This project focuses on the practical implementation and testing of network security controls, as a follow up to a network security plan. The assignment requires the student to implement and document at least five security controls, detailing the objective of each control, the resources used (hardware and software), and a proof of concept using open-source software. The project involves creating a block diagram to illustrate the system, providing configuration instructions with screenshots, designing and implementing a test plan, and analyzing the test results. Specific examples include the implementation of a RADIUS server. The project concludes with a summary of the implementations and a list of references. This is a comprehensive project that allows students to gain hands-on experience with the practical aspects of network security implementation and testing.
