Configure all domain controller to not allow anonymous access to named pipes
To restrict anonymous access to named pipes and shares using Group Policy settings, you can use the Local Group Policy Editor on individual computers or Group Policy Object (GPO) in a domain environment. Here are the steps:
Using Group Policy Object (GPO) in a Domain Environment:
Open the Group Policy Management Console (GPMC) on a domain controller or a computer with GPMC installed.
Create a new GPO or use an existing one that applies to the computers you want to restrict anonymous access on.
Edit the GPO by right-clicking it and selecting "Edit."
Navigate to Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Security Options.
In the right pane, look for the following policies and configure them:
- Network access: Named Pipes that can be accessed anonymously: Set this to "None."
- Network access: Shares that can be accessed anonymously: Set this to "None."
My point is here where there is no option as set this to None. It says Not Defined, and if you want to Define it, you need to go ahead and
and enable "Define this policy in the template" - If you check this then you get few things below like
COMNAP
COMNODE
SQL\QUERY
LLSRPC
BROWSER
Netlogon
So, is it ok to see all this? and if I check this it dos not say anywhere NONE. so, I am confused.
Next, same with -
- Network access: Shares that can be accessed anonymously: Set this to "None."
when I check the box - which states :Define this policy settings in the templates. It shows COMFCFG. Is this correct.
Thanks in advance!
