1. PROPOSED SYSTEM
 We focus on analyzing the traffic at an egress router.
Monitoring traffic at a source network enables early detection
of attacks
 Ingress filtering protects the flow of traffic entering into an
internal network under administrative control
 Egress filtering controls the flow of traffic leaving the
administered network. Thus, internal machines are typically the
origin of this outbound traffic in view of an egress filter.
 With such filtering in place, we can focus on destination
addresses and port numbers of the outgoing traffic for analysis
purposes.
EXISTING SYSTEM
 There is no well established existing system to prevent the network
traffic. Many approaches have been studied to detect, prevent and
mitigate malicious network traffic
 Work in [43] relies on input data from multiple sources (i.e., all links
in a network), while our work focuses on a single link at a time
 Our study builds on this earlier work and extends the statistical
analysis of traffic data further in analyzing other packet header data
addresses and port numbers in real-time
