Case $1$: Designing a Secure Local Area Network $($LAN$)$

Objective:

You are required to design a secure LAN for a small office environment, ensuring that different departments $($e$.$g$.,$ HR$,$ Sales, and IT$)$ are properly segmented and protected.

Tasks:

Network Diagram: Create a network diagram showing the topology, including routers, switches, and VLANs.

IP Addressing: Assign IP addresses using appropriate subnetting for each department.

VLAN Configuration: Configure VLANs on the switches to ensure that each department is isolated, with limited access to shared resources.

Security: Implement access control lists $($ACLs$)$ and firewall rules to control traffic between VLANs.

Testing: Use tools like ping and tracert to verify connectivity between devices within the same VLAN and restricted access between different VLANs.

Expected Outcome:

A well$-$documented network design with appropriate IP addressing, VLAN configurations, and security measures.
