Abstract
An authentication system includes an authentication module maintaining a store of credentials for a set of users. In response to an identity specified by credentials provided from a requestor address not being found in the store of credentials, the authentication module transmits an authentication failure response. In response to the provided credentials matching selected credentials, the authentication module transmits an authentication success response. The authentication system includes an analyzer module configured to determine a number of identity-not-found failures corresponding to a first address, identify a triggering event in response to the number exceeding a predetermined threshold, and, in response to the triggering event, add the first address to a block list. The authentication system includes a query module configured to, in response to a query for a specified address, determine whether the specified address is present in the block list and, if so, instruct transmission of the authentication failure response.
