What are the different security testing techniques used in the SDLC?

There are several security testing techniques used in the Software Development Life Cycle (SDLC). Some of the commonly used techniques include:

1. Vulnerability scanning: This technique involves scanning the software or system for known vulnerabilities and weaknesses. It helps identify potential security risks and allows for timely remediation.

2. Penetration testing: Also known as ethical hacking, penetration testing involves simulating real-world attacks to identify vulnerabilities and weaknesses in the system. It helps assess the effectiveness of security controls and measures.

3. Security code review: This technique involves reviewing the source code of the software to identify any security flaws or vulnerabilities. It helps ensure that the code is secure and follows best practices.

4. Security requirements analysis: This technique involves analyzing the security requirements of the software early in the SDLC. It helps ensure that security is considered from the beginning and integrated into the development process.

5. Threat modeling: This technique involves identifying potential threats and risks to the software or system. It helps in designing appropriate security controls and countermeasures to mitigate these threats.

6. Security testing tools: Various automated tools are available for security testing, such as web application scanners, network vulnerability scanners, and static code analysis tools. These tools help in identifying security issues and vulnerabilities.

It is important to note that these techniques should be integrated throughout the SDLC to ensure that security is addressed at every stage of development and testing.
