A Survey On Network Packet Inspection And ARP Poisoning Using Wireshark And Ettercap

A network consists of a collection of nodes such as hubs, bridges, switches, routers, firewalls, brouters, packet shapers. The hubs help in connecting two devices. The bridges and switches function in layer 2 of ISO-OSI (Open Systems Interconnection). Routers perform the role of delivering packets from source to destination. Firewalls protect the networks by filtering the traffic between sender and receiver. The packet shapers help in regulating the traffic by cutting out spikes in a connectivity. The network is being utilized as 24*7 days support. The network is being exposed to various kinds of attacks such as ARP (Address Resolution Protocol), DDOS (Distributed Denial of Service). Hence the performance monitoring plays a vital role in preserving a network. The tools such as wireshark and ettercap are being analyzed in this paper. The network traffic is being interpreted by wireshark. Ettercap analyzes ARP poisoning attack. The preventive actions are taken based on the output of the monitoring tools.
