Abstract
An adaptive greylist may be used to reject authentication requests that originate from a source network address that has been taken over by a malicious actor. A percentage of successful authentications for a predetermined number of authentication requests that last originated from a source network address may be calculated. Accordingly, the source network address may be added to a greylist of suspended network addresses when the percentage of successful authentications is less than a predetermined percentage threshold. On the other hand, the source network address is kept off the greylist of suspended network addresses when the percentage of successful authentications is equal to or greater than the predetermined percentage threshold.
