Windows end-users and Internet routing technology have both become more frequent targets of intruder activity. The control mechanisms for DDoS attack networks are changing to make greater use of Internet Relay Chat (IRC) technology. The impacts of DoS attacks are causing greater collateral damage‚ and widespread automated propagation itself has become a vehicle for causing denial of service. While DoS

Instructor-led training allows the instructor to gauge if the material is being understood at all stages of the training class. All participants are following along at the pace set by the instructor allowing the class to remain on topic and flow from one area to the next as a cohesive unit. On-line learning allows agents
