Security is one of the most important aspects of creating and verifying the quality of software. It’s also a factor that’s gaining more and more importance every year – the vast variety of new technologies makes it difficult to keep up with security updates. How to take care of the adequate level of security of the software we create?
Methods of software securing are not only the aspect that’s gaining importance every year, they’re also an extremely and complicated field. The pace in which current solutions lose their relevance, development of the AI and introducing solutions like IoT don’t make it easier to create software with higher level of security. That’s what makes software more vulnerable to all kinds of attacks and breaches.
Most popular methods of cyberattacks
Social engineering and malware still pose the greatest threat to software security. In the first case we’re dealing phishing. In this method the victim is deceived, for example, via email, to give the attacker some sensitive information. The second big issue is malware, which blocks data on a computer and demands payment to unblock it. Among other popular threats to cyber security are malicious programs that create vulnerabilities in the system and get sensitive information, hardware attacks and IoT attacks based on breaching data security.
How to secure your software?
The rules of creating secure software become more and more rigorous. It results from a growing number of threats and not so many ways to prevent them. However, there are some good practices which minimize the risk of the app being exposed to an attack.
First of all, security policy
Security policy should be a starting point for every project. It’s nothing else than a list of rules concerning security , and when those rules are followed, they help to discover limitations and breaches in security. Abiding by the rules of security policy from the beginning saves time on checking for errors in the next stages of the project.
While creating safe software you should pay attention to the external apps it’s based upon. Choose only verified and safe systems – libraries or frameworks from third party providers could pose an even greater threat to the software than the code itself.
The app should be a subject to constant analysis – both static and dynamic, which helps identify errors in code. It allows to detect any errors before the production stage.
Modelling different threats our software may encounter is certainly a good practice. If you understand how the final product works and can visualize any potential threats at the very beginning of its life cycle, it will be easier to eliminate those threats before they even occur.
Life cycle of software has to include security tests performed as you go and constant eliminating of any errors occurring during those tests. Tests should be performed on every stage of software development – from the very beginning to the final stages of the project, when the penetration testing is vital for finding any loopholes in the product. It’s very important – testing in the early stages won’t be enough. Some of the app’s premises may have changed at some point during the project.
Please remember that software is developing constantly. When we deliver a safe app to the client it doesn’t mean it will still be safe a few months from now. Cyberattacks is one of the fastest growing fields in IT at the moment, and according to experts the number of threats and their varieties will be continuously growing. If you want to ensure that your product is safe, remember that testing is a never ending process – it should be performed on a regular basis, on every stage of software development. Invest in educating your team about cyber security and tools needed in this area. Teach your team to identify design defects on every stage and the best coding practices. Analise business threats, rules for app safety and security mechanisms – it’s the only way to increase safety of your software and respond to more and more advanced forms of cyberattacks.
