Authentication token


Perform various authentication token checks such as removing the token or changing to an invalid value.


API tokens must be unpredictable (random enough) to prevent guessing attacks, where an attacker is able to guess or predict a valid API Token through statistical analysis techniques. For this purpose, a good PRNG (Pseudo Random Number Generator) must be used.

The authentication token may have been:

  • modified to an invalid value.
  • removed from request.
  • not match length requirements.
  • configured as a signature.

An API operation failed to property restrict access using an authentication token. This allows an attacker to bypass authentication gaining access to information or even the ability to modify data.
