Just be aware that simple regex would also include undesirable outcomes like null hashes and weak bit strengths, effecting a downgrade attack. You should also explicitly exclude them using something like
nifi.web.https.ciphersuites.exclude=.*128.*,.*NULL.* Or whatever suits your needs. It should be and possibly is a default setting but always best to enforce and note in documentation to stay on top of. I acknowledge it's a pest to set these manually, but that's what tooling like ansible is for, you can do it once and apply to all your Nifi servers easily. Also, even if you did it manually in windows notepad even, the hour spent would cost something like $35-100 whereas the cyber incident could cost hundreds of millions. Never shy putting your hand to the till with mindless administrative tasks that are actually achieving something.
