A file rating determines how Xcitium Client Security (CCS) interacts with a file.
'Trusted' files are safe and are allowed to run normally.
'Untrusted' files are malware, so they get quarantined or deleted.
'Unknown' files are run in the container until they are classified as trusted or untrusted.
File ratings can be set by two entities:
Xcitium- CCS automatically checks the reputation of files on Xcitium's file lookup service (FLS). The FLS contains the very latest trust verdicts from Xcitium’s master blacklists and whitelists.
Local - Local trust verdicts are set by users or admins and are stored in CCS on the endpoint. For example, a user can assign a trust level to a file when answering an alert. Alternatively, an admin can assign a local rating in Endpoint Manager (‘Security Sub-systems’ > ‘Application Control’ > ‘Change Rating’).
Should you wish, you can specify that your endpoints only use ‘Xcitium’ ratings and ignore any local ratings.
Disable the Local Verdict Server in a profile
Open Endpoint Manager
Click ‘Configuration Templates’ > ‘Profiles’
Click the name of the profile you want to edit OR click ‘Create’ to make a new profile
Click the ‘File Rating’ tab
Click ‘Add Profile Section’ > ‘File Rating’ if you have not yet added the section:
Click ‘File Rating’ > ‘Local Verdict Server Settings’ in the file rating section:
Enable Local Verdict Server:
Enabled - CCS will obey the local trust verdict on a file in the event of a conflict with Xcitium’s verdict.
Disabled - CCS will ignore local verdicts and only use Xcitium verdicts to determine the trust level of a file
Clear the ‘Enable Local Verdict Server’ box to disable local verdicts.
Click ‘Save’
Xcitium Client Security will now disregard any local file ratings and will only use Xcitium ratings when deciding how to handle a file.
You can test the interaction between Xcitium and local ratings per file in ‘Security Sub-systems’ > ‘Application Control’:
The example above shows an admin applying a malicious rating to a file, even though the Xcitium rating is ‘Trusted’. CCS will ignore the admin rating if you have disabled the local verdict server as explained earlier.
