Introduction
What security testing is and what it is used for
Nowadays, we live in a time of constant innovation, in the software world, when technology plays a significant role in people’s life, therefore, it is crucial to protect private data. The best examples of security software are firewalls, antiviruses, encryption software.
Characteristics of Software Security Testing
Security testing is one of the non-functional tests, and it has owned characteristics. In particular, it focuses on “negative” testing scenario, i.e. special attention is paid to the issues when the software app shows an error. In some cases, the errors allow revealing flaws that may cause a significant loss.
Security testing companies are successful in protecting mobile & web applications. Their services help to remove IT security threats and maintain compliance.
Also, one should think about the system’s crash from a cracker’s perspective, i.e. to use similar tools, test the software and even code.
However, it is a challenge to evaluate the quality of such testing process. Given that 99 vulnerabilities are found but only one is missed, this one error may involve negative consequences.
Non-functional requirements are also of great importance, for instance, usability testing. Unfortunately, usability and security are not easy to harmonize since the two cannot coexist and security is most often prioritized.
As a rule, security testing is performed according to the matrix for security risk assessment or just list of necessary security requirements. It allows significantly reducing the number of vulnerabilities in security mechanisms.
There must be access to the code to scan it for potential vulnerabilities.
A security testing company usually employs specialists who have substantial knowledge of programming languages and operating systems, in other words, highly qualified professionals.
Challenges in Security Testing of Software Products
Cross platform applications. Different drivers, configurations, hardware. All this makes the application work in a different way on various operating systems. Consequently, different aspects are taken into consideration.
Testing Methodologies
- One of the main techniques is code review performed by a qualified development team.
- Exploratory testing is also applicable to security testing.
Services of a pen testing company are necessary as well. Otherwise, it is not a security testing. Pen tests can be run remotely, by emulating attack over the Internet, by a person who has physical access to your networking gadgets.
