This document outlines the goals and design of a network monitoring system created by a student group. The system aims to capture packet information and detect intrusions by using a network sniffer and intrusion detection system with a graphical user interface. It was designed with use cases, diagrams and a Gantt chart. The system would feature rules for restricted traffic, packet capturing, alerts for accepted/restricted packets, and searching historical packets. It may face challenges with network control and processing speed. The project uses tools like HTML, PHP, Python, Putty and MySQL.

13. System Features
 Rules List
 Text file of restricted IP addresses and/or Port Numbers
 Network Sniffer
 Capture and display packet information
 Intrusion Detection System (IDS)
 Alerts the user of accepted/restricted packet information
 Email sent to administrator if alerts exceed 50, major intrusion
 From the database
 Captured packets can be searched from a date range
○ Example: From: Jan 1, 2015 - To: Mar 17, 2015
