Analyzing Port Scanning Tools and its Performance

Abstract

Port scanning is a process of scanning ports of a host. A port is an access point where data flows in and out of a computer. An open or closed port of a host can be identified using a port scan. Port scanning helps in handling the networks, but it can also cause damage as if someone is looking for a weak spot to breach into the system by performing critical attacks like Botnet, DOS or DDOS. To find the hosts that are vulnerable, an attacker performs port scanning of IP addresses. In this paper we will discuss few free port scanning tools and analyze the results generated in a network scan.
