You will set up and configure a firewall in this project to control how data moves between internal and external networks. You will use tools like pfSense, Cisco Packet Tracer, or Linux iptables to set up rules that block unsafe traffic (like Telnet and FTP), limit access to sensitive services, and only let secure protocols like SSH and HTTPS through. Then, you will test the firewall by sending different types of traffic through it and checking the logs to see if packets are allowed or not. This project helps people understand how firewalls protect networks from unauthorized access and enforce security policies.

This project is about making a safe office or home network by using basic security rules. You will make a network diagram that shows routers, switches, firewalls, and wireless access points. You will also divide the network into VLANs for different departments, such as HR, IT, and Guests. You will set up security features like access control lists (ACLs), intrusion prevention systems (IPS), WPA3 encryption for Wi-Fi, and a DMZ for hosting public services. The final design will have a written explanation of how each part and setup helps keep the network safe from cyber threats.

This project will teach you how to find and fix problems in a network. You will use scanning tools like Nmap, OpenVAS, or Nessus to look for open ports, services that aren't set up correctly, and software that is out of date in a test environment. After finding weaknesses, you will use hardening methods like turning off unused ports, installing software updates, enforcing strong password policies, and setting up secure authentication. Finally, you will scan the network again to make sure that the problems have been fixed. This project gives you real-world experience in finding and fixing security holes.
