How does STRIDE Threat Modeling Work?
STRIDE is a threat modeling framework used in application security to identify and prioritize potential security threats in systems. It categorizes threats into six distinct types, each represented by the letters in the acronym STRIDE:
- Spoofing: Unauthorized impersonation of a user or system.
- Tampering: Unauthorized modification of data or code.
- Repudiation: Denying an action or transaction made by a user.
- Information Disclosure: Exposure of confidential information.
- Denial of Service: Disruption of service availability.
- Elevation of Privilege: Gaining unauthorized permissions.
The STRIDE model involves several steps:
- Identify Assets: Determine what assets need protection, like user data or critical application functions.
- Describe the System: Outline the architecture and components of the system to establish a clear context.
- Identify Threats: Using STRIDE, categorize potential threats linked to each asset.
- Mitigate Risks: Develop strategies to reduce or eliminate identified threats.
By systematically applying the STRIDE framework, security teams can proactively address vulnerabilities and enhance the overall security posture of applications.
