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...
The secret sauce of quantum computing, which even Einstein called "spooky," is the ability to generate and manipulate quantum bits of data or qubits. Certain computational tasks can be executed exponentially faster on a quantum processor using qubits, than on a classical computer with 1s and 0s. A qubit can attain a third state of superimposition of 1s and 0s simultaneously, encode data into quantum mechanical properties by "entangling" pairs of qubits, manipulate that data and perform huge complex calculations very quickly.
Radio-Frequency Identification (RFID) is a technology commonly used for identification, status administration and management of different objects. It is important for people identification, as it is commonly deployed in the latest biometric passports. It operates in several frequency bands like Low frequency band from 125 kHz to 134 kHz, High frequency band with 13.56MHz working frequency, Ultra-high frequency band with 433 MHz working frequency and 860 - 960 MHz sub-band.
In Ultra-high frequency bands there are two types of RFID systems—Active and Passive.
Active RFID system operates on 433 MHz radio frequency and on 2.4GHz from Extremely High- Frequency Range. It supports...
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...
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...
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...
Getting smart about security in smart systems
Smart used to be something we called people or pets. It wasn't a term one would use to describe one's hairbrush. That is changing, of course, in an era of accelerating digital transformation. Now we have smart homes, smart cities, smart grids, smart refrigerators and, yes, even smart hairbrushes. What's not so smart, though, is the way the cybersecurity and cyber-kinetic security risks of these systems are often overlooked, and with new horizon technologies like 5G, these problems are set to grow exponentially.
Cyber-physical systems and the smartification of our world
Cyber-connected objects have become...
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....
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...
Western publications often picture the People’s Democratic Republic of China (hereafter China) as the world’s chief propagator of cyberattacks. But the picture is much more complex than such broad-brush claims suggest.
Few Westerners realize that China and its neighbours in the Greater China region (Taiwan, Macau and Hong Kong) have, over last few years, became the most technologically advanced region in the world – ahead of the West in the adoption, and in many cases even in the development of advanced technologies.
Countries in the region were always close to the top of the list of victims of cyberattacks. Factors, such...
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...
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...
More than half of the world’s population lives in cities. The UN estimates that by 2050 that proportion will be 68% - more than 6 billion people living in high-density conditions. This raises significant challenges. What is the best way to ensure that human needs are met in a fair and equitable way? How will we face challenges like resource strain, waste and pollution management, traffic congestion and connectivity?
In response to these wicked problems, cities are increasingly relying on smart technologies to foster greater efficiency and sustainable growth. These interventions do not, however, come without their own complications. Just...
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...
