Why do you need enterprise architecture?
Information systems are made up of several interconnected components, with the aim of providing services. To ensure that the interaction between these elements is reliable and optimised, organisations need to develop and implement an overall architecture to support their information systems, taking security aspects into account.
The Information Security Architecture (ISA) is a high-level document that describes a structured inter-relationship between business, process and technology components. The ISA makes it possible to avoid developing security solutions in silos, which could lead to compatibility problems. In other words, the ASI helps to reduce vulnerabilities by describing how the various security components should communicate in complete security.
