Cyber attacks as big a threat to warships as missiles and torpedoes, Navies developing cyber security measures and technologies

An internal US Navy review concluded that the service and its various industry partners are “under cyber siege” from Chinese hackers who are building Beijing’s military capabilities while eroding the US’s advantage, The Wall Street Journal reported in March 2019. Chinese hackers have repeatedly hit the Navy, defense contractors, and even universities that partner with the service. “We are under siege,” a senior Navy official told The Journal. “People think it’s much like a deadly virus – if we don’t do anything, we could die.”


Breaches have been “numerous,” according to the review. While China is identified as the primary threat, hackers from Russia and Iran have also been causing their share of trouble. US  Navy considers that it  faces threats from adversary nations like  Russia, China, Iran, and North Korea, which have developed significant  information warfare capabilities and interested  in exploiting the Navy’s networks to conduct espionage operations, either by stealing information and technical data on fleet operations or preventing the Navy from taking advantage.


Earlier in 2019 the Journal reported that Chinese hackers have targeted more than two dozen universities in the US and elsewhere in an attempt to steal military secrets, particularly those related to maritime technology.


Secretary of the Navy Richard Spencer launched the recently concluded review in October, warning that “attacks on our networks are not new, but attempts to steal critical information are increasing in both severity and sophistication.” “We must act decisively to fully understand both the nature of these attacks and how to prevent further loss of vital military information,” he added.


Chinese hackers have breached U.S. Navy contractors to steal a raft of information, including missile plans, through what some officials describe as some of the most debilitating cyber campaigns linked to Beijing, the Wall Street Journal reported in Dec 2018. Victims have included contractors of all sizes, with some of the smaller ones struggling to invest in securing their networks, as hackers over the last 18 months have conducted numerous breaches to gather intelligence, sabotage American systems, and steal intellectual property, the Journal reported. The Journal’s report was based on information from experts and officials, who said that Navy Secretary Richard Spencer had ordered a review of cybersecurity weaknesses that led to an initial assessment validating concerns and laying groundwork for a response by the Navy. Officials in the Navy called the breaches troubling and unacceptable, the Journal reported.


Another Cyber threat is  spoofing and jamming attacks on  the  position, navigation, and timing (PNT) systems, that are dependent on Global Positioning System (GPS) satellite constellation.  GPS spoofing  attempts to manipulate a GPS receiver by broadcasting counterfeit signals remains the most likely attack method it due to its simplicity. This form of attack involves overpowering the receiver by broadcasting signals that are synchronized with the legitimate signals detected by it, thereby forcing GPS to provide false information.


In July, 2017  the US Maritime Administration reported  an incident in which at least 20 Russian ships appeared on trackers to be in the same spot 20 miles (32 kilometres) inland, despite being at various positions in the Black Sea. While this initially appeared to be a glitch, experts now suggest that Russia may have been testing a new system for spoofing GPS.


Researchers suspect that Iran used same methods to two United States riverine patrol boats in January 2016 when they unknowingly sailed into Iranian waters and were accused of violating Iran’s territorial integrity. As the Iran’s cyber warfare capabilities are increasing and its relations with US are deteriorating there is increasing threat of Iran using Cyber Warfare against US Navy.


North Korea, a close military partner of Iran, has reportedly used GPS jamming to disrupt air and naval traffic within the demilitarized zone as reported by Ian W. Gray in The Diplomat. The South Korean counter-espionage agency which launched a probe into an alleged hacking attack on a naval warship building firm last month says it believes North Korea may be behind the hack. On 20 April, Hanjin Heavy Industries & Construction Co, the largest naval shipbuilders in South Korea, was hit by a cyber-attack leaving possible classified files exposed.


Cyber warfare has moved to maritime domain. “The risk of cyber attacks against our ships and submarines is as real a threat as traditional weapons such as rockets, missiles and torpedoes,” Royal Navy says. Navies around the world are now developing new cyber security measures and technologies  and carrying out exercises to test the operational effectiveness of warships, submarines and  Marines in responding to cyber incidents that may unfold during a real-life crisis.


IMO has issued MSC-FAL.1/Circ.3 Guidelines on maritime cyber risk management. The guidelines provide high-level recommendations on maritime cyber risk management to safeguard shipping from current and emerging cyber threats and vulnerabilities and include functional elements that support effective cyber risk management.


Cyber Threats in Maritime domain

Ships are increasingly using systems that rely on digitization, integration, and automation. Offensive actors understand the naval reliance on communications, ISR, and visualization technologies, and perceive them as vulnerable to disruption and exploitation. In 2016, the Baltic and International Maritime Council (BIMCO) in their “Guidelines on Cyber Security Onboard Ships,” warned about the vulnerability of Merchant ships from cyber attacks due to their increased networking and automation systems onboard. Navies are moving to network centric systems in which all the sensors weapons and  command and control on ships, aircraft, submarines, and unmanned vehicles are ‘networked’ , which also enhances vulnerability.


Cruise ships could be sunk by cyber terrorists, official Government guidance has warned in a drive to improve protections from online attacks. Vessels could be vulnerable to “kidnap, piracy, fraud [and] theft of cargo” if their computer systems are compromised, the Transport Department said. At worse a cyber-hack could result in “risk to life and/or the loss of the ship”, the industry was also told.


The concern is that hackers could distort mapping equipment or the ship’s controls, causing it to hit another vessel or run aground.  The dire warnings were made in a “Cyber Security for Ships” code of practice, written by the Institution of Engineering and Technology and distributed by Whitehall.


Overall, the Navy faces the same technological challenges confronting the rest of the Defense Department and even the world at large, declares Vice Adm. Mike Gilday, USN, commander, U.S. Fleet Cyber Command/U.S. 10th Fleet. One of the Navy’s top concerns is that an adversary would deny the fleet its cyber capabilities in a conflict. The service is working to enable its forces to operate in this kind of denied environment, but Adm. Gilday emphasizes that this does not represent an abandonment of cyber as a key warfighting tool. “Cyber is absolutely a key enabler, particularly early in a fight when we want to increase the fog and friction of war and place ourselves in a position of advantage against an adversary,” he declares. “Cyber is absolutely, positively part of how we have to fight in the future—and how we have to shape that environment right from the onset.”


Post  Snowden/NSA disclosure another serious type of threat  that has potential to cause irreparable harm to the Navy’s interests is  the insider threat. Presidential Executive Order 13587, signed in 2011 to improve federal classified network security, further defines an insider threat as “a person with authorized access who uses that access to harm national security.”


Mr Searle said cyber attack “is a real threat, certainly, it’s something we take very seriously, particularly areas of the combat system, communications systems, power and propulsion control systems. “We put a lot of effort into ensuring the security of those systems from software, from a communications point of view.” The Armed Forces must be able to defend themselves against cyber attacks to ensure their operational capability and also be prepared to carry out cyber attacks themselves to gain an operational advantage.


Naval Dome exposes vessel vulnerabilities to cyber attack

 Naval Dome  exposed  some of the vulnerabilities with a series of cyber penetration tests on systems in common use aboard tankers, containerships, superyachts and cruiseships, revealing with startling simplicity the ease with which hackers can access and over-ride ship critical systems. With the permission and under the supervision of system manufacturers and owners, Naval Dome’s cyber engineering team hacked into live, in-operation systems used to control a ships’ navigation, radar, engines, pumps and machinery.

While the test ships and their systems were not in any danger, Naval Dome was able to shift the vessel’s reported position and mislead the radar display. Another attack resulted in machinery being disabled, signals to fuel and ballast pumps being over-ridden and steering gear controls manipulated. Commenting on the first wave of penetration tests on the ship’s ECDIS system, Naval Dome cto Asaf Shefi said: “We succeeded in penetrating the system simply by sending an email to the Captain’s computer.

“We designed the attack to alter the vessel’s position at a critical point during an intended voyage – during night-time passage through a narrow canal. During the attack, the system’s display looked normal, but it was deceiving the Officer of the Watch. The actual situation was completely different to the one on screen. If the vessel had been operational, it would have almost certainly run aground.”
According to the former Head of the Israeli Naval C4I and Cyber Defence Unit, the Naval Dome hack was able to alter draught/water depth details in line with the spurious position data displayed on screen. “The vessel’s crucial parameters – position, heading, depth and speed – were manipulated in a way that the navigation picture made sense and did not arouse suspicion,” he said. “This type of attack can easily penetrate the antivirus and firewalls typically used in the maritime sector.”
Commenting on the ease with which Naval Dome was able to bypass existing cyber security measures, Shefi explained: “The Captain’s computer is regularly connected to the internet through a satellite link, which is used for chart updates and for general logistics updates. Our attacking file was transferred to the ECDIS in the first chart update. The penetration route was not too complicated: the attacking file identified the Disk-On-Key used for update and installed itself. So once the officer had updated the ECDIS, our attack file immediately installed itself on to the system.”


In a second attack, the test ship’s radar was hit. While the radar is widely considered an impregnable, standalone system, Naval Dome’s team used the local Ethernet Switch Interface – which connects the radar to the ECDIS, Bridge Alert System and Voyage Data Recorder – to hack the system.

“The impact of this controlled attack was quite frightening,” said Shefi. “We succeeded in eliminating radar targets, simply deleting them from the screen. At the same time, the system display showed that the radar was working perfectly, including detection thresholds, which were presented on the radar as perfectly normal.”

A third controlled attack was performed on the Machinery Control System (MCS). In this case, Naval Dome’s team chose to penetrate the system using an infected USB stick placed in an inlet/socket. “Once we connected to the vessel’s MCS, the virus file ran itself and started to change the functionality of auxiliary systems. The first target was the ballast system and the effects were startling. The display was presented as perfectly normal, while the valves and pumps were disrupted and stopped working. We could have misled all the auxiliary systems controlled by the MCS, including air-conditioning, generators, fuel systems and more.”

Itai Sela, ceo of the Israel-based company, further noted that the virus infecting ship systems can also be unwittingly transferred by the system manufacturer. “As manufacturers themselves can be targeted, when they take control of onboard computers to carry out diagnostics or perform software upgrades, they can inadvertently open the gate to a cyber attack and infect other PC-based systems onboard the ship.”
“Our solution can prevent this from happening,” he concluded.


Cybersecurity Policy

Navy Secretary Ray Mabus has  called for the implementation of a layered approach to cyber defense and the establishment of a department wide program to tackle insider threats. Navy organizations, including the Marine Corps, “shall implement a defense-in-depth/defense-in-breadth [cybersecurity] strategy to mitigate information security risks throughout the entire life cycle of a system or network,” the memo states.


“The [Department of the Navy] shall establish an integrated set of policies and procedures to deter, detect and mitigate insider threats before damage is done to national security, personnel, resources and/or capabilities,” the memo states. The memo also updates acquisition strategy by calling on officials to make sure cybersecurity is considered at every phase of a system’s development and implementation. The memo also rebrands the DON Information Assurance Program as the DON Cybersecurity Program.

Cybersecurity Measures

Operational commanders, depend on naval networks for command and control, maritime situational awareness, and integrated fires in all phases of conflict or crisis. The availability, integrity, and confidentiality of naval networks and communications systems need to be well protected. A malicious intrusion into naval networks may prove disastrous for own operations. On top networks are required for the logistics, administrative, medical, and training functions, writes Ralph D. Thiele, in Focus on Defense and International Security Game Changer – Cyber Security in the Naval Domain.


Yet, securely operating and defending naval networks is a particular challenge. A key issue has become to reduce ‘attack surfaces’ – i.e. the opportunities for malicious actors to get into naval networks. To this end, network controls include network firewalls, intrusion detection and prevention systems, security information and event management, continuous monitoring, boundary protection, and defence-indepth  functional implementation architecture, anti-virus protection on all host systems, robust vulnerability scanning, and cyber risk management.


Technical cybersecurity applies across the naval network, afloat and ashore, including host level protection with software designed specifically for naval requirements. Information assurance is a top priority in highly networked environments. It requires the coordinated use of multiple security countermeasures to protect the integrity of the information assets. Obviously, it would be more difficult for an opponent to defeat a complex and multi-layered defence system than to penetrate a single barrier. Also, the naval ability to exercise command and control in the presence of a protracted “information blockade” employed by adversaries needs to be assured, especially under heavily contested or denied operational conditions.


The Royal Navy is running its first ever large-scale cyber war games, to protect warships and submarines from cyber attacks. Dubbed Information Warrior 17, the training exercise is designed to ensure the Navy is prepared for the challenges that a new era of warfare could pose, as project director Colonel Dan Cheesman of the Royal Marines explained. Thousands of members of the navy, air force and army will take part in Information Warrior 17, as part of an even bigger Nato training exercise, Joint Warrior, in Scotland. During the exercise, the navy will use artificial intelligence to set up a “ship’s mind”, which will allow warships and submarines to make decisions automatically.


The new Type-26 Global Combat Ship, which is designed to be the workhorse of the Royal Navy when it is built, has been designed to protect its weapons, engines and systems from cyber warfare as reported by Ben Farmer, Defence Correspondent. Geoff Searle, head of the Type-26 programme at BAE Systems, said: “It is an equally important threat to the more traditional threats and one that we take very seriously and design the ship to be confident it can withstand that.”


Automation, a tool for attackers, is key to Navy cyber defense. Adm. Gilday says it is required for protection that goes beyond boundary and point defenses. He calls for greatly increased investment in artificial intelligence and cognitive computing. Artificial intelligence should be leveraged to provide a greater understanding of activities deep inside Navy networks. “We need to move beyond touch labor, in terms of being able to respond rapidly to a threat,” the admiral declares. “We have great detection systems that alert us to known or suspected bads, but the challenge is to be able to quickly identify and respond to an intruder deep inside your networks.”



US Navy Diversifies Ships’ Cyber Systems to Foil Hackers

The Defense Department has said that warships are are broadly vulnerable to cyberattacks. The problem led the Navy to create the RHIMES system, a new effort to protect the electrical and mechanical systems of warships


U.S. Navy has developed a Resilient Hull, Mechanical, and Electrical Security (RHIMES) defense system to protect its ships against hackers who threaten to disable or take control of critical shipboard systems.  Dr. Ryan Craven, a program officer of the Cyber Security and Complex Software Systems Program in the Mathematics Computer and Information Sciences Division of the Office of Naval Research, explained that RHIMES is designed to prevent an attacker from disabling or taking control of programmable logic controllers—the hardware components that interface with physical systems on the ship.


“Some examples of the types of shipboard systems that RHIMES is looking to protect include damage control and firefighting, anchoring, climate control, electric power, hydraulics, steering and engine control,” explained Craven. “It essentially touches all parts of the ship.” The loss of one or more such systems could prove especially devastating in the middle of a naval operation or battle; especially if hackers turn the ship’s systems against itself.


Traditionally, computer security systems protect against previously identified malicious code. When new threats appear, security firms have to update their databases and issue new signatures. Because security companies react to the appearance of new threats, they are always one step behind. Plus, a hacker can make small changes to their virus to avoid being detected by a signature.


“Instead, RHIMES relies on advanced cyber resiliency techniques to introduce diversity and stop entire classes of attacks at once,” Craven said. Most physical controllers have redundant backups in place that have the same core programming, he explained. These backups allow the system to remain operational in the event of a controller failure. But without diversity in their programming, if one gets hacked, they all get hacked.


“Functionally, all of the controllers do the same thing, but RHIMES introduces diversity via a slightly different implementation for each controller’s program,” Craven explained. “In the event of a cyber attack, RHIMES makes it so that a different hack is required to exploit each controller. The same exact exploit can’t be used against more than one controller.”


“The purpose of RHIMES is to enable us to fight through a cyber attack,” said Chief of Naval Research Rear Adm. Mat Winter. “This technology will help the Navy protect its shipboard physical systems, but it may also have important applications to protecting our nation’s physical infrastructure.” “Vulnerabilities exist wherever computing intersects with the physical world, such as in factories, cars and aircraft,” Craven said, “and these vulnerabilities could potentially benefit from the same techniques for cyber resilience.”


IMO Cyber Risk Management

Maritime cyber risk refers to a measure of the extent to which a technology asset could be threatened by a potential circumstance or event, which may result in shipping-related operational, safety or security failures as a consequence of information or systems being corrupted, lost or compromised.


Threats are presented by malicious actions (e.g. hacking or introduction of malware) or the unintended consequences of  benign actions (e.g. software maintenance or user permissions). In general, these actions expose vulnerabilities (e.g. outdated software or ineffective firewalls) or exploit a vulnerability in operational or information technology. Effective cyber risk management should consider both kinds of threat.


Vulnerabilities can result from inadequacies in design, integration and/or maintenance of systems, as well as lapses in cyberdiscipline. In general, where vulnerabilities in operational and/or information technology are exposed or exploited, either directly (e.g. weak passwords leading to unauthorized access) or indirectly (e.g. the absence of network segregation), there can be implications for security and the confidentiality, integrity and availability of information. Additionally, when operational and/or information technology vulnerabilities are exposed or exploited, there can be implications for safety, particularly where critical systems (e.g. bridge navigation or main propulsion systems) are compromised.


Effective cyber risk management should also consider safety and security impacts resulting from the exposure or exploitation of vulnerabilities in information technology systems. This could result from inappropriate connection to operational technology systems or from procedural lapses by operational personnel or third parties, which may compromise these systems (e.g. inappropriate use of removable media such as a memory stick).


Cyber risk management means the process of identifying, analysing, assessing and communicating a cyber-related risk and accepting, avoiding, transferring or mitigating it to an acceptable level, considering costs and benefits of actions taken to stakeholders. The overall goal is to support safe and secure shipping, which is operationally resilient to cyber risks.


These Guidelines present the functional elements that support effective cyber risk management.

.1 Identify: Define personnel roles and responsibilities for cyber risk management and identify the systems, assets, data and capabilities that, when disrupted, pose risks to ship operations.

.2 Protect: Implement risk control processes and measures, and contingency planning to protect against a cyber-event and ensure continuity of shipping  operations.
.3 Detect: Develop and implement activities necessary to detect a cyber-event in a timely manner.
.4 Respond: Develop and implement activities and plans to provide resilience and to restore systems necessary for shipping operations or services impaired due to a cyber-event.
.5 Recover: Identify measures to back-up and restore cyber systems necessary for shipping operations impacted by a cyber-event.
