The data is divided into small packets and send it over the network, at destination point these packets are combined together and become orignal information.
Is an example of reactive, signature based IDS/IPS
Reactive, signature based IDPS technology is one of the many methodologies used to detect attacks. In a signature based IDS, a misuse detection identifies intrusions by watching for patterns of traffic and compare them against observed events or a database of signatures from known threats. Reactive IDS/IPS, on the other hand, will not only detect and alert malicious traffic but also take pre-defined proactive actions. Using MRTG, Ntop, and SNMPC in routers will monitor traffic and help network managers easily see issues like DOS attacks and security problems.
