ABSTRACT
Enterprise architecture establishes the roadmap to achieve a company's mission through optimal performance of its core business processes within an efficient information technology environment and policy built on the best industry standards. Enterprise architectures are essential for evolving information systems and developing new systems that optimize their mission value using a proven system development life cycle and documenting the process throughout its lifetime. A major application has a specific function within the enterprise and usually has no other reason for existence than what it does in the department it is supporting. Policies and procedures play an important role in the effective implementation of enterprise-wide information security programs within the organization and the success of the resulting security measures employed to protect the information and information systems. Monitoring activities that take place to ensure the security controls are continually maintained and operational.
