Analysis Of Computer Network Security Against Packet Interception

Society has enjoyed technological developments, especially in the field of information, one of which has developed currently is the internet. In its use, the networks used by the public are LAN cables or Wi-Fi (without cables), attacks from irresponsible parties, namely hackers who can exploit important user data, intercept data such as passwords and change user data. This research discusses the evaluation of the security level of Wi-Fi facilities at University of Basrah compus,basrah, Governorate, Iraq using the Aircrack-ng, Kismet and ettercap applications. Aircrack-ng is a Wi-Fi hacking tool that is used to detect and identify open wireless signals. Kismet is alternative software whose function is exactly the same as Aircrack-ng. Ettercap is a packet sniffer tool used to analyse network protocols and audit network security, which also has the ability to block traffic on LAN networks, steal passwords, and carry out active eavesdropping on common protocols.
