# Check Settings
Each check can be assigned a severity. Only checks with a severity of danger or warning will be validated. The results of these validations are visible on the dashboard. In the case of the validating webhook, only failures with a severity of danger will result in a change being rejected.
Polaris validation checks fall into several different categories:
To change the default severity levels, or to turn checks on or off, you can create your own config.yaml:
checks:
tagNotSpecified: ignore
runAsRootAllowed: danger
pullPolicyNotAlways: warning
