STRIDE is a model of aggregated threats developed by Praerit Garg and Loren Kohnfelder at Microsoft[1] for identifying computer security threats.[2] It provides a mnemonic for security threats in six categories.[3]
The threats are:
- Spoofing
- Tampering
- Repudiation
- Information disclosure (privacy breach or data leak)
- Denial of service
- Elevation of privilege[4]
The STRIDE was initially created as part of the process of threat modeling. STRIDE is a model of threats, used to help reason and find threats to a system. It is used in conjunction with a model of the target system that can be constructed in parallel. This includes a full breakdown of processes, data stores, data flows and trust boundaries.[5]
Today it is often used by security experts to help answer the question "what can go wrong in this system we're working on?"
Each threat is a violation of a desirable property for a system:
| Threat | Desired property |
|---|---|
| Spoofing | Authenticity |
| Tampering | Integrity |
| Repudiation | Non-repudiability |
| Information disclosure | Confidentiality |
| Denial of Service | Availability |
| Elevation of Privilege | Authorization |
Notes on the threats
Repudiation is unusual because it's a threat when viewed from a security perspective, and a desirable property of some privacy systems, for example, Goldberg's "Off the Record" messaging system. This is a useful demonstration of the tension that security design analysis must sometimes grapple with.
Elevation of Privilege is often called escalation of privilege, or privilege escalation. They are synonymous.
