STRIDE model
STRIDE is a model of threats developed by Microsoft[1] for identifying computer security threats.[2] It provides a mnemonic for security threats in six categories.[3]
The threats are:
- Spoofing of user identity
- Tampering
- Repudiation
- Information disclosure (privacy breach or data leak)
- Denial of service (D.o.S)
- Elevation of privilege
The STRIDE was initially created as part of the process of threat modelling. 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.[4]
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 threats 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 |
