Abstract: Requests to send data from a first host within a network of hosts are monitored against a record of destination hosts who have been sent data in accordance with a predetermined policy. Destination host identities not the record are stored in a buffer. The buffer size is monitored to establish whether requests from the first host are pursuant to viral activity therein.
