It is impossible to overestimate the significance of software testing. Not only the satisfaction of end-users depends on it heavily but also your ROI and welfare in general as bugs in your software can not only disappoint users but lead to significant financial losses. For this reason, it is indeed important to entrust your software to a reliable and experienced software testing company that can provide you with appropriate services.

Types of security testing

Master of information, master of the situation. This saying is as relevant as never before. Today, information is a valuable asset that must b properly secured. As a result security testing is one of the most sought-after software testing services. It is pretty obvious, as an application cannot be considered reliable if its users’ personal data is not protected appropriately. So security testing is a complex of testing activities aimed to make sure that software can withstand cyber-attacks and identify possible weak spots and vulnerabilities that can be used by hackers to get access to sensitive information.

So let’s consider the main security testing types that are executed by the best software testing companies in the UK and all over the world.

Vulnerability scanning

Vulnerability scanning is executed by means of an automated tool to identify possible vulnerabilities in software. A vulnerability scanner inspects software to reveal SQL injections, command injections, cross-site scripting, and other outer threats.

Security scanning

Security scanning is conducted to evaluate the overall security level of software networks revealing soft spots and loopholes. Such scanning can be performed automatically and manually. However, the more sophisticated software or network is, the more complex security scan should be used. It is a good practice to run security scanning on an ongoing basis.

Penetration testing

Penetration is a hacker attack simulation carried out to check software behavior and ability to withstand as well as identify possible weaknesses and loopholes. There are two approaches to penetration testing. The first one is application penetration testing uncovering technical vulnerabilities, the second one is infrastructure penetration testing inspecting different types of hardware.

Risk assessment

Risk assessment is a procedure of core security controls identification and implementation. Complete security analysis and assessment give an opportunity to make up risk profiles for an app itself, networks, servers, etc. All in all, this type of security testing concentrates on the prevention of security issues.

Security auditing

Security auditing can be defined as testing the security of the corporate information system. It allows evaluating the efficiency and relevance of the applied security strategy confirming its correspondence with the current security regulations.

Ethical hacking

This interesting oxymoron stands for a system intrusion performed by an ethical hacker with an aim to reveal its vulnerabilities before a malevolent hacker could find and use them for his own benefit. In essence, ethical hackers leverage the same tricks and tools as their malevolent rivals but with the company’s permission in order to report then all found loopholes.

Posture assessment

Posture assessment is conducted to provide an overall assessment of the corporate security posture, providing information on existing gaps and actions that need to be taken to for optimization.

Security testing is a complex process that requires special knowledge, experience, and skills. In these terms, it is indeed important to entrust your software to real QA professionals being extremely good at software security testing.
