Abstract
A method may include receiving a first classification of a network address associated with a login attempt as an AVA, and in response, generating a first random number, selecting a first blocking length of time from a plurality of blocking lengths of time, calculating a first deny list duration based on summing the first random number and the first blocking length of time, and adding the network address to a deny list for the first deny list duration, and adding the network address to a parole list for a parole duration, receiving a second classification of the address as an AVA during the duration; and in response selecting a second blocking length of time from a plurality of blocking lengths, calculating a second deny list duration based on summing the second random number and the second blocking length and adding the address to the deny list for the second duration.
