Red and blue teaming are well-established concepts in information security, but recent years have given rise to a more collaborative approach – purple teaming. To defend against rapidly evolving cyber threats, businesses need to continually adapt and innovate. This means that red and blue teams must work together on an ongoing basis to maximise their individual and collective impact. Red vs blue teams – what’s the difference? A red team is a group of offensive security professionals tasked with using real-life adversarial techniques to help organisations identify and address vulnerabilities across infrastructure, systems and applications, as well as weaknesses in processes and human behaviour. In contrast, a blue team, typically based in a Cyber Security Operations Centre (CSOC), is a group of analysts and engineers responsible for defending organisations from cyber-attacks through a combination of threat prevention, deception, detection and response. Implementing a joint approach Regardless of size, industry or resources, all organisations need red and blue team expertise to effectively combat cyber threats. Red team activities, from vulnerability assessments and penetration testing to full-scale cyber-attack simulations, are specifically designed to identify security exposures by challenging blue teams and assessing detection techniques and processes. Red team assessments can be used to test organisations against the latest tools, tactics and procedures used by criminal adversaries, and provide vital feedback to improve threat hunting, monitoring and incident response. The reality for many organisations, however, is that red and blue teams are often completely separate and disconnected entities. In some small organisations, for example, in-house IT staff are often tasked with monitoring, detection and response, while ethical hackers are commissioned by external...
There are many ways to conduct a technical interview, and they depend from company to company. You might get whiteboard designing of architecture system, writing an algorithm, or some coding challenge. After working with multiple companies and going through many interviews from both sides, I prefer coding ones. More specifically, making something like a to-do application. By doing it, in an hour, I can assess if a person is junior, mid-level, senior, or architect. In this text, I cover how I do it and what knowledge I expect for which experience level. Application to build I prefer a to-do application. The model for an item of it is straightforward. All you need is a text, a unique identifier, and some flag indicating its status. All to-do applications display the list of all items, enable input of a new item, toggle the item’s status, and delete them. I don’t expect to spend more than 45 minutes up to an hour. That is not a long time, so I don’t expect candidates to do everything, just enough to show how they think and what they know. I provide candidates with initial data. It is just a JSON file with few items located in the public folder. In React, every file located in that folder is available, and this one you can request by making a get request to /todo.json. I am okay with googling for documentation, and I make it clear at the beginning of the interview. And this is also an indicator of candidate experience level. If the candidate checks documentation for some API, that is fine. But if the candidate...
Becoming a full-stack web developer requires you to hide tons of skills. For beginners, it’s often tough to seek out the proper learning path and to realize the quick results. At first sight, it’d be overwhelming to know what you would like to find out and the way everything fits together at the top. This post will offer you a summary of technologies you’ll concede to learn for being a full-stack developer in 2019 and beyond. We’ll start to require a glance at the inspiration and programming languages then move forward to more advanced topics like frameworks and extra tools. This list will provide guidance to seek out your path through the online development jungle in 2019. Together with a brief description of the relevant topics, this post contains a link to great learning resources in order that you’ll start quickly to expand your skill-set. Foundation The best thanks to beginning your web development career is to urge excellent at HTML & CSS which is that the basis for everything else. HTML & CSS The Hypertext terminology (HTML) is important for each website you’re implementing. By using HTL you’re defining and structuring the content of an internet site by employing a simple markup syntax. Cascading Style Sheets (CSS) may be a simple way for adding styling to your websites (e.g. adding fonts, colors, layout etc). Having understood HTML you ought to definitely advance to CSS and confirm to know the fundamentals. HTML and CSS are two essentials every web developer must know. This was valid in 2018 and can even be valid in 2019 … Programming Languages Learning JavaScript...
Single page apps demand the front-end developers to become better software engineers. CSS and HTML are not the biggest concern anymore, in fact, there is no longer just a single concern. The front-end developer needs to handle XHRs, application logic (models, views, controllers), performance, animations, styles, structure, SEO, and integration with external services. The result which emerges from all those combined is the User Experience (UX) which should always be prioritized. AngularJS is a very powerful framework. It is the third most starred repository on GitHub. It is not difficult to start using, but the goals that it is intended to accomplish demand comprehension. No longer can AngularJS developers ignore memory consumption, because it will not reset on navigation anymore. This is the vanguard of web development. Let’s embrace it! Common Mistake #1: Accessing The Scope Through The DOM There are a few optimization tweaks recommended for production. One of them is disabling debug info. DebugInfoEnabled is a setting which defaults to true, and allows for scope access through DOM nodes. If you want to try that through the JavaScript console, select a DOM element and access its scope with: It can be useful even when not using jQuery with its CSS, but should not be used outside of the console. The reason being that when $compileProvider.debugInfoEnabled is set to false, calling .scope() on a DOM node will return undefined. That is one of the few recommended options for production. Please note that you can still access the scope through the console, even when on production. Call angular.reloadWithDebugInfo() from the console and the app will do just that. Common...
When getting started on developing a mobile app, it’s easy to get carried away thinking about how your app will look and function, , and the overall value you imagine it bringing to your users. But one of the first things you should be thinking about is what type of app you’ll build. There are native apps, hybrid apps, web apps, and progressive web apps. Choosing the right type is crucial to bringing your dream app to life, so think carefully about the decision. In this article, we’ll bring you up to speed on the different types of , the technology behind them, and how to make the right choice. Chapter #1: Native Mobile Apps When you hear the term “native app”, this simply means that the mobile application was built for a specific operating system (OS). Most mobile devices use either iOS or Android OS. So creating an app that’s native to one of these systems means making the most of the device’s functionalities. With that said, , for example, can’t be used for other platforms, like Android devices. 1.1 How Native Apps Work First and foremost, native apps are coded using like Kotlin, Java, Swift, and C++. They function by having complete access to a device’s hardware and functionality. The platform provides developers with a set of standardized tools, libraries, code samples, and documentation, also known as a software development kit (SDK), that will help them create an app for that specific platform. Platforms also provide an integrated development environment (IDE) for developers to use to write and test their software. This is a software suite that...
