OBJECT_NAME guidelines

Prev Next

Use these guidelines when specifying the OBJECT_NAME match value in a Match_type value. You can use any combination of wildcards.

Note

Exploit Prevention is not supported in the ARM architecture.

OBJECT_NAME value

Notes

Disk name

Accepted formats are:

  • HardDiskXX — HardDisk0

  • $(SystemDrive) — The disk that contains the system volume.

Fully qualified file path

Note

AAC doesn't support short paths.

  • System — Specifies the system process name.

    To match based on the thread running in the system process context, the rule must set an Initiator command to "System".

  • System:Remote — Specifies the system process name for remote systems.

    To match file operations for a remote system, the rule must set an Initiator command to "System:Remote".

To match based on both “System” and “System:Remote”, configure the rule to specify 2 matches or specify “System*”.

Fully qualified registry key/value path

These root keys are recognized:

Key

Matches

HKLM

HKLM is equivalent to HKEY_LOCAL_MACHINE.

HKCU

All user registry keys (not just the current user) and the .default user key.

HKCU is equivalent to:

  • HKEY_CURRENT_USER

  • HKEY_USERS

Note

Matching against specific user SIDs is not supported.

HKCUC

All user classes (HKCU/*_CLASSES).

HKCR

System classes and all user classes (HKCU/*_CLASSES).

HKCR is equivalent to HKEY_CLASSES_ROOT.

HKCCS

  • HKLM/SYSTEM/CurrentControlSet

  • HKLM/SYSTEM/ControlSet00X

HKLMS

  • HKLM/Software on 32-bit and 64-bit systems

  • HKLM/Software/Wow6432Node on 64-bit systems only

HKCUS

  • HKCU/Software on 32-bit and 64-bit systems

  • HKCU/Software/Wow6432Node on 64-bit systems only

HKULM

  • HKLM

  • HKCU

HKULMS

  • HKLMS

  • HKCUS

HKALL

  • HKLM

  • HKU

Note

If the rule specifies a name where the root starts or contains a wild character, the AAC code performs no name normalization and that name might never match correctly. For example, **\mcshield\start is a valid name, but H*L*\mcshield\start is not.

HKEY_CURRENT_CONFIG is not supported.

Fully qualified section name

Process name or fully qualified process path

Process name must also be specified for thread objects.

Volume name

  • Must be specified in the format:

    Volume{35FC9B67-54AC-49ff-AB99-33FFA2999670}

  • $(SystemDrive) — Immutable and always applies to the system volume.
