Hi @montri.m,

Thank you for your post. I would like to clarify based on the logs here that CCMEXEC.EXE is not entirely blocked form running by Self protect. Self protection is designed as the name suggests, to protect McAfee Endpoint Security's own components, process and it's related registries from being tampered with.

Hence this event suggests that our Self protection is trying to Block CCMEXEC.EXE from accessing our processes such as MFETP.EXEMFEFW.EXE and MFEESP.EXE.

if you think it is really required by CCMEXEC.exe to access our process, you can add exclusions to the process under AAC exclusions.

Details here: https://docs.mcafee.com/bundle/endpoint-security-10.6.0-common-product-guide-windows/page/GUID-BE2DE...

However, if this block event does not have any functional impact on the working of the machine, I would recommend against adding the exclusion which may be unnecessary.

I sincerely hope this answer helps your query here 🙂

does anyone know why CCMEXEC.EXE (Microsoft System Centre - Configuration Manager) is trying to control McAfee ?

 

and if we should let it?

This product exists in every second corporation, it should be well understood.

I just found your topic I have the same entries in my selfprotection activity log file.

and good question: "why CCMEXEC.EXE (Microsoft System Centre - Configuration Manager) is trying to control McAfee ?" Misconfiguration or bug in SCCM? My sccm client is 2002

My topic: https://community.mcafee.com/t5/Endpoint-Security-ENS/KB71970-VSE-and-ENS-CcmExec-exe-which-attempte...

This usually occurs due to programmers using the Windows NT Access Right 'Generic_All' instead of only asserting those access rights that are actually necessary to do their jobs.  ccmexec.exe is probably just attempting to inventory the running processes but asserts Generic_All, I suspect, because the programmers of ccmexec.exe didn't take security software into account.

ccmexec.exe has been doing this for decades, along with a lot of other software.  McAfee is legitimately defending itself and I would never reduce security only to avoid event generation.  Instead, if there is a surplus of ePO events just regularly purge the ones related to this phenomenon and you'll sleep at night knowing you're secure from this sort of inadvertent meddling...
