Hello Martin,
I added the Ping explicitly so that program such as Nagios could "ping"
the FD. I have never tried or used it myself, but it should work, and I
think there is a nagios program in the src/examples directory that does
so. The main consideration is that the Ping must be sent using Bacula
communications protocol.
Note: if you really do not want security messages, you should be able to
exclude them in the Messages resource.
Best regards,
Kern

Since the probing is now visible in job logs, it would be useful to have a
safe way of doing this.
Can probes use the Ping message?

Hello,
The Security Alert messages indicate the some one or some process is
probing your FD port but is not using Bacula protocol. It typically
happens with port scanners or programs attempting to see if the Bacula
FD is alive, neither of which are using Bacula communications protocols.
Best regards,
Kern

In backups that ran on 9.4.1 this message is not present. Is there a
functional change in 9.4.2 relevant to this that requires some
configuration change? Or is it a bug?
Here's a complete example job log:
