Abstract: Nowadays, every different organization face security problem in the form of malicious insider or other people trying to steal organization sensitive information. So, it is necessary to provide security to this sensitive data. To overcome the problem faced by lab managing staff, and to improve the management of computers in a lab, Intruder Detector System was developed. The monitor port of the switch is connected to monitoring server to monitor a LAN when multiple switches are installed, the monitoring server should be connected to them all. This connection can either be a LAN specifically configured for monitoring traffic or it can be a physical cable. Our project aims to provide a solution to the lab managing staff by altering them if anyone tries to connect an external device/s.
