Which of the following security architectures defines how to integrate widely disparate applications for a world that is Web-based and uses multiple…

Service-Oriented Architecture (SOA) is an architectural style for building software applications that use services available in a network, such as the web. Its fundamental principle is to achieve loose coupling among interacting software agents. SOA is designed specifically to integrate disparate applications, often running on different platforms and built with different technologies, by exposing their functionality as standardized, discoverable services. This approach directly addresses the need to connect heterogeneous systems in a web-based world, promoting interoperability and reusability across an enterprise.

A. Sherwood Applied Business Security Architecture (SABSA) is a framework and methodology for developing risk-driven enterprise security architecture, not a specific application integration pattern.

B. Service-oriented modeling and architecture (SOMA) is a methodology developed by IBM for identifying, specifying, and realizing services for an SOA; it is the process, not the architecture itself.

C. Enterprise architecture is a holistic discipline that includes business, data, application, and technology domains. SOA is a specific style within the application architecture domain, making it the more precise answer.

"The SOA paradigm

" the paper states

"SOA is an architectural paradigm for building software applications that use services available in a network... SOA promotes loose coupling between service providers and service consumers

which makes it possible to build flexible

configurable and composite applications." (DOI: https://doi.org/10.1007/s00778-007-0044-3)

"SOA and Service-Orientation

" it defines SOA as "an architectural style that supports service-orientation" and emphasizes its role in integrating heterogeneous environments.
