Service-Oriented Modeling Framework (SOMF)

 

The Service-Oriented Modeling Framework (SOMF) is a methodology used in cybersecurity architecture to design and develop software applications and systems that are service-oriented. SOMF provides a structured approach to modeling and designing service-oriented applications, with a focus on security.

SOMF is based on four key modeling perspectives: the business perspective, the information perspective, the application perspective, and the technology perspective. Each perspective is used to capture the relevant information for a particular aspect of the service-oriented architecture.

The business perspective is concerned with the business processes that the service-oriented application is designed to support. This perspective focuses on the business requirements and how they can be translated into services.

The information perspective is concerned with the data and information that the service-oriented application will manage. This perspective focuses on the data models and the information flows between services.

The application perspective is concerned with the services themselves and how they are designed, developed, and deployed. This perspective focuses on the service interfaces, the service implementation, and the service lifecycle.

The technology perspective is concerned with the underlying technology infrastructure that the service-oriented application will run on. This perspective focuses on the technology components, such as the middleware and the messaging infrastructure, that are required to support the services.

Overall, SOMF provides a structured approach to designing service-oriented applications that are secure, reliable, and scalable. By following SOMF, cybersecurity architects can ensure that the services they develop meet the needs of the business, are well-designed and implemented, and are deployed on a secure and reliable technology infrastructure.

The Business Perspective is one of the four key modeling perspectives in the Service-Oriented Modeling Framework (SOMF) used in cybersecurity architecture. Business Perspective is concerned with the business processes that the service-oriented application is designed to support, and it focuses on the business requirements and how they can be translated into services.

The Business Perspective includes the following details:

1. Business Process Modeling: This involves modeling the business processes that the service-oriented application will support. This includes identifying the key activities, inputs, outputs, and actors involved in each business process.
2. Service Identification: This involves identifying the services that will be required to support the business processes. This includes defining the service boundaries, service interfaces, and service contracts.
3. Service Composition: This involves defining how the individual services will be combined to support the overall business processes. This includes identifying the service dependencies and designing the service orchestration.
4. Service Level Agreements (SLAs): This involves defining the service level agreements that will be required to ensure that the services meet the business requirements. This includes specifying the performance, availability, and reliability requirements for each service.
