Bluetooth Cybersecurity
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...
5G SBA IMS MEC Architecture
The interest in 5G and mIoT is exploding. It's exciting to see so many IT and cybersecurity professionals in my network trying to learn more about 5G and related technologies. In addition to my usual articles about the societal impacts of these innovations, I'll start a series of articles introducing key 5G and mIoT technology concepts. Before we move on to technical aspects of 5G security. Let's get started with reviewing the 5G core service-based architecture and learning the first few dozen acronyms, out of approximately a gazillion. The cellular industry loves acronyms. Even more than the cybersecurity industry. 5G architecture is...
Zigbee Security
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...
LoRaWAN IoT Security
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...
Smart Home Wireless Connectivity
In a recent session on smart building cybersecurity, a student cheekily asked me "How did we ever connect anything before 5G?" At that moment I realized I might have been overdoing my 5G cheerleading recently. To atone, here are the key performance and cybersecurity attributes of the most commonly used connectivity technologies in smart home / smart building use cases... And 5G. If you thought that the "traditional" home life is under heavy attack from digitization of media and constant communication, wait until you learn about the Internet of Things (IoT) and Smart Homes. Our most personal spaces - our homes...
5G 3GPP Release Timeline
In a major milestone for 5G, 3GPP finalized the Release 16 in July - its second set of specifications for 5G New Radio (NR) technology. As a second article in my series of 5G 101 articles, this is a good opportunity to review the 3GPP process and major 5G-related technical specification releases. As well as to clarify some misconceptions about the 5G development process. This article provides an overview of what is 3GPP and its importance. It also explains the Releases related to 5G including Release 15, 16 and 17. The focus will be on 3GPP Release 16 and 17. Release...

5G Virtualization
Depending on who you speak to, 5G is either humankind’s greatest imminent blessing or its greatest imminent curse. Still in its infancy, and not yet commercially standardized, this technology has already been the most polarizing advancement we have ever seen in communication. Consumers worldwide are captivated by promises of super-fast download speeds, split-second responsiveness and next-level mobile phone communication, but are divided on the possible sacrifices of privacy and security. Detractors continue to issue condemnations of 5G cellular’s possible health risks. Supporters continue to shake their heads in disbelief. Governments jostle for geopolitical supremacy; 5G is seen as both a proxy...
5G Network Slicing
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,...
IEMI
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...
