New features for your virtual environment
The new virtualization features include the following:
■ Shared Insight Cache
The Symantec Endpoint Protection Shared Insight Cache reduces the need to scan files in a virtualized environment that Symantec Endpoint Protection has determined are clean. Shared Insight Cache runs independently of Symantec Endpoint Protection. However, you must configure Symantec Endpoint Protection Manager to specify the location of Shared Insight Cache so that your clients can communicate with it.
No special license is required to install or run Shared Insight Cache.
■ Virtual Image Exclusion
Instead of continually scanning system files for viruses, the Virtual Image Exclusion tool lets you whitelist files from your baseline image on virtual machines. You run the Virtual Image Exclusion tool from the command line. However, you must also configure Symantec Endpoint Protection Manager so that your clients skip the whitelisted files.
■ Hypervisor detection
Symantec Endpoint Protection Manager now automatically detects which clients are virtual, as well as their virtual platform. This feature lets you not only know more about your clients, it also lets you create policies for virtual machine groups and search for virtual clients.
■ Symantec offline image scanner
The Symantec offline image scanner can scan offline VMware .vmdk files to ensure that there are no threats in the image.
