Add the name and description of the file.
Name
The list name may only consist of the characters a-z, A-Z and 0-9. Note: No Spaces.
Description
You may enter a description here for your reference (not parsed).
    NOTE:   The threshold keyword is deprecated as of version 2.8.5. Use the event_filter keyword instead.
Apply suppression or filters to rules. Valid keywords are 'suppress', 'event_filter' and 'rate_filter'.
Example 1; suppress gen_id 1, sig_id 1852, track by_src, ip 10.1.1.54
Example 2; event_filter gen_id 1, sig_id 1851, type limit, track by_src, count 1, seconds 60
Example 3; rate_filter gen_id 135, sig_id 1, track by_src, count 100, seconds 1, new_action log, timeout 10
