Using Group policy to deploy the Hardening policies to all client

Hi all,

We have CIS benchmark windows OS hardening documents. Now we are manually doing all the Hardening policies to all client machines one by one, by this way its getting too delay to achieve our goal. Manual hardening take around 5 to 6 hours we have around 4000 machines.

Now we want to deploy all the Hardening policies to  all the domain clients by using a GPO or any scripts to achieve our goal shortly. Is there any possible ways to solve this. Kindly suggest me on this issue. Awaiting for your positive responses.

Thanks,

Lee
