Even since before the pandemic, cybersecurity was a major issue for both businesses and individuals, however the current world situation has made it even more of an important issue with so many people having to connect digitally instead of face to face. You can be sure cyber scammers have not let this change go unnoticed and the number of cyber threats has rocketed in the past 18 months. Now more than ever before it’s important for companies and the general public to be aware of the various types of threats to the security of their digital devices, and here we’ll take a look at the five most common ones to prevent you from falling into the trap. RansomwareThe clue is in the name, holding data to ransom for a price. Ransomware is a program that encrypts data on your system and effectively locks it up unless a key is used to unlock it and regain access. This type of attack is becoming more commonplace and is usually targeted at companies and larger organisations such as universities and hospitals due to the sensitive and vital information they may hold on customers, and their ability to pay the large sums requested to unlock the data. However, millions of individuals are targeted each year too on their personal computers, with important files, videos and photos locked away and unable to be restored. PhishingAimed at both small businesses and individuals, phishing is a technique that tricks users into performing a certain action which gives power to the attacker, such as filling in details on a fake website or disclosing sensitive banking or security information. This can come in the form of an email where the phisher takes the form of a trusted person and ushers them to click a link or to download a file which then executes software to steal sensitive data. Most of the time these attacks are easy to spot for the trained eye, but many times the scam works when the recipient’s guard is let down, and it only takes a second for the wrong action to be taken. MalwareA wide-ranging type of attack that can be anything from computer code which acts in a malicious way on your system to viruses and hacks that can happen when you download items from the internet or open infected emails. Malware has the purpose of damaging entire systems, and crippling networking infrastructure, and oftentimes this can be very costly to repair or replace. During this kind of attack, the system is wide open to the hacker and they are able to steal all kinds of valuable information from an organisation or individual. Most of the time, a good virus detection and malware sweeper is enough to detect, isolate and eliminate the threat, however these threats are becoming more and more sophisticated. Hacking Weak PasswordsLet’s face it, the average person who is signed up to multiple websites and uses passwords to gain access to everything from their email to their work accounts will have more passwords than they can possibly remember. Due to this, most people choose a simple password such as a name and a set of numbers which is then repeated across all of their devices with little variation. This makes a hacker’s job very easy, as once they are able to crack on password, they will have instant access to the rest of the accounts using the same one. Some websites and applications now demand stricter protocols, such as using capitals, multiple numbers and special characters, and this is then stored in password memory by our devices so we don’t have to remember them. Once a hacker has gained access to your account, they can take any number of decisions to steal your personal data and banking details to use maliciously. Denial of Service (DoS)This attack works by flooding a system with multiple requests so that it cannot process them all, and as such is unable to function properly. The ensuing attack leaves your computer very vulnerable and at this stage the attacker is able to inject malware to damage your system and steal valuable data. Another term for this is distributed denial of service where the attack is started from a network, but there are also botnets and so-called zombie systems which do the same thing, but from a wide range of locations which makes tracing the attack virtually impossible.

A Look At The 5 Most Common Cybersecurity Threats

Just starting out as an embedded software engineer? Or maybe you’re just looking to refresh your skills? Working as an embedded software engineer can be tricky – you need a wide range of niche technical skills, along with an extensive understanding of key programming languages, real-time operating systems, and device drivers. Don’t worry – we’ve got you covered with this handy guide. Keep reading for our 10 embedded software engineer tips. C/C++ ProgrammingThe first tip on our helpful list is all about getting your C and C++ programming skills up to scratch. As an embedded software engineer, these common programming languages will be your bread and butter. How do you get them up to scratch? There’s no cheat sheet here, unfortunately – you just need to do some studying. PythonThe second tip on our list is another common programming language – Python. As you may already know, Python is a language for programming that is used at a high level. It’s considered a ‘general-purpose’ language, meaning almost all software engineers will need to know about it.There’s no way around learning Python if you’re in the software sector. Luckily, there are many resources available online to help you learn about it. Assembly programming languageAnother programming language, assembly just means any programming language that is low level and has high correspondence between language instructions and instructions of the machine code. Learning assembly will be a requirement for many embedded software engineer jobs on the market. Linux operating systemEmbedded software engineers may have to use the Linux operating system and its applicable programming languages – these are PHP, Ruby, Perl, Python, Go, Haskell, Rust, and Java. Linux also includes the traditional purpose-specific languages for programming that are targeted at scripting, system configuration, and text processing. Real-time Operating Systems (RTOS)If you don’t know what RTOS is, it stands for ‘real-time operation systems’, in which a software component switches between different tasks rapidly, to give the impression that more than one program is running simultaneously on one processing core.Any successful embedded software engineer will need to know how to use real-time operation systems. Internet of Things (IoT) and Internet-based TechnologiesYou’ll only need a basic understanding of this, but you’ll need to know how IoT can be used in conjunction with software.There is more and more IoT devices being developed by the minute, so this is an important skill to have in your arsenal. Microcontrollers, or MCUsFollowing on from IoT devices, microcontrollers are part of the IoT world. They are a type of integrated compact circuit that govern specific operations in embedded systems. As an embedded software engineer, this will become very important to your line of work. MicroprocessorsA good base of knowledge to have is that of microprocessors – they contain the logic, arithmetic, and control circuitry that is needed to carry out the main functions of a computers’ central processing units. Debugging skillsThe last two tips on our list, starting with debugging skills, are quite general, but still very important.Debugging is all about finding and removing errors in the program that is actually called ‘Debugging’. To use the platform, you need to identify the bug, then find the source and correct it, to make a program usable. Ability to work with existing codebasesWe’ve saved of the most important and difficult ones until last – working with existing codebases.To get to grips with existing codebases, you first need to read carefully the unit tests, then refactor the code, introduce unit tests, and finally break the code. Don’t worry, breaking the code is just a way to see how things work – you can change it back afterward. Bottom lineThese are our essential tips for embedded software engineers. We hope we’ve helped you to outline a game plan for what you need to study up on.If you have any further questions, don’t hesitate to get in touch. We love talking about the jobs we recruit for, and just about anything else as well.

10 Essential Embedded Software Engineer Tips

Application security is facing more and more threats than ever, and companies and organisations are keen to get safe measures in place. That means hiring cyber security experts who can put these measures into place that offer superior protection. The only problem is that cyber security has a major skills gap. Here at Source, we’ve also noticed a lack of cyber security talent ourselves. Today, we’re here to talk about why this is and how to fix it. Cyber Skills GapWhy is there a cyber skills shortage? There are multiple reasons. The main one is that cyber security is constantly changing. You could say this about all technology jobs, but it’s particularly true with cyber security because of the need to keep up with hackers. The speed that software is being developed and delivered is speeding up, meaning there is a divide between developers and cyber security experts – they don’t have enough time to learn the new software. Another reason is that there appears to be a lack of university courses that specialise in cyber security. If people can’t get the training they need, there’s no chance of them becoming cyber security professionals. Bridging the Cyber Skills GapSo, what can we do about bridging the cyber skills gap? Apart from creating more training courses (that are also accessible), the challenge lies mainly with organisations and companies – they must give developers the tools to be able to keep their software safe and secure. What are these tools? One type is security test tools that are automated, meaning they are there at the beginning of the development process, helping to ensure that security is an inbuilt part of the development from the start. These types of testing tools allow developers to address threats in a way that means they don’t have to be cybersecurity experts. This is about the simple fact of using tools that developers can easily understand. The tools need to be integrated into developers’ everyday work processes. Unfortunately, this doesn’t happen enough. Software developers should have a basic understanding of cyber security, but this often gets overlooked in interviews, almost like an annoying afterthought – cyber security professionals are needed to turn this into a forethought. Successful cyber security needs to be implemented at&nbsp;every stage of the development journey. Do you work in cyber security?There’s a skills gap to bridge, and we want to make the cyber world a safer place. If you’re a cyber security professional, you can imagine that we would want to hear from you. Apply for one of our jobs, send us your CV, or give us a call, and we’ll get the ball rolling right away.

This is something that we’ve always felt passionate about. Get in touch with us now, and we’ll help you take the next step in your career. We’re looking forward to hearing from you.

Bridging Skills Gap Cyber Security

Whether you’re in university and thinking ahead to your first career role or are simply looking to try something new, then programming may have been something you’ve considered. With more of our lives being conducted on the internet, and that not set to change any time soon, then it makes sense that the need for high quality, dedicated and talented programmers is not going to be going anywhere either, and is actually set to increase. You may be aware of some of the basics of programming languages, and although it can be quite overwhelming to keep up with all of them and wonder which ones to focus on, if you’re looking to become an Android developer, then Kotlin is one that’s making some headlines recently as it definitely one to pay attention to. Just as the name Java was named after an island off the coast of Indonesia, Kotlin was named after Kotlin Island in Russia, near St. Petersburg. Although this may seem like useless trivia, knowing stuff like the name of programming languages and where they come from will be things viewed favourably when applying for jobs as it shows you’ve done your research. If you’ve never heard of it, then don’t worry, in this post we’re going to give you a full introduction to Kotlin, so that you can decide if this is something you’d like to focus on in your work as a developer. Google Prefers ItThis is probably one of the most important factors to consider with Kotlin. As we all know, Google basically runs the internet’s most used search engine – and so much of how a website performs and how visible they are really comes down to how much Google approves of them.Google recently announced that Kotlin is their preferred programming language for Android, which is definitely something to consider when deciding which programming language you’d like to focus on going forward. It’s A Cross-Platform LanguageWhile both Java and Kotlin are widely recognised and robust programming languages, they do have slight differences in their capability and functionality. With Kotlin, you have something that has the features of both, object-oriented and functional programming, whereas Java only works on object-oriented programming. Additionally, Kotlin allows those using it to create an extension function, which is something Java programmers aren’t able to do. It’s Java-CompatibleAlthough the two are different programming languages, choosing Kotlin over Java won’t leave you limited to only that. In fact, you may find it more beneficial since they work well together, so you can actually be more effective by choosing to use both Kotlin and Java. It’s Easy To UseWhen it comes to getting your head around yet another programming language, you may be feeling slightly overwhelmed at the prospect as they’re not always the easiest to learn and adopt. However, one of the reasons that Kotlin is growing in popularity is because of how easy to adopt it is. Since it can be used with Java, it’s easy to use and far more flexible and versatile than other programming languages. Safety Is PriorityThe creators of Kotlin have made sure that it’s always updated to ensure the latest safety measures for those choosing to use it as their programming language. This is even more important in today’s world where people need to be extra safe with their websites to avoid hacks, especially when dealing with sensitive and personal data from their customers. So, there you have it. A simple breakdown of what Kotlin is and how you may be able to use it. Even if you’re set on using Java right now because it’s what you know, implementing Kotlin is definitely worth considering in the future.
