Computer viruses usually spread throughout the system before being detected A worm is software program that replicates itself in areas of idle memory until the system fails. The most frequent victims of program viruses are microcomputers Audit trails in computerized systems are comprised of two types of audit logs: detailed logs of individual keystro and event-oriented logs. In a telecommunications environment, line errors can be detected by using an echo check. The message authentication code is calculated calculated by the sender and the receiver of a data transmission. The request-response technique should detect if a data communication transmission has been diverted. A value added network can detect and reject transactions by unauthorized trading partners.

In a hierarchical topology, network nodes communicate with each other via a central host computer. Polling is one technique used to control data collisions intermediary in a smurf attack is also a victim A ping is used to test the state of network congestion and determine whether a particular host computer is connec and available on the network.
