Maps to CM-7(1) via CCI-001762

Title

Use of the QUIC protocol must be disabled.

Control

Universal method: 1. In the omnibox (address bar), type chrome://policy. 2. If QuicAllowed is not displayed under the Policy Name column or it is not set to False under the Policy Value column, this is a finding. Windows method: 1. Start regedit. 2. Navigate to HKLM\Software\Policies\Google\Chrome\. 3. If the QuicAllowed value name does not exist or its value data is not set to 0, this is a finding.

Discussion

QUIC is used by more than half of all connections from the Chrome web browser to Google's servers, and this activity is undesirable in the DoD. Setting the policy to Enabled or leaving it unset allows the use of QUIC protocol in Google Chrome. Setting the policy to Disabled disallows the use of QUIC protocol.
