Whenever you think of the word "quantum," it might trigger the idea of an atom or molecule. Quantum computers are made up of a similar idea. In a classical computer, processing occurs at the bit-level. In the case of Quantum Computers, there is a particular behavior that governs the system; namely, quantum physics. Within quantum physics, we have a variety of tools that are used to describe the interaction between different atoms. In the case of Quantum Computers, these atoms are called "qubits" (we will discuss that in detail later). A qubit acts as both a particle and a wave. A wave distribution stores a lot of data, as compared to a particle (or bit). Loss functions are used to keep a check on how accurate a machine learning solution is. While training a machine learning model and getting its predictions, we often observe that all the predictions are not correct. The loss function is represented by some mathematical expression, the result of which shows by how much the algorithm has missed the target. A Quantum Computer also aims to reduce the loss function. It has a property called Quantum Tunneling which searches through the entire loss function space and finds the value where the loss is lowest, and hence, where the algorithm will perform the best and at a very fast rate.
Iterating from local development to Docker Compose to Kubernetes has allowed us to efficiently move our development environment forward to match our needs over time. Each incremental step forward has delivered significant improvements in development cycle time and reductions in developer frustration. As you refine your development process around microservices, think about ways you can build on the great tools and techniques you have already created. Give yourself some time to experiment with a couple of approaches. Don’t worry if you can’t find one general-purpose one-size-fits-all system that is perfect for your shop. Maybe you can leverage your existing sets of manifest files or Helm charts. Perhaps you can make use of your continuous deployment infrastructure such as Spinnaker or ArgoCD to help produce developer environments. If you have time and resources, you could use Kubernetes libraries for your favorite programming language to build a developer CLI to manage their own environments. Building your development environment for sprawling microservices will be an ongoing effort. However you approach it, you will find that the time you invest in continuously improving your processes pays off in developer focus and productivity.
One is the internal and system APIs. Core banking systems are monolith architectures. They are still based on mainframes and COBOL [programming language]. They are legacy technologies and not necessarily coming out of the box with open APIs. Having internal and system APIs helps to speed up the development of new microservices-based on these legacy systems or services that use legacies as back-ends. The second category of APIs is public APIs. These are APIs that connect a bank’s back-end systems and services. They are a service layer, which is necessary for external services. For example, they might be used to obtain a credit rating or address validation. You don’t want to do these validations for yourself when the validity of a customer record is checked. Take the confirmation of postal codes in the U.S. In the process of creating a customer record, you use an API from your own system to link to an external express address validation system. That system will let you know if the postal code is valid or not. You don’t need to have their own internal resources to do that. And the same applies, obviously, to credit rating, which is information that you can’t have as a bank. The third type of API, and probably the most interesting one, is the public APIs that are more on the service and front-end layers.
For a fraction of the salary of a full-time CISO, companies can hire a vCISO, which is an outsourced security practitioner with executive level experience, who, acting as a consultant, offers their time and insight to an organization on an ongoing (typically part-time) basis with the same skillset and expertise of a conventional CISO. Hiring a vCISO on a part-time (or short-term basis) allows a company the flexibility to outsource impending IT projects as needed. A vCISO will work closely with senior management to establish a well communicated information security strategy and roadmap, one that meets the requirements of the organization and its customers, but also state and federal requirements. Most importantly, a vCISO can provide companies unbiased strategic and operational leadership on security policies, guidelines, controls, and standards, as well as regulatory compliance, risk management, vendor risk management, and more. Since vCISOs are already experts, it saves the organization time and money by decreasing ramp-up time. Businesses are able to eliminate the cost of benefits and full-time employee onboarding requirements.
As it stands today, when a customer chooses a traditional motor insurance policy and is provided with a quote, the price they are given will be based on broad generalisations made about their personal background as an approximate proxy for risk. This might include their age, their gender, their nationality, and there have even been examples of people being charged hundreds of pounds more for policies because of their name. If this kind of profiling took place in other financial sectors, there would be outcry, so why is insurance still operating with such an outdated model? Well, up until now, there has been little innovation in the insurance sector and as a result, little alternative in the way that policies can be costed. But now, thanks to modern telematics, the industry finally has the ability to provide customers with an accurate and fair policy, based on their true risk on the road: how they really drive. Telematics works by monitoring and gathering vehicle location and activity data via GPS and today we can track speed, the number of hours spent in the vehicle, the times of the day that customers are driving, and even the routes they take. We also have the technology available to consume and process swathes of this data in real time.
One of the tactics that really stands out, and they’re not the only attackers to do it, but they are one of the first to do it, is actually making a copy and stealing the victim’s data prior to the ransomware payload execution. The benefit that the attacker gets from this is they can now leverage this for additional income. What they do is they threaten the victim to post sensitive information or customer data publicly. And this is just another element of a way to further extort the victim and to increase the amount of money that they can ask for. And now you have these victims that have to worry about not only having all their data taken from them, but actual public exposure. It’s becoming a really big problem, but those sorts of tactics – as well as using social media to taunt the victim and hosting their own infrastructure to store and post data – all of those things are elements that prior to seeing it used with Ransomware-as-a Service, were not widely seen in traditional enterprise ransomware attacks. ... You can’t trust that paying them is going to keep you protected. Organizations are in a bad spot when this happens, and they’ll have to make those decisions on whether it’s worth paying.
Rami Puzis, head of the Ben-Gurion University Complex Networks Analysis Lab and a co-author of the study, tells ISMG that the researchers decided to examine potential cybersecurity issues involving the synthetic bioengineering supply chain for a number of reasons. "As with any new technology, the digital tools supporting synthetic biology are developed with effectiveness and ease of use as the primary considerations," he says. "Cybersecurity considerations usually come in much later when the technology is mature and is already being exploited by adversaries. We knew that there must be security gaps in the synthetic biology pipeline. They just need to be identified and closed." The attack scenario described by the study underscores the need to harden the synthetic DNA supply chain with protections against cyber biological threats, Puzis says. "To address these threats, we propose an improved screening algorithm that takes into account in vivo gene editing. We hope this paper sets the stage for robust, adversary resilient DNA sequence screening and cybersecurity-hardened synthetic gene production services when biosecurity screening will be enforced by local regulations worldwide."
The vast majority of the things that we see every day are things that you never read about or hear about. It’s the proverbial iceberg diagram. That being said, in this interesting and very unique time that we are in, there is a commonality—and Sean’s actually already mentioned it once today—there are two major attack patterns that we’re seeing over and over, and these are not new things, they’re just very opportunistically preyed upon right now because of COVID and because of the remote work environment, but that’s ransomware and kind of spear phishing or regular old phishing attacks. Because people are at a distance and expected to be working virtually today and threat actors know that, so they’re getting better and better at laying booby traps, if you will, and e-mail to get people to click on attachments and other sorts of links. ... Coincidentally, or perhaps not coincidentally, one of the characters in our comic is called Phoebe the Phisher, and we were very deliberate about creating that character. She has a harpoon, of course, which is for, you know, whale phishing. She has a spear for targeted spear phishing, and she also has a, you know, phishing rod for kind of regular, you know, spray and pray kind of phishing.
The biggest advantage of a virtual firewall, however, is its support for the obvious dissolution of the enterprise perimeter. Even if an active edge DMZ is maintained through load balanced operation, every enterprise is experiencing the zero trust-based extension of their operation to more remote, virtual operation. Introducing support for virtual firewalls, even in traditional architectures, is thus an excellent forward-looking initiative. An additional consideration is that cloud-based functionality requires policy management for hosted workloads – and virtual firewalls are well-suited to such operation. Operating in a public, private, or hybrid virtual data center, virtual firewalls can protect traffic to and from hosted applications. This can include connections from the Internet, or from tenants located within the same data center enclave. One of the most important functions of any firewall – whether physical or virtual – involves the inspection of traffic for evidence of anomalies, breaches, or other policy violations. It is here that virtual firewalls have emerged as offering particularly attractive options for enterprise security teams building out their threat protection.
First of all, the system has to be told where to find the various clauses in a set of sample contracts. This can be easily done by marking the respective portions of text and labelling them with the clauses names they contain. On this basis we can train a classifier model that – when reading through a previously unseen contract – recognises what type of contract clause can be found in a certain text section. With a ‘conventional’ (i.e. not DL-based) algorithm, a small number of examples should be sufficient to generate an accurate classification model that is able to partition the complete contract text into the various clauses it contains. Once a clause is identified within a certain contract of the training data, a human can identify and label the interesting information items contained within. Since the text portion of one single clause is relatively small, only a few examples are required to come up with an extraction model for the items in one particular type of clause. Depending on the linguistic complexity and variability of the formulations used, this model can be either generated using ML, by writing extraction rules making use of keywords, or – in exceptionally complicated situations – by applying natural language processing algorithms digging deep into the syntactic structure of each sentence.
