Security review framework
Threat model
Identify assets, adversaries, entry points, trust assumptions and out-of-scope threats.
Privilege boundaries
Document which component can access each resource and how that authority is granted or revoked.
Isolation
Define failure containment and the security consequences of compromised services.
Verification
Link tests and reports to explicit acceptance criteria; distinguish tests from independent audits.
Minimum threat-model structure
- Assets: credentials, user files, cryptographic keys, system integrity, browser sessions and update artifacts.
- Adversaries: malicious websites, untrusted extensions, compromised user-space services, malicious packages and attackers with physical access.
- Entry points: boot media, device interfaces, IPC, file parsers, network protocols, browser rendering and extension interfaces.
- Trust boundaries: kernel versus user space, service-to-service communication, browser privileged code versus web content, and verified versus untrusted packages.
- Security objectives: least privilege, isolation, integrity, confidentiality, availability and recoverability—each with explicit scope and limitations.
Security claims require measurable evidence
Threat model
Identify assets, adversaries, assumptions and out-of-scope threats before selecting controls.
Enforcement
Link each security requirement to the code path that enforces it and the failure modes it addresses.
Adversarial validation
Use negative tests, fuzzing and fault injection where appropriate; report coverage and residual risk.
Updates and response
Document vulnerability intake, security updates, signing, rollback and incident communication.
