9800-40 security violation

What keys? SSID keys, Guest users keys, or management keys?

Management sees this in syslog but I don't see anything in the gui.

- Normally this is seen if any RSA key is configured with a bit size less than 2048 bits , you could use this
as 'search criteria' on your keys,

Well I have not been informed about a continuation of the issue after I updated the key

Thank you.

Whenever possible (all latest IOS) you should use 4096. Takes a few seconds longer to generate (depending on CPU) but makes it a bit more future proof for when they next raise the threshold.
