Training
JWT Vulnerabilities
Training Overview
The "JWT Vulnerabilities" training comprehensively covers the security vulnerabilities that can arise during the use of JSON Web Tokens (JWT). The training explains the fundamental structure of JWT, common attack vectors, and defense strategies against these vulnerabilities. JWT signature validation attacks and methods to capture the signing key will be detailed. The training addresses algorithm confusion attacks and JWT header parameter injections, demonstrating how these attacks are carried out, detected, and prevented. Additionally, practical information on safeguarding against JWT vulnerabilities will be provided.
