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

YüksekDüzey 1Otomatikchrome

Açıklama

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.
