If you've ever been to an expensive restaurant and ordered a familiar dish like, say, lasagna, but received a plate with five different elements arranged in a way that does not at all resemble what you know as lasagna, then you have probably tasted deconstructionism. This approach to cuisine aims to challenge the way our brain makes associations, to break existing patterns of interpretation and, in so doing, to release unrealized potential. If the different elements work together harmoniously, it should be the best lasagna you've ever tasted. So it is with 5G. In principle, the 5th Generation network is deconstructed. Firstly,...

The Wi-Fi represents wireless technology that includes the IEEE 802.11 family of standards (IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11ac, etc.). Within 50m range, it operates in 2.4 GHz and 5GHz frequency bands,. This technology was developed for wireless networking of computer devices and is commonly called WLAN (Wireless Local Area Network), where the communication is realized between wireless routers typically connected to the Internet and other wireless nodes within its range. In correlation with performances of specific IEEE 802.11 standards, different data rates are enabled and their theoretical throughput is 11 Mbps (IEEE 802.11b), 54 Mbps (IEEE...

Bluetooth is short-range wireless communications technology based on the IEEE 802.15.1 protocol. It works in a crowded license free 2.4 GHz frequency band and shares this resource with many other technologies. Bluetooth is the optimal solution for establishing small wireless networks called Piconets, by connecting two Bluetooth devices. One of these nodes is Master that can be connected via Bluetooth link to 7 other Bluetooth devices—Slave nodes in Personal Area Network (PAN). Typical data rates are 1-3 Mbps. The newest versions of Bluetooth is known as Bluetooth Low Energy (BLE) or Bluetooth smart. It is important to note that Bluetooth and BLE...

Zigbee technology introduction Zigbee is wireless PAN (Personal Area Network) technology developed to support automation, machine-to-machine communication, remote control and monitoring of IoT devices. It evolved from IEEE 802.15.4 wireless standard and supported by the ZigBee Alliance. IEEE 802.15.4 standard determines specifications for the physical and data link layer and Zigbee Alliance provides standards from network layer to application layer. While Zigbee determines the contents of the transmitted message, the 802.15.4 standard provides details about the robust radio communication and medium access control. The Zigbee Alliance, as a non-profit association, develops open global Zigbee standard for use in the Internet of Things...

I get accused of focusing too much on 5G as the only future IoT connectivity option. I do write a lot about how 5G will revolutionize our society, become the most critical of critical infrastructures and about security threats with 5G. I see 5G, with its low latency, high bandwidth, network slicing and ubiquitous coverage becoming the foundational capability for mission critical industrial, agricultural, financial, medical, education, energy and transportation, even military and emergency services IoT communication needs. That’s not to say that 5G is the only IoT connectivity option. There are plenty of others. IoT applications have some common requirements...

Ultra high speed, high quality 5G networks are expected to provide the connectivity required for massive IoT adoption, remote robotic surgery as well as instant movie downloads and 3D mobile gaming. The technology boasts incredible reliability and low latency and promises to enable the next industrial revolution and society 5.0. Assuming that 5G policy and regulatory issues are sorted out. However, recent hype generated by mobile operators and false promises inevitably mean that unreasonable early expectations will go unmet. So far, China and Huawei have out-competed Americans in development and deployment of 5G technology. The Trump Administration is keenly aware...

Hyped as the technology that will transform the world, 5G is moving past the buzzword stage with first implementations coming to life in 2019. Nations are racing to 5G with such fervor that it now became one of the hottest hot-button geopolitical issues. With latency as low as 1 ms and speeds of up to 4 Gbps, as well as a wider range of frequency bands and enhanced capacity, 5G will be able to accommodate innovative use cases and much greater numbers of connected devices, driving overall growth for Internet of Things (IoT). In addition to the speed and capacity improvements,...

Don’t let the “5G” in the title confuse you. This post is not only about the telcos’ core networks, but about the 5G security and privacy issues in our (very) near, and very different future that 5G will enable. In the 5G-enabled massive Internet of Things (mIoT) world we’re about to find ourselves in, we are expected to have 1000 devices connected for every person… These devices will be the components of the ‘5G operating system’ for our smart cities, our industry 4.0, our smart homes, smart transportation, smart healthcare, and much more. To enable this future, we will...

Cybersecuring railway systems from potential attackers must become paramount in the digitization that those systems currently undergo. Their cybersecurity is too closely interlinked with the railway safety to leave the door open to disruption. To make matters worse, they are increasingly being targeted. Railway systems have long been critical. Mass transit systems move hundreds of thousands of people throughout urban areas each work day. Freight systems move an estimated 40 tons of freight for every person in the U.S. every year. Imagine the chaos if they were disrupted. These systems have always been challenging to secure. Even urban mass transit systems...

As IoT adoption continues to proliferate, manufactures and adopters are increasingly aware of cybersecurity risks to IoT. Yet, even among the IoT security professionals, one significant potential remote attack vector is often overlooked: intentional electromagnetic interference (IEMI). Electromagnetic interference (EMI) surrounds us – natural causes, such as solar flares and lightning; and man-made sources such as radio and TV broadcasting, radars, microwaves and many others all emit electromagnetic waves that could disrupt operation of electrical and electronic devices. That is, if devices wouldn’t comply with numerous electromagnetic compatibility (EMC) standards which ensure correct operation in common electromagnetic environment and resilience...

While Stuxnet is gone, the world now knows what can be accomplished through cyber-kinetic attacks. As we approach the 10th anniversary of when Stuxnet was (likely) deployed, it is worthwhile to examine the effect it still has on our world. As the world’s first-ever cyberweapon, it opened Pandora’s box. It was the first true cyber-kinetic weapon – and it changed military history and is changing world history, as well. Its impact on the future cannot be overstated. Stuxnet’s beginnings Stuxnet is believed to have been conceived jointly by the U.S. and Israel in 2005 or 2006 to cripple Iran’s nuclear weapon development...

In their growing efforts to increase efficiencies through digitization and automation, railways are becoming increasingly vulnerable to cyber-kinetic attacks as they move away from strictly mechanical systems and bespoke standalone systems to digital, open-platform, standardized equipment built using Commercial Off the Shelf (COTS) components. In addition, the increasing use of networked control and automation systems enable remote access of public and private networks. Finally, the large geographical spread of railway systems, involving multiple providers and even multiple countries, and the vast number of people involved in operating and maintaining those widespread systems offer attackers an almost unlimited number of attack...

As our cities, our transportation, our energy and manufacturing – our everything – increasingly embrace Internet of Things (IoT) and Industrial Controls Systems (ICS), securing its underlying cyber-physical systems (CPS) grows ever more crucial. Yet, even among engineers and cybersecurity specialists, one potential attack trajectory is often overlooked: Intentional Electromagnetic Interference (IEMI). ICS and IoT – digital systems that run today’s modern society – rely on changes in electrical charges flowing through physical equipment. Creating the 1s and 0s of which all digital information is composed requires electronic switching processes in circuits. The current used in this process is not...

The maritime industry faces a not-so-distant future when ships will be completely autonomous, using navigation data that they receive to plot their own courses with only minimal input from shoreside control centers. The efficiencies this could bring are massive, but before this happens, cybersecurity issues must be addressed. Not only are many vessels configured in ways that invite cyberattacks, but security practices also need to be improved before the industry can safely navigate its future. An increasingly digitized maritime industry A fleet of 250 autonomous vessels may launch soon. And that would be only the beginning, according to McKinsey and Co....

Stuxnet was the first true cyber-kinetic weapon, designed to cripple the Iranian – and perhaps also the North Korean – nuclear weapon programs. It succeeded in slowing the Iranian program, although it was discovered before it could deal the program a fatal blow. Its significance goes far beyond what it did. It marks a clear turning point in the military history and cybersecurity. Its developers hoped for a weapon that could destroy strategic targets without civilian damage possible in traditional warfare. Instead, it opened the door to cyberattacks that can deliver widespread disruption to the very civilian populations it was...
