how to get audit rule in acl object with getauditrules() on registry key in powershell?

问题

I am trying to apply audit rules with this code

function add-acl($Right,$Access)
{
$audit = "mydomain\myaccount","$Right","containerinherit","none","$Access"
$r = new-object system.security.accesscontrol.registryauditrule $audit
$acl.addauditrule($r)
}

$acl = get-acl hklm:\software\_test
add-acl "CreateSubKey" "Success"
add-acl "Delete" "Success"  
add-acl "Delete" "Failure"  
$acl | set-acl

but this code writes audit rules without taking account of earlier rules. So I wanted to retrieve audit rules before applying the code. To do so, I used the method getauditrules() :

$acl.getauditrules($true,$true,??)

In ?? position, I tried NTaccount object and windowsSecurity. It doesn't return an error and in fact does not return something at all. This is really disapointing because while using windows interface, I can see that an audit rule is applied. I don't understand what type of object is expecting the getauditrules() method. Can someone help me ?

回答1:

Try adding the -audit paramenter to get-acl cmdlet ( this retrieve SACL , System Access Control List).

$acl = get-acl hklm:\software\_test -audit

the you can use:

$acl.getauditrules($true,$true, [System.Security.Principal.NTAccount] )

or

$acl.getauditrules($true,$true, [System.Security.Principal.SecurityIdentifier] )

based on your goal.
