STRIDE model

STRIDE is a threat model for identifying computer security threats. STRIDE modelling anticipates threats to the target system and builds upon an overarching model of the system, which may include a full breakdown of processes, data stores, data flows, and trust boundaries.
Developed by Praerit Garg and Loren Kohnfelder at Microsoft, it provides a mnemonic for security threats in six categories. Each STRIDE category corresponds to a core principle of information security: Authenticity, Integrity, Non-repudiability, Confidentiality, Availability and Authorization.
