BY VARAIDZO MUDEWAIRI JOURNALISTS have been urged to protect themselves against digital surveillance threats after the country passed cyber security legislation. A statement by Fesmedia Africa yesterday said a survival toolkit has been developed in response to growing digital surveillance threats, and passing of cyber security laws by governments and other people that track and monitor journalists in order to muzzle them from carrying out their work. Fesmedia Africa said some of the countries that have passed cyber security legislation include Botswana, Zambia and Zimbabwe. “They have acquired sophisticated tools developed by an Israeli company, which they use to monitor the behaviour of citizens online,” Fesmedia Africa said. They said the affected journalists should report to international and local organisations for protection from surveillance. “A journalist, who is subjected to surveillance, or suspects being subjected to such, should notify these international support structures for journalists. They are very instrumental at documenting such cases, making them known through existing networks and exposing blatant abuse of surveillance especially by state and quasi- state actors. “Surveilled journalists should inform local organisations within their countries who work in conjunction with global organisers.” Fesmedia Africa said that journalism often takes place in contested environments, and the very act of exposing the truth can upset powerful people. “Journalists should set up dummy emails, set up investigation accounts, use VPN and browsers to keep themselves and their sources safe.” Fesmedia Africa said in 2018 the UN Passed the Right to Privacy in the Digital Age instrument which recognises the right to privacy and the need to limit surveillance. They also said that the Declaration of Principles...
The ‘!’ notation is the factorial. As you might see, for non-negative integer x, it is calculated as the multiplication of all numbers up to x, for example: 2.2. The binomial density funtion (PMF) Now, we are ready to define the binomial density function as a probability of obtaining m successes in N Bernoulli trails: So, the binomial distribution is a discrete probability distribution of the number of successes (m) in a sequence of N independent repetitions of a given experiment, which asks yes-no (success-failure, 1–0) question, the probability of success is p, and the failure’s probability is q=1-p. Let’s consider an example. You are practicing free throws during basketball training. From the season statistics, we know that the probability that you will score a point is 75%. Your coach told you that if you score 17 points out of 20 attempts, you will start for the next match. What is the probability that you score exactly 17 points? We need to assume that the probability of a successful free throw shot is independent of the previous result (the mental strength does not play a role here). We also do not care about the order of scoring, such that it does not matter whether you fail first, third or last shot. Thus, this is a binomial distribution. We can use the binomial density function as given above and get: We can repeat this excercise for other scores. As a result, we get the binomial distribution plot (PDF): But you want to score at least 17 points, not exactly 17 points. So what is the probability that you will be...
Muhammad Yahya Patel (Mo) is a highly acclaimed Security Engineer and member of the Check Point Office of the CTO. Mo has over 10 years of experience in cyber security, ISP field & operations and ICT. Before joining Check Point, he worked as a Security Consultant designing and implementing security solutions for private and public sector organisations including the UK’s National Health Service. He is a trusted advisor amongst some of the UK’s top VARs and works closely with C-levels on strategy and security challenges. In this outstanding interview, expert Muhammad Yahya Patel shares perspectives about closing the cyber security talent gap, retaining talent, and training the next generation of cyber security professionals. The topic of cyber security skills is becoming widely discussed among the industry and within many organizations; including government groups. Can you share insights around this? The timing of this interview is perfect because the UK government department DCMS just released their 2022 report, Cyber Security Skills in the UK Labour Market. In this report, we find that the average number of vacancies per business has increased. If we take a look at cyber security businesses that contribute to a large portion of the hires in the industry, since 2020, more than half of these businesses have tried to recruit people into cyber roles. We are seeing an increasing trend where cyber vacancies prove difficult to fill. The common denominator amongst candidates is lack of knowledge and skills. It’s also difficult to fill positions when there is a high demand for candidates, as this drives competitive behavior between businesses when it comes to attracting the right...
Bristol-based businessman Brett Edgecombe, Director at 101 Data Solutions, says it’s more important than ever to cultivate a new generation of cyber security talent to protect our digital future, with Bristol being an excellent place for people to start their career in this industry. The recent DCMS Annual Cyber Sector Report, which assesses how the UK’s cyber security industry has performed, highlighted Bristol’s role. In the report, Digital Secretary Nadine Dorries said: “Cyber security firms are major contributors to the UK’s incredible tech success story. Hundreds of British firms from Edinburgh to Bristol are developing and selling cutting-edge cyber tools around the world that make it safer for people to live and work online.” Brett Edgecombe, Director at 101 Data Solutions, believes that Bristol could be the UK’s cyber capital owing to its highly skilled workforce, top research universities, and thriving software development industry: “While many careers are characterised by fluctuating demand, cyber security and jobs throughout the data protection industry are seeing strong growth. Moreover, it’s expected to have one of the fastest growth rates in the future. That makes it an excellent choice for a career and one I would encourage more people to explore. “We know Bristol has a thriving startup environment, and we are seeing an increasing focus on cybersecurity. Our city has many security-related startups with lots of cybersecurity experts and entrepreneurs in the city keen to collaborate. Bristol is leading the way in cultivating a new generation of cyber security talent, which is excellent news that Bristol can not only survive but thrive in a time of economic uncertainty. “In the coming years,...
Hear from CIOs, CTOs, and other C-level and senior execs on data and AI strategies at the Future of Work Summit this January 12, 2022. Learn more Having spent more than a decade working on smart buildings and energy efficiency for commercial property, BrainBox AI cofounder and chief technology officer, Jean-Simon Venne, sees AI-powered autonomy as the necessary next step in the battle against entropy — and against climate change. The problem with engineering buildings any other way is that efficiency tends not to last, Venne says. “I’ve worked on energy efficiency in large buildings pretty much all over the planet in places like Dubai and Las Vegas. When you’re done with the project, and the building is pretty efficient, you’re happy with the results, and you go away. That’s when things slowly start to degrade.” Improving the energy efficiency of buildings is a global concern, given that, by some estimates, commercial buildings account for about 40% of greenhouse gas emissions. But what happens over time, according to Venne, is that subsystems malfunction, or else they get turned off or misconfigured. Conditions change, and problems not accounted for in the initial design emerge. What’s needed instead is something more like the engineering that goes into a race car, where the initial design is as perfect as the engineers know how to make it upfront, but every few laps during a race, they fine-tune it further for the specific conditions on the track that day, Venne said. His inspiration for a solution that is less labor-intensive than car racing also comes from the world of automobiles — specifically self-driving cars....
Posted on Monday, May 16th 2022 For those of you following our coverage of techies transitioning into successful entrepreneurs, here is another terrific case study. Cyber Security is probably the tech industry’s more prolific segment. James discusses a specific approach to network security that has become increasingly more contemporary and relevant: segment-based policy. Sramana Mitra: Let’s start by introducing our audience to a bit of your background as well as Elisity. James Winebrenner: I’m the CEO of Elisity. I had been in the security and network infrastructure for about 25 years. I started my career at Check Point software back in the 90s. I’ve been very blessed to have a career looking at a number of different trends in security and network infrastructure. I’ve done stints at Cisco. The last startup that I did from ground zero was Viptela. I stayed on and ran that for about two years. I was anxious to get back to building something again. I had an interesting background on both the network and security side of things. Frankly, that’s where Elisity is focusing. There’s a lot that we learned through the software-defined market evolution around the need for security to be baked into a lot of the infrastructure evolution, specifically, the trends around segmentation and being able to bring segmentation much deeper into the network and make it easier to build privileged access policy around how infrastructure interacts on those network segments. The focus for Elisity is to bring identity-based micro-segmentation into physical networks and extend that into the cloud edge. In doing so, it allows organizations to move away from implicit trust...
