# Thresholding:
|
|
#
|
|
# This feature is used to reduce the number of logged alerts for noisy rules.
|
|
# Thresholding commands limit the number of times a particular event is logged
|
|
# during a specified time interval.
|
|
#
|
|
# The syntax is the following:
|
|
#
|
|
# threshold gen_id <gen_id>, sig_id <sig_id>, type <limit|threshold|both>, track <by_src|by_dst>, count <n>, seconds <t>
|
|
#
|
|
# event_filter gen_id <gen_id>, sig_id <sig_id>, type <limit|threshold|both>, track <by_src|by_dst>, count <n>, seconds <t>
|
|
#
|
|
# suppress gen_id <gid>, sig_id <sid>
|
|
# suppress gen_id <gid>, sig_id <sid>, track <by_src|by_dst>, ip <ip|subnet>
|
|
#
|
|
# The options are documented at https://suricata.readthedocs.io/en/latest/configuration/global-thresholds.html
|
|
#
|
|
# Please note that thresholding can also be set inside a signature. The interaction between rule based thresholds
|
|
# and global thresholds is documented here:
|
|
# https://suricata.readthedocs.io/en/latest/configuration/global-thresholds.html#global-thresholds-vs-rule-thresholds
|
|
|
|
# Limit to 10 alerts every 10 seconds for each source host
|
|
#threshold gen_id 0, sig_id 0, type threshold, track by_src, count 10, seconds 10
|
|
|
|
# Limit to 1 alert every 10 seconds for signature with sid 2404000
|
|
#threshold gen_id 1, sig_id 2404000, type threshold, track by_dst, count 1, seconds 10
