STRIDE model

STRIDE (Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, Elevation of privilege) 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 often via analysis of data-flow diagrams, which may include a breakdown into 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.
