This is NA for systems that do not have wireless network adapters. Disabling of wired network adapters can be accomplished through various means. Third-party software that manages this is the most reliable solution. Some network adapters may have a configuration option to address this locally. 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.
