A defense contractor has a complex network design with multiple VLANs. The network is divided into three VLANs: VLAN 10 for the administrative offices, VLAN 20 for the engineering department, and VLAN 30 for the manufacturing floor. The company’s System Security Plan states that VLANs are used to create logical network segments and improve security. A Layer 3 switch is responsible for routing traffic between the VLANs, and the switch is configured to allow any type of traffic between the VLANs. How should VLANs be treated when defining the contractor’s CMMC Assessment Scope?
