Abstract: The disclosed embodiments provide a system for managing a stream-processing application. During operation, the system allocates a first host for an active instance of the stream-processing application that maintains a state during processing of one or more input streams. Next, the system allocates a second host for a first backup instance that recreates the state on the active instance by consuming changes to the state replicated from the active instance without consuming the input stream(s). During a failure on the first host, the system moves the active instance to the first host by stopping the first backup instance on the second host. Finally, the system launches the active instance on the second host to resume processing of the input stream(s) by the active instance using the recreated state from the first backup instance.

Abstract: Network communication events are filtered to remove the network communication events having a predicted unrelatedness to beaconing. Each network communication event has a timestamp, a source entity, and a destination entity. The filtered network communication events are aggregated by unique source entity-destination entity pairs. For each unique source entity-destination entity pair, the network communication events are timestamp-sorted, time differentials between the timestamps of adjacent network communication events are calculated, and a beacon likelihood metric is calculated from the calculated time differentials. Which of the unique source entity-destination entity pairs are indicative of beaconing are identified based on the beacon likelihood metric calculated for each unique source entity-destination entity pair.
