Enable McAfee Global Threat
Intelligence file reputation
with
Sensitivity level
Enables McAfee Global Threat Intelligence file reputation on your appliance.
McAfee Global Threat Intelligence file reputation complements the
DAT-based signatures by providing the appliances access to millions of
cloud-based signatures. This reduces the delay between McAfee detecting a
new malware threat and its inclusion in DAT files, providing broader coverage.
The sensitivity levels enable you to balance the risk of missing potentially
harmful content (low settings) with the risk of false positive detections
(high settings).
For gateway appliances, the recommended sensitivity level is Medium.
Attempt to clean When selected, the infection inside the item is removed, if possible. When
deselected, the entire item is removed.
If cleaning succeeds
Provides several actions after cleaning succeeds.
If cleaning fails Provides several actions if the cleaning failed.
Use the default alert When selected, issues the default alert upon detection. When deselected,
allows you to click the link, then change the text of the alert.
And also
Provides several further actions.
If a file is zero bytes after
cleaning
Provides an action against a file that is now empty. Zero-byte files cannot
carry threats but you might prefer to remove the files if they confuse users.
Make deobfuscated content
available to other scanners
When selected, provides extra protection against unwanted content. The
techniques that detect hidden viruses and malware are made available to
content scanning.
