> Key: KAFKA-5750

> Project: Kafka
> Issue Type: Improvement
> Components: security
> Reporter: Phillip Walker
> Assignee: Manikumar
> Fix For: 1.0.0
>
>
> Currently, the authorizer logs all messages at DEBUG level and logs every
> single authorization attempt, which can greatly decrease cluster performance,
> especially when Mirrormaker also produces to that cluster. Many InfoSec
> requirements, though, require that authorization denials be logged. The
> proposed solution is to elevate any denial in SimpleAclAuthorizer and any
> other relevant class to WARN while leaving approvals at their currently
> logging levels.
