Add drive_type and drive_type_id under File Object

[02manoj92]

The proposal is to extend the File Object by adding details about the type of drive where the file is located. This enrichment would offer greater security insight, assisting the SOC team in determining whether files are created off a network drive or say a USB thumb drive.
Some advantages if this is added:

• Better file activity tracking
• Data Compliance and Governance
• Improved incident response

We can add two optional fields called drive_type and drive_type_id under File Object to take care of this.
drive_type_id can take one of the following values :
0 = "Unknown", 1 = "Removable", 2 = "Fixed", 3 = "Remote", 4 = "CD-ROM", 5 = "Ram Disk", 99 = "Other"
and the drive_type would be string equivalent.

Example : If a user creates a file on a Windows network share say \\10.0.2.3\public\users\testusers\ocsf_file_create.exe, the File System Activity can include the File Object with drive_type_id as 3 and drive_type as Remote

"Removable" (e.g., USB drives)
"Fixed" (e.g., internal hard drives)
"Remote" (e.g., network drives)
"CD-ROM" (e.g., optical drives)
"RAM Disk" (e.g., temporary storage in RAM)
"Other" (for any other types not specifically listed)
