# Audit Kernel Object
|
||
|
||
**Applies to**
|
||
- Windows 10
|
||
- Windows 10 Mobile
|
||
|
||
This topic for the IT professional describes the Advanced Security Audit policy setting, **Audit Kernel Object**, which determines whether the operating system generates audit events when users attempt to access the system kernel, which includes mutexes and semaphores.
|
||
|
||
Only kernel objects with a matching system access control list (SACL) generate security audit events. The audits generated are usually useful only to developers.
|
||
|
||
Typically, kernel objects are given SACLs only if the **AuditBaseObjects** or **AuditBaseDirectories** auditing options are enabled.
|
||
|
||
> **Note:** The **Audit: Audit the access of global system objects** policy setting controls the default SACL of kernel objects.
|
||
|
||
Event volume: High if you have enabled one of the Global Object Access Auditing settings
|
||
|
||
Default setting: Not configured
|
