I have been researching this for a little while now and I unfortunately do not have full access to review all the settings for this. From the ENS Help site
https://kc.mcafee.com/corporate/index?page=content&id=KB53735, It reads the following: GTI File Reputation looks for suspicious programs, Portable Document Format (PDF) files, and Android Application Package (.APK) files that are active on endpoints running McAfee products, including Endpoint Security (ENS). In the options section there is a way to disable or enable Cloud Based scanning.
The GTI normally uses a Hash based means of scanning and returning whether or not the file is good, unknown or bad. (Laymens terms here) But in the above snippet it reads as if it sends the .pdf document to the GTI for scanning. Is this true, or is it still just the hash value. I have not been able to find this information anywhere. If it does send the .pdf, is there a way to disable this so that it doesn't send the .pdf and we assume the security risk of not scanning it?
Thank you for any help.
