Security Experts Predict Risk To Military Navigation Applications

News

Spirent Communications, provider of mobile network, application, services, and device-test solutions, has warned of the increased likelihood of disruptions this year to a wide variety of civil and military applications relying on global navigation satellite systems (GNSS) "“ GPS, GLONASS, Galileo, and BeiDou. 

The prediction of greater risk from hacking and location spoofing attacks by criminal, state-sponsored, and other adversaries is part of Spirent's annual security forecast for 2017. The forecast also highlights the continued risk of distributed denial of service (DDoS) attacks on Internet of things (IoT) devices and industries, including health care and automotive, that Spirent believes are the prime targets for security threats in the near future.

Last year, Spirent's predictions for 2016 led off with a prescient warning about the increased risk of cyber espionage, which has since been borne out, most notably by news reports of suspected activities by the Russian government to influence the 2016 U.S. presidential election. Also as predicted, in 2016 threats from ransomware, malicious insiders, and compromised IoT devices increased, as did attacks on industrial control systems. For example, FBI sources reported on CNN that losses attributed to ransomware in the U.S. were set to exceed $1 billion by the end of 2016. That number is expected to grow in 2017.

In addition to an increased likelihood of GNSS interference, Spirent's annual security forecast for 2017 predicts an expansion of risks from:

"¢ More frequent DDoS attacks against IoT devices, as evidenced in the last quarter of 2016, when multiple major DDoS attacks surfaced worldwide. The most disruptive attack employed Mirai malware covertly installed on a large number of IoT devices. A number of high-profile websites such as Netflix, AirBnB, Twitter, GitHub, and others were rendered inaccessible. Spirent believes that perpetrators will continue to innovate and find new methods for improving and broadening these type of attacks.

"¢ Threats to IoT security, which are increasing as everything that is connected becomes a potential attack vector, including embedded devices, mobile devices, consumer electronics, connected medical devices, industrial control systems, smart home devices, and more.

"¢ Threats to medical applications, networks, and devices in the health care industry, both the back-office systems on which these facilities run and the medical instruments that provide care to patients. A ransomware infection or data breach could adversely affect patient health and privacy.

"¢ Threats to connected vehicles by malicious attackers, as a greater number of attack vectors are inadvertently created that enable remotely gaining control of critical operational components of the vehicle, including engine, steering, and braking functions in addition to other vehicle systems that communicate through the relatively insecure CAN bus infrastructure.

"With the greater drive towards use of autonomous vehicles, which rely heavily on precision GPS positioning and timing, threats posed by signal spoofing, jamming, time tinkering, and more could result in serious disruptions and worse," said Sameer Dixit, senior director of security consulting at Spirent. 

"The transportation industry is taking this very seriously and already looking at various ways to protect against these threats. Because of this, we see momentum towards improving GNSS security in 2017."

According to an article in Defense One, Timothy Bennett, a science-and-technology program manager at the Department of Homeland Security, has already reported the use of GPS spoofing and jamming equipment by Mexican drug cartels along the border to interfere with the U.S. Customs and Border Protection agency's use of drones to patrol the area. Unlike the larger drones designed to military specifications, the smaller drones used for this purpose are more vulnerable to these kinds of attacks.

Spirent's global network of GPS interference detectors has recorded more than 15,000 interference events since it was deployed in 2015, including a surprisingly high number of unintentional events caused by various forms of interference in the GPS L1 frequency band. A significant number of these unintentional events, which often correlate with transmissions from nearby RF transmitters and telecom equipment, have the potential to interfere with GPS signal reception.

Dixon noted one bright spot on the horizon: the increasing awareness up and down the technology food chain of the importance of security in these systems, and the entry of large, experienced, and security-conscious players into the IoT arena.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
