Final answer:
Developing software algorithms is not a purpose of System Security Engineering (SSE) trade-off analysis, which instead deals with identifying security vulnerabilities, evaluating cost-benefit trade-offs, and mitigating system design risks.
Step-by-step explanation:
The student has inquired about the purpose that is not related to System Security Engineering (SSE) trade-off analysis. Within the options provided, the one that does not fit the purpose of SSE trade-off analysis is d. Developing software algorithms.
The trade-off analysis in SSE typically involves identifying security vulnerabilities, evaluating cost-benefit trade-offs, and mitigating system design risks. It focuses on making informed decisions about security features in the context of overall system design. Developing software algorithms, while important in other contexts, is not the direct purpose of a trade-off analysis in the scope of SSE.
