Chapter 56 Configuring Threat Detection
Configuring Advanced Threat Detection Statistics
To monitor advanced threat detection statistics, perform one of the following tasks:
Command Purpose
show threat-detection statistics
[min-display-rate min_display_rate] top
[[access-list | host | port-protocol]
[rate-1 | rate-2 | rate-3] |
tcp-intercept [all] detail]]
Displays the top 10 statistics.
The min-display-rate min_display_rate argument limits the display to
statistics that exceed the minimum display rate in events per second. You
can set the min_display_rate between 0 and 2147483647.
If you do not enter any options, the top 10 statistics are shown for all
categories.
To view the top 10 ACEs that match packets, including both permit and
deny ACEs, use the access-list keyword. Permitted and denied traffic are
not differentiated in this display. If you enable basic threat detection using
the threat-detection basic-threat command, you can track access list
denies using the show threat-detection rate acl-drop command.
To view only host statistics, use the host keyword. Note: Due to the threat
detction algorithm, an interface used as a combination failover and state
link could appear in the top 10 hosts; this is expected behavior, and you
can ignore this IP address in the display.
To view statistics for ports and protocols, use the port-protocol keyword.
The port-protocol keyword shows statistics for both ports and protocols
(both must be enabled for the display), and shows the combined statistics
of TCP/UDP port and IP protocol types. TCP (protocol 6) and UDP
(protocol 17) are not included in the display for IP protocols; TCP and
UDP ports are, however, included in the display for ports. If you only
enable statistics for one of these types, port or protocol, then you will only
view the enabled statistics.
To view TCP Intercept statistics, use the tcp-intercept keyword. The
display includes the top 10 protected servers under attack. The all
keyword shows the history data of all the traced servers. The detail
keyword shows history sampling data. The ASA samples the number of
attacks 30 times during the rate interval, so for the default 30 minute
period, statistics are collected every 60 seconds.
The rate-1 keyword shows the statistics for the smallest fixed rate
intervals available in the display; rate-2 shows the next largest rate
interval; and rate-3, if you have three intervals defined, shows the largest
rate interval. For example, the display shows statistics for the last 1 hour,
8 hours, and 24 hours. If you set the rate-1 keyword, the ASA shows only
the 1 hour time interval.
show threat-detection statistics
[min-display-rate min_display_rate] host
[ip_address [mask]]
Displays statistics for all hosts or for a specific host or subnet.
show threat-detection statistics
[min-display-rate min_display_rate] port
[start_port[-end_port]]
Displays statistics for all ports or for a specific port or range of ports.
