Gartner CARTA

Gartner CARTA: Strategic approach to the continuous, risk-based adjustment of security decisions. The term is relevant to the assessment and design of modern security architectures and should be applied within the specific technical and organizational context.

How it works and where it fits

Gartner CARTA creates a traceable framework for security decisions. Scope, assumptions, evaluation criteria, responsibilities, and expected outcomes are made explicit. It is therefore more than documentation: it connects business objectives and protection needs to concrete controls, accepted residual risks, and verifiable evidence.

Practical security relevance

Effectiveness requires an accountable owner, periodic review, and measurable criteria. Decisions should use current data, while exceptions record rationale, duration, and compensating measures. Audits and metrics should test not only whether a requirement formally exists, but whether it is applied in daily work and actually reduces the intended risk.
