Which design pattern helps eliminate accidental vulnerabilities in code?

The Secure Design Pattern is specifically aimed at integrating security considerations into the software design process, which helps eliminate potential vulnerabilities early in development. By applying this pattern, developers can ensure that security is a fundamental aspect of their architecture rather than an afterthought, leading to more robust code.

Secure design patterns encompass best practices and guidelines that address common security issues, such as input validation, authentication, and access control. This proactive approach assists in identifying and mitigating risks during the development phase, thereby minimizing the likelihood of introducing accidental vulnerabilities into the codebase.

In contrast, while a Storage Design Pattern, Code Review, and Application Vetting are all important practices within software development and security, they do not inherently focus on the design aspects that can lead to vulnerabilities. Code Review, for example, is more about examining the finished code rather than shaping its security during the design stage. Therefore, the Secure Design Pattern stands out as the correct answer because of its emphasis on addressing security from the beginning of the software design process.
