> Restrict dangerous processors to special permission
> ---------------------------------------------------
>
> Key: NIFI-3050
> URL: https://issues.apache.org/jira/browse/NIFI-3050
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Affects Versions: 1.0.0
> Reporter: Andy LoPresto
> Assignee: Andy LoPresto
> Priority: Blocker
> Labels: security
> Fix For: 1.1.0
>
>
> As evidenced by [NIFI-3045] and other discoveries (e.g. using an
> {{ExecuteScript}} processor to iterate over a {{NiFiProperties}} instance
> after the application has already decrypted the sensitive properties from the
> {{nifi.properties}} file on disk, using a {{GetFile}} processor to retrieve
> {{/etc/passwd}}, etc.) NiFi is a powerful tool which can allow unauthorized
> users to perform malicious actions. While no tool as versatile as NiFi will
> ever be completely immune to insider threat, to further restrict the
> potential for abuse, certain processors should be designated as
> {{restricted}}, and these processors can only be added to the canvas or
> modified by users who, along with the proper permission to modify the canvas,
> have a special permission to interact with these "dangerous" processors.
> From the [Security Feature
> Roadmap|https://cwiki.apache.org/confluence/display/NIFI/Security+Feature+Roadmap]:
> {quote}
> Dangerous Processors
> * Processors which can directly affect behavior/configuration of NiFi/other
> services
> - {{GetFile}}
> - {{PutFile}}
> - {{ListFile}}
> - {{FetchFile}}
> - {{ExecuteScript}}
> - {{InvokeScriptedProcessor}}
> - {{ExecuteProcess}}
> - {{ExecuteStreamCommand}}
> * These processors should only be creatable/editable by users with special
> access control policy
> * Marked by {{@Restricted}} annotation on processor class
> * All flowfiles originating/passing through these processors have special
> attribute/protection
> * Perhaps *File processors can access a certain location by default but
> cannot access the root filesystem without special user permission?
> {quote}
> [~mcgilman] and I should have a PR for this tomorrow.
