Chapter 19 Configuring the ASA 5500-X IPS SSP
Creating Virtual Sensors for the ASA 5500-X IPS SSP
• description—Provides a description of the virtual sensor.
• event-action-rules—Specifies the name of the event action rules policy.
• signature-definition—Specifies the name of the signature definition policy.
• physical-interfaces—Specifies the name of the physical interface.
• no—Removes an entry or selection.
Creating Virtual Sensors
To create a virtual sensor on the ASA 5500-X IPS SSP, follow these steps:
Step 1 Log in to the CLI using an account with administrator privileges.
Step 2 Enter service analysis mode.
sensor# configure terminal
sensor(config)# service analysis-engine
sensor(config-ana)#
Step 3 Add a virtual sensor.
sensor(config-ana)# virtual-sensor vs1
sensor(config-ana-vir)#
Step 4 Add a description for this virtual sensor.
sensor(config-ana-vir)# description virtual sensor 1
Step 5 Assign an anomaly detection policy and operational mode to this virtual sensor if you have enabled
anomaly detection. If you do not want to use the default anomaly detection policy, ad0, you must create
a new one using the service anomaly-detection name command, for example, ad1.
sensor(config-ana-vir)# anomaly-detection
sensor(config-ana-vir-ano)# anomaly-detection-name ad0
sensor(config-ana-vir-ano)# operational-mode learn
Step 6 Assign an event action rules policy to this virtual sensor. If you do not want to use the default event action
rules policy, rules0, you must create a new one using the service event-action-rules name command, for
example, rules1
sensor(config-ana-vir-ano)# exit
sensor(config-ana-vir)# event-action-rules rules0
Step 7 Assign a signature definition policy to this virtual sensor. If you do not want to use the default signature
definition policy, sig0, you must create a new one using the service signature-definition name
command, for example sig1.
sensor(config-ana-vir)# signature-definition sig0
Step 8 Assign the interface to one virtual sensor. By default the sensing interface is already assigned to the
default virtual sensor, vs0. You must remove it from the default virtual sensor to assign it to another
virtual sensor that you create.
sensor(config-ana-vir)# physical-interface PortChannel0/0
Step 9 Verify the virtual sensor settings.
sensor(config-ana-vir)# show settings
<protected entry>
name: vs1
