O-ESA, by the Security Forum of the Open Group, describes a framework for policy-driven security architecture. The context of security here is maintaining the confidentiality, availability and integrity of the electronic form of information. Enterprise security architecture is defined as the component of the overall enterprise architecture to fulfil these objectives.
Open Security Architecture
The book views enterprise security architecture in the larger context as part of an overall enterprise security program with relations to Corporate IT Governance, Risk Management, Physical Security and Enterprise Architecture. A good layout of enterprise security program is given in the introduction section as four concentric rings of responsibility; program management, governance, technology architecture and operations.
DescriptionDetails
This Open Enterprise Security Architecture (O-ESA) Guide provides a valuable reference resource for practicing security architects and designers. It gives a comprehensive overview of the key security issues, principles, components, and concepts underlying architectural decisions that are involved when designing effective enterprise security architectures. It does not define a specific enterprise security architecture, and neither is it a 'how to' guide to design one, although in places it does indicate some of the 'how'. This Guide updates the NAC 2004 ESA Guide to bring it up-to-date in those areas which have evolved since its 2004 publication date. In particular, it replaces the quoted extract licensed from the British Standards Institute Code of Practice for Information Security Management, by referencing rather than licensing reproduction of quoted extracts from the latest ISO/IEC 27001/2 standard.
