The Lite signature set is a lightweight version of the signature set, a version moderated by Trellix IPS researchers. This is to make sure the oldest signatures are excluded without posing an appreciable risk to modern day attacks. Exclusion of older signatures allows you to continue updating your Sensors with the latest attack signatures while keeping the memory use relatively low.
Note
The lite signature sets are available only in the Download Server upon entering your Grant number.
Following are the steps to update the signature set with the lightweight version:
Download the Lite signature set file (.ivu) from the Trellix Download Server.
Select Manager → <Admin Domain Name> → Trellix IPS Protection Status. Then, select Manual Import tab.
The Manual Import tab is displayed.
