05 / Diagnostic Suite / Vulnerability
Analyzes JSON Web Tokens for algorithm confusion (alg: none), key length, and token expiration tolerances.
PROPRIETARY DIAGNOSTIC ENGINE
Bear Sentinel™ Cryptographic Token Verifier
Theoretical Threat Model & Compliance Bounds
Regulatory & Compliance Liability Impact
NIST SP 800-63BPCI-DSS v4.0 (Req 8.3)
Attack Vector & Structural Vulnerability Analysis
Weak HMAC secrets or unverified alg headers allow adversaries to forge administrative tokens and bypass authorization checks.
Non-Intrusive Diagnostic Verification Protocol
Tests token verification engines against algorithm confusion, expired timestamp tolerances, and empty signature payloads.
Taxonomy Classification
Vulnerability · Enterprise Diagnostic Module
Enterprise Remediation Directive
Use asymmetric RS256/EdDSA keys with a minimum 2048-bit length. Explicitly whitelist allowed algorithms when verifying tokens.
Standard Best-Practice Reference Blueprint
