Guide: Security Testing and Validation

Importance:
Security testing and validation is essential in the software development life cycle (SDLC). It helps to identify and address potential vulnerabilities and ensure that the software operates securely. Without this step, software is more prone to security breaches, impacting not only the functionality of the software, but also potentially causing harmful consequences to the end-users.

What it is:
Security testing and validation is a process where a software system is tested and validated in terms of security. The goal is to ensure that the system fulfills the necessary security requirements and to identify any security defects in the system.

How it works:
During security testing and validation, various techniques are employed to ensure the software is secure. This can include automated vulnerability scans, manual code reviews, and penetration testing among other strategies. The goal is to identify any potential areas where security may be compromised and to validate that security requirements have been met.

Exam Tips - Answering Questions on Security Testing and Validation:
Understand the process: Be sure to understand what security testing and validation involves, the common techniques used, and why it's such a critical part of the SDLC.
Know the techniques: Be prepared to answer questions about different security validation methods, such as vulnerability scanning and penetration testing.
Consider the impact: Consider what could happen if security testing and validation was not performed. This can help you appreciate the importance of this step and be prepared to answer questions on the subject.
