Description of problem:
It happened without any action.
SELinux is preventing snort from 'search' accesses on the directory /var/lib/sss.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that snort should be allowed search access on the sss directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep snort /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
