Chapter 9 Configuring Anomaly Detection
Configuring the Internal Zone
Configuring the Internal Zone Other Protocols
To configure other protocols for a zone, follow these steps:
Step 1 Log in to the CLI using an account with administrator privileges.
Step 2 Enter anomaly detection internal zone submode.
sensor# configure terminal
sensor(config)# service anomaly-detection ad0
sensor(config-ano)# internal-zone
sensor(config-ano-int)#
Step 3 Enable the other protocols.
sensor(config-ano-int)# other
sensor(config-ano-int-oth)# enabled true
Step 4 Associate a specific number for the other protocols.
sensor(config-ano-int-oth)# protocol-number 5
sensor(config-ano-int-oth-pro)#
Step 5 Enable the service for that port.
sensor(config-ano-int-oth-pro)# enabled true
Step 6 To override the scanner values for that protocol. You can use the default scanner values, or you can
override them and configure your own scanner values.
sensor(config-ano-int-oth-pro)# override-scanner-settings yes
sensor(config-ano-int-oth-pro-yes)#
Step 7 To add a histogram for the new scanner settings. Enter the number of destination IP addresses (low,
medium, or high) and the number of source IP addresses you want associated with this histogram.
sensor(config-ano-int-oth-pro-yes)# threshold-histogram high num-source-ips 75
Step 8 Set the scanner threshold.
sensor(config-ano-int-oth-pro-yes)# scanner-threshold 100
Step 9 Configure the default thresholds for all other unspecified ports.
sensor(config-ano-int-oth-pro-yes)# exit
sensor(config-ano-int-oth-pro)# exit
sensor(config-ano-int-oth)# default-thresholds
sensor(config-ano-int-oth-def)# default-thresholds
sensor(config-ano-int-oth-def)# threshold-histogram medium num-source-ips 120
sensor(config-ano-int-oth-def)# scanner-threshold 120
Step 10 Verify the other configuration settings.
sensor(config-ano-int-oth)# show settings
