Configuring Scanning Threat Detection
Detailed Steps
Monitoring Shunned Hosts, Attackers, and Targets
To monitor shunned hosts and attackers and targets, perform one of the following tasks:
Command
Purpose
Step 1
threat-detection scanning-threat 
[shun 
[except {ip-address ip_address mask | 
object-group
 network_object_group_id}]]
Example:
ciscoasa(config)# threat-detection 
scanning-threat shun except ip-address 
10.1.1.0 255.255.255.0
Enables scanning threat detection. By default, the system log 
message 733101 is generated when a host is identified as an 
attacker. Enter this command multiple times to identify multiple 
IP addresses or network object groups to exempt from shunning.
Step 2
threat-detection scanning-threat shun 
duration 
seconds
Example:
ciscoasa(config)# threat-detection 
scanning-threat shun duration 2000
(Optional) Sets the duration of the shun for attacking hosts.
Step 3
threat-detection rate scanning-threat 
rate-interval
 rate_interval average-rate 
av_rate burst-rate burst_rate
Example:
ciscoasa(config)# threat-detection rate 
scanning-threat rate-interval 1200 
average-rate 10 burst-rate 20
ciscoasa(config)# threat-detection rate 
scanning-threat rate-interval 2400 
average-rate 10 burst-rate 20
(Optional) Changes the default event limit for when the ASA 
identifies a host as an attacker or as a target. If you already 
configured this command as part of the basic threat detection 
configuration (see the 
), then those settings are shared 
with the scanning threat detection feature; you cannot configure 
separate rates for basic and scanning threat detection. If you do 
not set the rates using this command, the default values are used 
for both the scanning threat detection feature and the basic threat 
detection feature. You can configure up to three different rate 
intervals, by entering separate commands.
Command
Purpose

Displays the hosts that are currently shunned.
