Script
Script Type
Remediation script
The registry key "FullSecureChannelProtection" is under the Netlogon service in the registry which is responsible for maintaining secure connections between domain controllers and clients. The key is used to control the level of protection for secure channels established by the Netlogon service. Therefore, It plays a role in preventing CVE-2020-1472. The following script will check the Windows registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters" for a value named "FullSecureChannelProtection", If the key exists and its value is 1 the script will display a message indicating that it's already set to 1. If the value does not exist or is not equal to 1 it will add the key and set its value to 1. The script then jumps to the end label and terminates.
