Malicious Traffic For Network Security Essay - 2041 Words

MALICIOUS TRAFFIC FOR NETWORK SECURITY 3.1 Intoduction Malware depends on its communication network to receive commands, extract information and infect systems. Due to this reliance on networked resources, traffic analysis becomes a valuable and effective method for detecting malware on host machines.Despite the frequency of malware traffic, net- work administrators and incident responders may not be aware of what characteristics are common to malware.By looking at traffic generated while malicious samples are executed the characteristics of the traffic can be recorded and investigated. Disclosing malicious traffic for network security 3.2 Intoduction To Network Anomaly Detection Network anomaly detection is a broad area of research. The use of entropy and distributions of traffic features has received a lot of attention in the research community. While previous work has demonstrated the benefits of using the entropy of different traffic distributions in isolation to detect generalized anomalies,there has been little effort in unconditionally understanding the detection power provided by entropy-based analysis of multiple traffic distribution used in affiliation with each other.We have demonstrated the entropy based approach to disclose malicious traffic for network security. To calculate entropy features like source and destination IP address, port numbers, packet size, connection time and the total number of packets flowing are considered.

How do protective isolations help to pr otect a network? Why do we need to separate and isolate the types of traffic? Ingress filtering is the filtering of any IP packets with untrusted source addresses before they have a chance to enter and affect your system or network. It can
