What is the purpose of Defensive Programming in software development?

The purpose of Defensive Programming in software development is primarily to help create robust, reliable software that can anticipate potential issues and pitfalls. This approach emphasizes the development of code that can handle unexpected inputs, user behavior, and other conditions that may lead to software failures or security vulnerabilities. By focusing on translating business logic into code safely, developers can ensure that the application operates correctly, even under non-ideal conditions.

While incorporating security at each phase of development is an important principle, it encompasses a broader strategy that includes various methodologies and practices such as secure coding standards, threat modeling, and risk assessments. Defensive Programming specifically aims at writing code that inherently protects the application from misuse or errors, which is a subset of the larger goal of secure software development practices.

Managing databases and facilitating continuous software delivery are also crucial aspects of software development but are not directly aligned with the specifics of Defensive Programming. These tasks involve other practices and methodologies, such as database management techniques and DevOps processes, which are outside the focus of Defensive Programming itself.
