In an application design, what should be a priority when planning for security?

In the context of application design, prioritizing security involves incorporating security measures from the inception of the architecture. This proactive approach ensures that security is deeply embedded within the application's core functionality rather than being an afterthought. By designing security from the beginning, developers can integrate necessary safeguards against potential vulnerabilities, define secure data handling practices, and establish authentication and authorization processes that align with the application's architecture and user needs.

Building security into the architecture allows for a more cohesive and effective strategy, as it considers the overall design, including data flows, interaction with external systems, and potential threat models. This leads to a more robust and resilient application, minimizing the risk of security breaches and ensuring compliance with applicable regulations. Thus, prioritizing security from the outset is essential for creating secure applications in today's threat landscape.
