Ensure 'Enable firewall traversal from remote access host' is set to 'Disabled'

Опис

Chrome enables the usage of STUN servers which allows remote clients to discover and connect to a machine even if they are separated by a firewall. By disabling this feature, in conjunction with filtering outgoing UDP connections, the machine will only allow connections from machines within the local network. The recommended state for this setting is: Disabled (0) Rationale: If this setting is enabled, remote clients can discover and connect to these machines even if they are separated by a firewall. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Google\Chrome:RemoteAccessHostFirewallTraversal (REG_DWORD); compliant when it is 0. Remediation writes 0 locally; in a domain set it through the ADMX so Group Policy does not revert it.
