Device properties

Prev Next

Device properties specify device characteristics such as the device name, bus type, or file system type.

The table provides device property definitions, which definition types use the property, and which operating system they apply to.

Description

Bus Type

All

  • Windows — Bluetooth, Firewire (IEEE1394), IDE/SATA, PCI, PCMIA, SCSI, USB, UAS (USB Attached SCSI)

  • macOS — Firewire (IEEE1394), IDE/SATA, SD, Thunderbolt, USB

Selects the device BUS type from the available list.

Note

For plug-and-play device rules, Trellix DLP Endpoint for Mac only supports USB bus type.

CD/DVD Drives

Removable storage

  • Windows

  • macOS

Select to indicate any CD or DVD drive.

Content encrypted by Endpoint Encryption

Removable storage

Windows

Devices protected with Endpoint Encryption.

Device Class

Plug and Play

Windows

Selects the device class from the available managed list.

Device Compatible IDs

All

Windows

A list of physical device descriptions. Effective especially with device types other than USB and PCI, which are more easily identified using PCI VendorID/DeviceID or USB PID/VID.

Device Instance ID (Microsoft Windows XP)

Device Instance Path (Windows Vista and later Microsoft Windows operating systems, including servers)

All

Windows

A Windows-generated string that uniquely identifies the device in the system.

Example:

USB\VID_0930&PID_6533\5&26450FC&0&6.

Device Friendly Name

All

  • Windows

  • macOS

The name attached to a hardware device, representing its physical address.

File System Type

  • Fixed hard disk

  • Removable storage

  • Windows — CDFS, exFAT, FAT16, FAT32, NTFS, UDFS

  • macOS — CDFS, exFAT, FAT16, FAT32, HFS/HFS+, NTFS, UDFS

macOS supports FAT only on disks other than the boot disk. Mac OS X supports NTFS as read-only.

The type of file system.

  • For hard disks, select one of exFAT, FAT16, FAT32, or NTFS.

  • For removable storage devices, any of the above plus CDFS or UDFS.

File System Access

Removable storage

  • Windows

  • macOS

The access to the file system: read only or read-write.

File System Volume Label

  • Fixed hard disk

  • Removable storage

  • Windows

  • macOS

The user-defined volume label, viewable in Windows Explorer. Partial matching is allowed.

File System Volume Serial Number

  • Fixed hard disk

  • Removable storage

Windows

A 32-bit number generated automatically when a file system is created on the device. It can be viewed by running the command-line command dir x:, where x: is the drive letter.

PCI VendorID / DeviceID

All

Windows

The PCI VendorID and DeviceID are embedded in the PCI device. These parameters can be obtained from the Hardware ID string of physical devices.

Example:

PCI\VEN_8086&DEV_2580&SUBSYS_00000000&REV_04

TrueCrypt devices

Removable storage

Windows

Select to specify a TrueCrypt device.

USB Class Code

Plug and Play

Windows

Identifies a physical USB device by its general function. Select the class code from the available list.

USB Device Serial Number

  • Plug and Play

  • Removable storage

  • Windows

  • macOS

A unique alphanumeric string assigned by the USB device manufacturer, typically for removable storage devices. The serial number is the last part of the instance ID.

Example:

USB\VID_3538&PID_0042\00000000002CD8

A valid serial number must have a minimum of 5 alphanumeric characters and must not contain ampersands (&). If the last part of the instance ID does not follow these requirements, it is not a serial number.

You can enter a partial serial number by using the comparison Contains rather than Equals.

USB Vendor ID / Product ID

  • Plug and Play

  • Removable storage

  • Windows

  • macOS

The USB VendorID and ProductID are embedded in the USB device. These parameters can be obtained from the Hardware ID string of physical devices.

Example:

USB\Vid_3538&Pid_0042
