Abstract
A method and system for detecting and reducing botnet activity includes tracking the number of connections to a destination address over predetermined periods of time. A persistence value is assigned to the destination address based on the number of time periods during which the destination address was connected. The persistence value is compared to a threshold value and an alert is generated if the persistence value is greater than the threshold value. Known safe destinations may be entered into a whitelist.
