by FTP. Even if this had not already been enabled, as we were in the Admin area, we could have enabled it.

     This is where major security flaw #1 was found. The FTP access gave access to the entire operating system of the device, not just the FTP area.

    Major security flaw #2 was putting a text file in every folder with a map of the entire structure of the operating system.

    This allowed for finding and copying the ‘hidden’ password file to our local machine. It was actually encrypted.

     2 hours later, it wasn’t.

    So now we had all the manufacturers usernames and passwords.

     Now we can access the publicly available machines where they have changed the default admin username and password, by using the manufacturers. They have these so the engineers can always get in. Great for business and support, not so for security.

     The network connections listed in the antenna setup were then investigated.

     The VSAT Modem was accessed, again using default connections on SSH, with publicly available usernames and passwords.

    Command line access to the modem was achieved, allowing us to take control and alter the configuration. In effect we could now control the communications in 2 different places.

     Such systemic failures, at the developmental and operational level, are going to have huge issues when Cyber 2021 comes into force next year.

    Class and P&I will be left wondering who to refuse claims and who to sue for negligence when there are events, while the operators are trusting the providers to implement correctly, and the manufacturers and developers are failing at such basic levels, they will likely be left with the legal responsibility in the first instance.

    The lesson of life in todays marine communications environment?

    Don’t trust what’s being given to you.

    Unless you have had your own trusted IT check what’s gone before, why would you blindly trust a stranger with your vessels now?

    The Owner is Liable.
