Definition - What does Security Architecture mean?
Security architecture is a unified security design that addresses the necessities and potential risks involved in a certain scenario or environment. It also specifies when and where to apply security controls. The design process is generally reproducible.
In security architecture, the design principles are reported clearly, and in-depth security control specifications are generally documented in independent documents. System architecture can be considered a design that includes a structure and addresses the connection between the components of that structure.
A system architecture or systems architecture is the conceptual model that defines the structure, behavior, and more views of a system.[1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
A system architecture can consist of system components and the sub-systems developed, that will work together to implement the overall system. There have been efforts to formalize languages to describe system architecture, collectively these are called architecture description languages .
