File hashing

To provide information about file systems, Trellix EDR must first complete the file hashing process to record file system metadata in its databases.

Trellix EDR hashes only non-removable file systems.

On Windows, Trellix EDR hashes only media that return DRIVE_FIXED after calling the GetDriveTypeA function.
On Linux, Trellix EDR hashing ignores all paths that return RM = 1, TYPE = part, MOUNTPOINT != "" after running the command lsblk -o RM,TYPE,MOUNTPOINT -r.
On macOS, Trellix EDR hashing ignores all paths that return the command diskutil info -all and are marked "Removable Drive".

Restrictions

Some restrictions apply to what files are returned by the collector.

Only devices where the user has System Tree permissions reply with results.
Only files that are not excluded by ignore policies appear in search results.
Depending on the database size limit set on file hashing policies, information about files deleted before the past 30 days might not appear in search results.
