The human will to innovate is seemingly relentless. The history of our species is one of continual development, with the last 350 years, in particular, representing staggering technological progress.
The first industrial revolution mechanized production using natural elements like water. The second revolution used electricity to enable mass production; the third used electronics and information technology to automate production. The fourth industrial revolution unfolding all around us is characterized by an exponential growth in data production and the merging of the physical and digital.
Cyber-physical systems (CSPs) like the internet of things (IoT) and industrial control systems (ICS) are capable of...
“Cyber war” is a term that is in recent days used so liberally that people may often wonder if these words are as menacing as they sound or used only as a tool to incite fear as a way to control a society that increasingly depends on technology.
How we prepare and respond to cyber attacks depends on whether we believe we are in cyber war. It influences how we estimate the risks, potential impacts, or insurance premiums. Preparation for and response to cyber war implies government involvement and that might mean handing over the control of our networks to...
Neil Harbisson calls himself a cyborg. Without the antenna implanted in his skull, he would not be able to see colour of any kind. Born with achromatopsia, a condition of total colourblindness that affects 1 in every 30 000 people, Harbisson's physical faculties are augmented by cyber technology to grant him access to a life of greater meaning and satisfaction.
As technological evolution leads to concomitant advances in medical science, we are seeing more and more examples of humans who are integrating devices and sensors into their biological makeup. For some, like those part of the growing "transhumanist" movement, this...
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...
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...
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...
Not even 30 years separate us from the end of the Cold War. Yet, we appear to be witnessing the emergence of a new one, a technology Cold War between the United States and China. This time, instead of a ‘red under the bed’, the US government has declared there is one at the back door. It accuses Chinese technology companies of deliberately building vulnerabilities into their tech, allowing the Chinese to access and control the 5G critical infrastructure, and through it the connected devices and machinery at will.
Headlines are dominated by the case against Huawei, and debate continues...
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...
In 1956, at a workshop on the campus of Dartmouth College, in Hanover, New Hampshire, the field of artificial intelligence (AI) was born. Attendants were buoyant. MIT cognitive scientist Marvin Minsky was quoted as saying, "Within a generation the problem of creating 'artificial intelligence' will substantially be solved."
This prediction turned out to be over zealous, but Minsky and his colleagues believed it wholeheartedly. What, then, is different today? What makes the current dialogue about AI more relevant and believable? How do we know that this is not another case of humans over estimating the development of technology?
For one thing,...
You may have heard, over the last year or two, about the new technological miracle that is the blockchain. It seems that every banker, insurer, manufacturer, artist, lawyer and cybersecurity professional is shouting about blockchain from the highest peak and telling us how it will be used to secure everything against anything for all time, additionally removing those embarrassing blemishes from our skin and freshening our breath at the same time. Clearly some large portion of the blockchain-related content we see in the media is hyperbolic, at best, but it is an important technology nonetheless. Let’s take a look...
In one of those strange inversions of reason, The Internet of Things (IoT) arguably began before the Internet itself. In 1980, a thirsty graduate in Carnegie Mellon University’s computer science department, David Nichols, eventually grew tired of hiking to the local Coca Cola vending machine only to find it empty or stocked entirely with warm cola. So, Nichols connected the machine to a network and wrote a program that updated his colleagues and him on cola stock levels. The first IoT device was born.
Things have moved on somewhat. Today, the world is home to 8 billion connected devices or “things”, with...
The open seas have long attracted those who yearned for adventure. The risk of pitting oneself against a vast and unforgiving sea has tested sailors’ mettle for millennia. It’s not surprising that the maritime industry is one that thrives on facing – and overcoming – risks. But, as technology increasingly dominates it, growing risks exist that the industry dare not ignore.
Its growing effort to increase efficiencies through digitization and automation has made it an inviting target for 21st century pirates whose weapons are not cutlasses, but computers. Vulnerabilities in maritime systems and security practices threaten to inflict huge losses...
The human brain is programmed to keep us safe and secure. Yes, we are separated from the rest of the animal kingdom by our advanced capacities of sense-making and decision-making, but at the core of our grey matter remains some primitive but powerful tech tasked with keeping us alive. If your amygdala senses danger, it makes a split second decision and triggers the fight-or-flight response, flooding your body with hormones like adrenaline that prepare you for battle. This overrides the cortex – the sophisticated part of the brain we rely on for problem-solving and strategic thinking – making it...
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...
The attacker stepped out from behind a hedge in the upper-class suburban neighborhood, being careful to stay in the shadows. Across the street, the last lights shining through the windows of the house had just flickered out. She tugged the bottom of her black hoodie into place and pulled the hood up over her head, casting her face deeper in shadow.
Her target sat in the driveway at the front of the house, a bright red and completely decked out SUV. Glancing up and down the street to ensure no one was looking, she slipped across the street into the...
