Authorization JWT

Service Name: JSON Web Token

Service Description: JSON Web Tokens (JWTs) are an open standard (RFC 7519) that define a compact and self-contained way for securely transmitting information between parties as a JSON object. JWTs are commonly used for authorization purposes in web applications and APIs.

Service Address: https://jwt.io/

Validation Type: API Auth

IP Allow list: Does not exist

Secret Access Scope: Grants access to protected resources based on the claims contained within the token.

Secret Revokement URL: Does not exist (JWTs are stateless by design and typically require backend revocation mechanisms)

Secret Example: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

Suspicious Activity Investigation Instructions:

  • Check server logs for unusual JWT usage patterns or high volume of requests
  • Verify JWT signature validation is properly implemented
  • Look for tokens with extended expiration times
  • Check for tokens being used from unexpected IP addresses or locations
  • Review user activity logs for actions performed using the JWT

Mitigation Instructions:

  • Implement token blacklisting on the server side
  • Update the signing key used for JWT validation
  • Reduce token expiration time to minimize exposure
  • Implement proper token rotation policies
  • Add additional claims validation (IP binding, device fingerprinting)
  • Consider implementing refresh token mechanisms with revocation capabilities
