| Description | ||||
| Multiple network connections can provide additional attack vectors to a system and must be limited. The "Minimize the number of simultaneous connections to the Internet or a Windows Domain" setting prevents systems from automatically establishing multiple connections. When both wired and wireless connections are available, for example, the less preferred connection (typically wireless) will be disconnected. | ||||

Details
Check Text (C-253364r958358_chk)
The default behavior for "Minimize the number of simultaneous connections to the Internet or a Windows Domain" is "Enabled".
If it exists and is configured with a value of "0", this is a finding.
Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \SOFTWARE\Policies\Microsoft\Windows\WcmSvc\GroupPolicy\
Value Name: fMinimizeConnections
Value Type: REG_DWORD
Value: 3 (or if the Value Name does not exist)
Fix Text (F-56767r890454_fix)
The default behavior for "Minimize the number of simultaneous connections to the Internet or a Windows Domain" is "Enabled".
If this needs to be corrected, configure the policy value for Computer Configuration >> Administrative Templates >> Network >> Windows Connection Manager >> "Minimize the number of simultaneous connections to the Internet or a Windows Domain" to "Enabled". Under "Options", set "Minimize Policy Options" to "3 = Prevent Wi-Fi When on Ethernet".
