Definitions
Key terms and concepts that form the vocabulary of security architecture. Clear definitions enable consistent communication across teams and organizations.
IT Architecture
Why do we need IT Architecture? Abstract system descriptions are essential to achieve qualities like sustainability, dependability, scalability, and performance - these don't emerge naturally from simply combining functional components.
IT Risk
Most IT risk discussions focus narrowly on IT Security, yet modern business processes depend heavily on IT and risk management is a critical corporate governance concern that extends much further.
IT Security
Security provided by IT systems can be defined as the system's ability to protect confidentiality and integrity of processed data, provide availability of the system and data. Together these are referred to as the CIA characteristics (qualities).
IT Security Architecture
Combining our definitions of IT Security and IT Architecture gives us a comprehensive definition of IT Security Architecture.
IT Security Patterns
Design patterns have significantly influenced security pattern development. Our OSA approach combines structured control catalogues with visual design patterns.
IT Security Requirements
IT Security Requirements describe functional and non-functional requirements that need to be satisfied in order to achieve the security attributes of an IT system.
