The main goal of security architecture and engineering is to design and implement secure systems and infrastructures. This involves a comprehensive approach to creating a secure environment for information systems, addressing the potential security threats that could compromise the systems’ confidentiality, integrity, and availability. By considering factors such as system design, configuration, access controls, and compliance with security standards, professionals in this field ensure that security is integrated into the entire lifecycle of a system rather than as an afterthought.
This goal recognizes that while it's impossible to eliminate all security threats completely, a strategic approach to security architecture can minimize risks and establish robust defenses against potential vulnerabilities. Designing secure infrastructures involves aligning security measures with business objectives, ensuring that the systems can operate securely and efficiently while still enabling the organization to achieve its goals.
