I am using the Ref Document -

And Trying to build rule - Ref. to one of the Given Example in the document - as below - 

Rule {
service { Include "Alerter" }
application { Include "*"}
user_name { Include "*" }
directives service:stop

- However when I tried to use this on the Client Machine - TmpLogger.BOBl.Activity: Failed to Set Property: Exclusions Error: 0x1


Need to understand -

Re: Exploit Prevention Expert Rule Help


The documentation refers to Windows Services but in case that program runs a process associated with a service you can set a rule addressing that process since they will be dependant

Let me try to answer your questions:

a. It should work with any Windows compatible program/service but you need to follow TCL syntax:

b. Expert Rules are available from ENS 10.5.3 and newer versions so it should work with Win7

c. It should allow you to set an expert rule for any service on a workstation too

In case above information was useful or answered your question, please select "Accept as Solution" in my reply, or give a Kudo. Thanks!

Re: Exploit Prevention Expert Rule Help

Thank you for your reply. I downloaded the TCL & now trying to figure it out - how to use & get the code. 

Anyways - that will take time - I have seen the McAfee documentation - Page - 5 - below details 

++++++++++++++Start of details provided by McAfee Document ++++++++++++++++++++++++++++

AAC-based Expert Rules
AAC is a McAfee proprietary technology that Threat Prevention uses to protect key resources. You can extend
this protection by creating rules to protect specLficfiles, processes, and registry items. AAC-based Expert Rules
use a new syntax used with the Tool Command Language (Tcl) interpreter version 7.6.

++++++++++++++END of details provided by McAfee Document ++++++++++++++++++++++++++++

So now this has created a concern that - look like McAfee has reserved the customization methods. 

What yo say? 

Basically My purpose is to have a Expert Rule - Which can allow me to protect any Service being stop/restart etc. I agree that using the Access Protection we can do the same, however to add additional protection layer - would like to have Expert Rule created for the same. For Folder & Registry Protection - Expert Rule was created with help of above link Document.  

Please suggest.
