IPv6 must be disabled until a deliberate transition strategy has been implemented. Use of IPv6 transition technologies must be disabled.


Overview

Finding ID Version Rule ID IA Controls Severity
V-14262 5.050 SV-14873r3_rule Medium
Description
Any nodes’ interface with IPv6 enabled by default presents a potential risk of traffic being transmitted or received without proper risk mitigation strategy and is therefore, a serious security concern.

Prior to transition, IPv6 must be disabled on all interfaces. If the following registry value does not exist or is not configured as specified, this is a finding:

Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\

Value Name: DisabledComponents

Type: REG_DWORD
Value: 0xff or 0xffffffff

If IPv6 transition has been implemented, the following will disable tunnel interfaces allowing native IPv6.

Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\

Value Name: DisabledComponents

Type: REG_DWORD
Value: 0x1

Microsoft updated article 929852 with regard to disabling all IPv6 components, changing the value to 0xff. A value of 0xffffffff results in a 5-second delay in system startup. However, either value can be used to disable all IPv6 components.

Documentable: If disabling IPv6 on all interfaces prior to the transition to supporting IPv6 causes issues with necessary applications or services, document this with the IAO.
