Performance Analysis of Snort using Network Function Virtualization

摘要

Snort is an intrusion detection system which operates together with a firewall and is an important part of the network security systems. Snort performance decreases as the traffic on the network increases. To handle packet loss, some load balancing techniques are used. In this paper, we implement Snort a network function virtualization (NFV). The objective is to reduce the packet loss in case of higher traffic flows. In our research we have implemented snort as Virtual Network Function (VNF). The proposed research is implemented, and different experiments are carried out. The results show that packet loss can be controlled by implementing Snort as VNF.
