# Sysmon Event ID 10: Process Access
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
**Caution:** Collecting Sysmon events without a tailored configuration for your environment will cause high data volume. These setup instructions would need significant tuning in order to be production-ready. For more specific configurations, we recommend you to explore the following resources:
|
||
|
|
- https://github.com/trustedsec/SysmonCommunityGuide
|
||
|
|
- https://github.com/olafhartong/sysmon-modular
|
||
|
|
- https://github.com/Neo23x0/sysmon-config
|
||
|
|
|
||
|
|
Some detection rules require the use of Sysmon Event ID 10 (Process Accessed) events to detect malicious activity, such as credential dumping from `lsass.exe`.
|
||
|
|
|
||
|
|
To collect these logs, use the [Windows Integration](https://www.elastic.co/docs/current/integrations/windows) and select the `Sysmon Operational` channel on the integration setup page.
|
||
|
|
|
||
|
|
## Configuration Example
|
||
|
|
|
||
|
|
The following example demonstrates a more targeted approach for Event ID 10 by focusing specifically on attempts to access the `lsass.exe` process. Based on https://github.com/Neo23x0/sysmon-config/blob/1fdc5f837e06bcf95a42f0c8d49ea311fde628a3/sysmonconfig-export.xml#L517C4-L520C11
|
||
|
|
|
||
|
|
```xml
|
||
|
|
<Sysmon schemaversion="4.90">
