However, architectural choices must also consider security implications. For example, a monolithic architecture may expose the entire application to vulnerabilities if a single component is compromised, while a microservices architecture can isolate the impact of a security breach.
Therefore, the architectural design phase is critical for integrating security considerations into both software and systems from the outset. This involves identifying potential threats, defining security requirements, and selecting appropriate security controls. A robust architecture considers both functional and non-functional requirements, including security, performance, scalability, and maintainability. Neglecting architectural considerations can lead to significant security vulnerabilities, increased development costs, and reduced system performance. A holistic approach to architecture, integrating both security and software engineering principles, ensures the creation of resilient and secure systems that meet organizational needs effectively.
