Why Security Testing?
With the cyber world becoming more-and-more vulnerable to attacks, security is something that cannot be compromised with. In order to develop secure applications, one really needs to use a security development lifecycle. Security must be considered and tested throughout the project lifecycle of any application.
What are the processes involved in Security Testing?
The security testing process involves evaluating the quantum of risks within the application under test and to point out the security vulnerabilities using various techniques and tools. By this it is possible to ensure that there is no data theft, there is no unauthorized access or there is no security compromise that has been made through assistance. Security testing involves Vulnerability scanning, Security scanning, Penetration testing, Security Auditing and Security Review.
Vulnerability scanning is usually performed using automated software tool which scans for the basic known vulnerability. It is an automated process performed using the vulnerability scanning tool like SARA. Next in line is Security scanning, where an assessment is done manually along with the software scanning. Although tools help in building a robust application, every tool has its own bottlenecks. That is the reason, in addition to automated scanning one is required to perform manual testing, that is going through system responses, examining the log files, error messages, error codes and the like.
The other aspect is Pen testing or Penetration testing. A real-time simulation environment is used to perform penetration testing. It is totally a Black Box, a hackers approach, the way in which Hackers use it but is done in a controlled environment. It is performed internally within the organization without breaching any security terms. Security Auditing is for specific control or compliance issue. Usually the compliance team or the risk evaluating team performs this security assessment. So, very frequent audits make the application more error prone and less vulnerable.
Finally, Security Review, which is static testing, wherein security review is perform as per the industry standards by reviewing documents, architecture diagrams and performing gap analysis. It is basically done for code reviews considering the architecture diagrams and documents which are very important. All these processes in security testing ensures that the applications developed are prone to any kind of security risks.
