The deliverable that would aid a software security team in preparing a detailed schedule mapping security development lifecycle phases to the type of analysis they will execute is Security test plans. These plans are crucial as they outline the testing strategies and specific security tests that will be conducted during the development lifecycle to ensure the software meets the required security standards.
* Security test plans are developed after the requirements and design phases and are used throughout the implementation, verification, and release phases. They include detailed instructions for security testing, criteria for success, and the types of security testing to be performed, such as static and dynamic analysis, penetration testing, and code review.
* These plans are living documents that should be updated as new threats are identified and as the project evolves. They ensure that all team members understand the security goals, the risks, and the measures that need to be taken to mitigate those risks.
* By having a well-defined security test plan, the team can ensure that security is not an afterthought but is integrated into every phase of the software development lifecycle, thus producing more secure software.
: The importance of security test plans in the software development lifecycle is supported by best practices and guidelines from sources such as Microsoft's Security Development Lifecycle1 and Snyk's Secure Software Development Life Cycle principles2.
