LAPI
LAPI based whitelist are not your traditional whitelists, as in they wont prevent an overflow from happening, but they will prevent a decision being made by the LAPI this means log processors that forward alerts to the LAPI will not need to be configured individually to ignore certain conditions.
You can create a LAPI based whitelist by prepending a profile to the profiles.yaml file:
name: whitelist
debug: true
filters:
- Alert.GetValue() in ["2.2.2.2", "3.3.3.3"]
on_success: break
---
In this example, the LAPI will not make a decision if the source IP is 2.2.2.2 or 3.3.3.3.
The profiles.yaml file location differs based on the OS type here are the default locations:
- Linux:
/etc/crowdsec/profiles.yaml - FreeBSD:
/usr/local/etc/crowdsec/profiles.yaml - Windows:
C:\ProgramData\CrowdSec\config\profiles.yaml
You can use our extensive EXPR helpers to create more complex whitelists, for example, you can whitelist a range of IPs by using the following syntax:
name: whitelist
debug: true
filters:
- IpInRange(Alert.GetValue(), "192.168.1.0/24")
on_success: break
---
If you have implemented a LAPI based whitelist then you must reload the CrowdSec service for the changes to take effect.
sudo systemctl reload crowdsec
