A Tale of Sea and Sky: On the Security of Maritime VSAT Communications Pavur et al. 2020Very Small Aperture Terminals (VSAT) have revolutionized maritime operations. However, the security dimensions of maritime VSAT services are not well understood. Historically, high equipment costs have acted as a barrier to entry for both researchers and attackers. In this paper we demonstrate a substantial change in threat model, proving practical attacks against maritime VSAT networks with less than $400 of widely-available television equipment. This is achieved through GSExtract, a purpose-built forensic tool which enables the extraction of IPtraffic from highly corrupted VSAT data streams.

The Guidelines on Cyber Security onboard Ships (v3) BIMCO et al. 2018As technology continues to develop, information technology (IT) and operational technology (OT) onboard ships are increasingly being networked together – and more frequently connected to the worldwide web. This brings the greater risk of unauthorised access or malicious attacks to ships’ systems and networks. Risks may also occur from personnel having access to the systems onboard, for example by introducing malware via removable media. Relevant personnel should have training in identifying the typical modus operandi of cyber attacks. The safety, environmental and commercial consequences of not being prepared for a cyber incident may be significant. Responding to the increased cyber threat, a group of international shipping organisations, with support from a wide range of stakeholders, have developed these guidelines, which are designed to assist companies develop resilient approaches to cyber security onboard ships. Approaches to cyber security will be company- and ship-specific, but should be guided by appropriate standards and the requirements of relevant national regulations. The Guidelines provide a risk-based approach to identifying and responding to cyber threats.

Cyber Security Issues In Navigation Systems Of Marine Vessels From A Control Perspective Hassani et al. 2017Autonomous marine vessels are the way forward to revolutionize maritime operations. However, the safety and success of autonomous missions depend critically on the availability of a reliable positioning system and time information generated using global positioning system (GPS) data. GPS data are further used for guidance, navigation, and control (GNC) of vehicles. At a mission planning level GPS data are commonly assumed to be reliable. From this perspective, this article aims to highlight the perils of maritime navigation attacks, showing the need for the enhancement of standards and security measures to intercept any serious threats to marine vessels emanating from cyber attacks and GPS spoofing. To this end, we consider a case where a cyber attacker blocks the real GPS signals and dupes the GPS antennas on board the marine vehicle with fake signals. Using the Nomoto model for the steering dynamics of a marine vesseland exploiting tools from linear control theory we show analytically, and verify using numerical simulations, that it is possible to influence the state variables of the marine vessel by manipulating the compromised GPS data.

Cyber security in the oil and gas industry based on IEC 62443 (DNVGL-RP-G108) DNV-GL 2017Industrial automation and control systems (IACS) in oil and gas installations are vulnerable to cyber security incidents. As a result, countermeasures must be in place, and the facility operator must be confident that these countermeasures are sufficient and correctly performed. The risk must be acceptable for all systems including existing and possibly obsolete systems. Due to the high number of packages and systems in the packages, a standard based approach is required. Such standards for industrial automation and control systems are evolving, and the IEC 62443 standard is emerging as the preferred approach for many. The challenges are that this is a generic standard for all industrial components and that it is not finalized yet. Verifying conformance to the entire set of the IEC 62443 series of standards is very costly, and some parts may be irrelevant to certain industries. The standard also refers to security levels (SL), but it may be difficult to define the correct target for the different systems. Currently the standard defines what to do, but does not fully detail how to do it. To overcome these challenges, this recommended practice for implementing IEC 62443 (3-2, 3-3 and 2-4) in the oil and gas sector was produced based on a joint industry project (JIP) with participation from ABB, DNV GL, Emerson, Honeywell, Kongsberg Maritime, Lundin Norway, Petroleum Safety Authority (PSA) Norway, Shell Norway, Siemens, Statoil and Woodside Energy. The purpose of this JIP was to define a common and practical approach on how to secure industrial automation and control systems (IACS) in the oil and gas sector. The recommended practice intends to follow the regulatory requirements defined by PSA for the Norwegian continental shelf and by Health and Safety Executive (HSE) for the UK oil Sector.

Cyber-enabled ships Lloyd’s Register 2016Information and communications technology (ICT) is revolutionising shipping, bringing with it a new era – the ‘cyber-enabled’ ship. Today’s leading manufacturers and ship operators want to innovate using the latest ICT systems, going beyond traditional engineering to create ships with enhanced monitoring, communication and connection capabilities – ships that can be accessed by remote onshore services, anytime and anywhere. ICT systems have the potential to enhance safety, reliability and business performance, but there are numerous risks that need to be identified, understood and mitigated to make sure that technologies are safely integrated into ship design and operations. The marine industry faces complex and serious challenges in order to achieve the full benefits of using ICT. Because a cyber-enabled ship consists of multiple, interconnected systems, and because of the rapid pace of technology development, assuring that a cyber-enabled ship will be safe cannot be prescriptive, and cannot rely on knowledge gained from previous systems. Instead, it requires a ‘total systems’ approach – one that takes account of all the different systems on board and on shore, how they are designed and installed, how they connect and how they will be managed. This is the approach that Lloyd’s Register (LR) takes, applying a non-prescriptive, risk-based process from the earliest concept stage, through on board integration, to operation – one that is based on our extensive experience of system design and installation on board ships and other marine platforms. As a trusted provider of safety assurance to the marine industry, LR is ready to help all stakeholders in the cyber-enabled ship market ensure that ICT is deployed safely.

Cybersecurity Implementation For The Marine And Offshore Industries American Bureau of Shipping 2016 (updated 2018)In the maritime world, safety and security are closely linked. The mission of ABS is to serve the public interest as well as the needs of our members and clients by promoting the security of life and property, and preserving the natural environment. For over 150 years, ABS has devoted its energies to promoting safe and efficient commerce by sea through the development and application of industry consensus standards. Initially, the emphasis was on safety, and ABS applied its technology and knowledge to maintain safety through prevention of accidents caused by the forces of nature and human error. While the science of those causes is very complex and is continually being improved, they are amenable to analysis, understanding and prediction. Through the dedication and diligence of everyone in the maritime industries, the safety record of shipping has steadily improved through the years. Cybersecurity introduces an additional element into the safety equation: security against deliberate actions intended to cause harm. Security has always been a concern with naval ships, and the military routinely exercise precautions to maintain the security of their ships and offshore assets. Commercial vessels routinely employ special security measures under certain circumstances to prevent theft, piracy, smuggling or stowaways. Those crimes are usually economically motivated, where destruction is not the goal. Acts of terror are usually politically motivated, and ships and offshore assets are prime targets because of their mobility and high potential for causing extensive damage to life, property, the environment, and the transportation and economic infrastructure. The maritime community has come to the realization that ships and offshore assets must be made less vulnerable to security threats, both at sea and while in port. Perpetrators of such acts have moved toward cyber-attacks for similar purposes. Exposure to these threats has become pervasive due to the exponential growth of automation methods - and increasingly, autonomy - that has penetrated nearly all aspects of shipboard and offshore asset systems. Because these systems control multiple aspects of asset, ship or platform operations, they become integral parts of system and operational safety. ABS supports the marine and offshore communities by developing the standard for marine and offshore cybersecurity, developing new methods and leading industry with best practices in a commitment to safety and security of life and property and preservation of the environment. Cybersecurity refers to the security of information networks and control systems and the equipment and systems that communicate, store and act on data. Cybersecurity encompasses systems, ships and offshore assets, but includes third parties - subcontractors, technicians, suppliers - and external components such as sensors and analytic systems that interface with networks and data systems. This includes human interaction of crews and other Company personnel, customers and potential threat players. In such a dynamic system, cybersecurity is an evolving set of capabilities inside the Company, developing and adapting as technology and threats evolve.
