Chapter 19 Managing the AIP SSM and CSC SSM

Managing the CSC SSM

Note If you see the preceding license notice (which displays only in some versions of software), you can ignore the message until you need to upgrade the signature files on the AIP SSM. The AIP SSM continues to operate at the current signature level until a valid license key is installed. You can install the license key at a later time. The license key does not affect the current functionality of the AIP SSM.

Step 3 Enter the setup command to run the setup utility for initial configuration of the AIP SSM:

AIP SSM# setup

You are now ready to configure the AIP SSM for intrusion prevention. See the following guides for AIP SSM configuration information

•Configuring the Cisco Intrusion Prevention System Sensor Using the Command Line Interface.

•Command Reference for Cisco Intrusion Prevention System

About the CSC SSM

The ASA 5500 series adaptive security appliance supports the CSC SSM, which runs Content Security and Control software. The CSC SSM provides protection against viruses, spyware, spam, and other unwanted traffic. It accomplishes this by scanning the FTP, HTTP, POP3, and SMTP traffic that you configure the adaptive security appliance to send to it.

Figure 19-1illustrates the flow of traffic through an adaptive security appliance that has the following:

•A CSC SSM installed and setup.

•A service policy that determines what traffic is diverted to the SSM for scans.

In this example, the client could be a network user who is accessing a website, downloading files from an FTP server, or retrieving mail from a POP3 server. SMTP scans differ in that you should configure the adaptive security appliance to scan traffic sent from outside to SMTP servers protected by the adaptive security appliance.

Note The CSC SSM can scan FTP file transfers only when FTP inspection is enabled on the adaptive security appliance. By default, FTP inspection is enabled.
