At minimum, the organization must have a policy that users turn off wireless network adapters when connected to a wired network. If wireless network adapters are not turned off when the system is connected to a wired network, this is a finding.

Fix text

Configure systems to turn off wireless network adapters when systems are connected to wired networks. If this is not possible, develop and implement a policy that users must turn off wireless network adapters when systems are connected to wired networks.
