Abstract
Apparatus, system, and method having a first counter to record a number of invalid authentication requests, a first timer to set a first time period based on a value of the first counter, and an authentication module associated with the first counter and the first timer to receive an initial authentication request that includes a username and when said username is invalid, the module is to invalidate any subsequent authentication requests under the username during the first time period regardless of whether the subsequent requests includes a valid username. The system further includes a communication medium. The method includes receiving an authentication request with new information in a first session, validating the new information, and caching the validated new information in the first session.
