You are an IT consultant. You are visiting a new client's site to become familiar with their network. As you walk around their facility, you note the following: When you enter the facility, a receptionist greets you and directs you down the hallway to the office manager's cubicle. The receptionist uses a notebook system that is secured to her desk with a cable lock. The office manager informs you that the organization's servers are kept in a locked closet.

A rotation of external USB hard disks are used as the backup media. You notice that the organization's network switch is kept in an empty cubicle adjacent to the office manager's workspace. You notice that a router/firewall/content filter all-in-one device has been implemented in the server closet to protect the internal network from external attacks.
