title: How to use restricted NiFi processors?
body: <p>I want to use NiFi processors that are listed as restricted. Although I have searched for information, I can't quite understand how they work. I have found some information here:
  <a href="https://community.cloudera.com/t5/Community-Articles/NIFI-RESTRICTED-COMPONENTS-POLICY-DESCRIPTIONS/ta-p/249157" rel="nofollow noreferrer">https://community.cloudera.com/t5/Community-Articles/NIFI-RESTRICTED-COMPONENTS-POLICY-DESCRIPTIONS/ta-p/249157</a></p>
  <p>I understand that they are processors that could execute code and therefore be unsafe for the system. And that you need permission to use them. But I can't quite understand if they are insecure for my application and my data or NiFi. I don't really understand what they mean in the article by &quot;Users can only be restricted from adding such components in NiFi if NiFi has been secured. Users of an unsecured NiFi will always have access to all components.&quot;</p>
  <p>In the end, it does not clarify much for me. I want to know if I can use them without exposing the security of my application or if I need permission to use them. And if you need permits, how do you get them?</p>
  <p>Excuse me, I am totally new to NiFi, I have literally put 5 simple processors in.</p>
