# Disallow unknown image registries
|
|
|
|
|
|
2019-10-23 22:36:37 +00:00
|
|
|
Images from unknown registries may not be scanned and secured. Requiring the use of trusted registries helps reduce threat exposure.
|
|
|
|
|
|
|
|
|
|
You can customize this policy to allow image registries that you trust.
