cscli collections install mstilkerich/bind9A collection for bind9
This collection should address the same events as the fail2ban named-refused jail.
Acquisition configuration depends on whether bind9 is configured to log to syslog, separate log files, or both.
For a separate log file, set the log type to named:
1filenames:2 - /var/log/named/security.log3labels:4 type: named
If you are using syslog, set type to syslog instead.
