Information About the CSC SSM
Some ASA models support the CSC SSM, which runs Content Security and Control software. The CSC SSM provides protection against viruses, spyware, spam, and other unwanted traffic by scanning the FTP, HTTP/HTTPS, POP3, and SMTP packets that you configure the ASA to send to it.
For more information about the CSC SSM, see the following URL:
Figure 64-1 shows the flow of traffic through an ASA that has the following:
•A CSC SSM installed and configured.
•A service policy that determines what traffic is diverted to the CSC SSM for scanning.
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 ASA to scan traffic sent from the outside to SMTP servers protected by the ASA.
Flow of Scanned Traffic with the CSC SSM
You use ASDM for system setup and monitoring of the CSC SSM. For advanced configuration of content security policies in the CSC SSM software, you access the web-based GUI for the CSC SSM by clicking links within ASDM. The CSC SSM GUI appears in a separate web browser window. To access the CSC SSM, you must enter the CSC SSM password. To use the CSC SSM GUI, see the Cisco Content Security and Control (CSC) SSM Administrator Guide.
Note ASDM and the CSC SSM maintain separate passwords. You can configure their passwords to be identical; however, changing one of these two passwords does not affect the other password.
The connection between the host running ASDM and the ASA is made through a management port on the ASA. The connection to the CSC SSM GUI is made through the SSM management port. Because these two connections are required to manage the CSC SSM, any host running ASDM must be able to reach the IP address of both the ASA management port and the SSM management port.
Figure 64-2 shows an ASA with a CSC SSM that is connected to a dedicated management network. While use of a dedicated management network is not required, we recommend it. In this configuration, the following items are of particular interest:
•An HTTP proxy server is connected to the inside network and to the management network. This HTTP proxy server enables the CSC SSM to contact the Trend Micro Systems update server.
•The management port of the ASA is connected to the management network. To allow management of the ASA and the CSC SSM, hosts running ASDM must be connected to the management network.
•The management network includes an SMTP server for e-mail notifications for the CSC SSM and a syslog server to which the CSC SSM can send syslog messages.
CSC SSM Deployment with a Management Network
Determining What Traffic to Scan
The CSC SSM can scan FTP, HTTP/HTTPS, POP3, and SMTP traffic only when the destination port of the packet requesting the connection is the well-known port for the specified protocol. The CSC SSM can scan only the following connections:
•FTP connections opened to TCP port 21.
•HTTP connections opened to TCP port 80.
•HTTPS connections opened to TCP port 443.
•POP3 connections opened to TCP port 110.
•SMTP connections opened to TCP port 25.
You can choose to scan traffic for all of these protocols or any combination of them. For example, if you do not allow network users to receive POP3 e-mail, do not configure the ASA to divert POP3 traffic to the CSC SSM. Instead, block this traffic.
To maximize performance of the ASA and the CSC SSM, divert only the traffic to the CSC SSM that you want the CSC SSM to scan. Diverting traffic that you do not want scanned, such as traffic between a trusted source and destination, can adversely affect network performance.
Note When traffic is first classified for CSC inspection, it is flow-based. If traffic is part of a pre-existing connection, the traffic goes directly to the service policy set for that connection.
You can apply service policies that include CSC scanning globally or to specific interfaces; therefore, you can choose to enable CSC scans globally or for specific interfaces. For more information, see the "Determining Service Policy Rule Actions for CSC Scanning" section.
Based on the configuration shown in Figure 64-3, configure the ASA to divert to the CSC SSM only requests from clients on the inside network for HTTP, FTP, and POP3 connections to the outside network, and incoming SMTP connections from outside hosts to the mail server on the DMZ network. Exclude from scanning HTTP requests from the inside network to the web server on the DMZ network.
Figure 64-3 Common Network Configuration for CSC SSM Scanning
There are many ways you could configure the ASA to identify the traffic that you want to scan. One approach is to define two service policies: one on the inside interface and the other on the outside interface, each with access lists that match traffic to be scanned.
Figure 64-4 shows service policy rules that select only the traffic that the ASA should scan.
Figure 64-4 Optimized Traffic Selection for CSC Scans
In the inside-policy, the first class, inside-class1, ensures that the ASA does not scan HTTP traffic between the inside network and the DMZ network. The Match column indicates this setting by displaying the "Do not match" icon. This setting does not mean the ASA blocks traffic sent from the 192.168.10.0 network to TCP port 80 on the 192.168.20.0 network. Instead, this setting exempts the traffic from being matched by the service policy applied to the inside interface, which prevents the ASA from sending the traffic to the CSC SSM.
The second class of the inside-policy, inside-class matches FTP, HTTP, and POP3 traffic between the inside network and any destination. HTTP connections to the DMZ network are exempted because of the inside-class1 setting. As previously mentioned, policies that apply CSC scanning to a specific interface affect both incoming and outgoing traffic, but by specifying 192.168.10.0 as the source network, inside-class1 matches only connections initiated by the hosts on the inside network.
In the outside-policy, outside-class matches SMTP traffic from any outside source to the DMZ network. This setting protects the SMTP server and inside users who download e-mail from the SMTP server on the DMZ network, without having to scan connections from SMTP clients to the server.
If the web server on the DMZ network receives files uploaded by HTTP from external hosts, you can add a rule to the outside policy that matches HTTP traffic from any source to the DMZ network. Because the policy is applied to the outside interface, the rule would only match connections from HTTP clients outside the ASA.

Guidelines and Limitations
This section includes the guidelines and limitations for this feature.
Context Mode Guidelines
Supported in single and multiple context modes.
Firewall Mode Guidelines
Supported in routed and transparent firewall modes.
Does not support sessions in Stateful Failover. The CSC SSM does not maintain connection information, and therefore cannot provide the failover unit with the required information. The connections that a CSC SSM is scanning are dropped when the ASA in which the CSC SSM is installed fails. When the standby ASA becomes active, it forwards the scanned traffic to the CSC SSM and the connections are reset.
Does not support IPv6.
Supported on the ASA 5510, ASA 5520, and ASA 5540 only.
You cannot change the software type installed on the module; if you purchase a CSC module, you cannot later install IPS software on it.

Configuring the CSC SSM
This section describes how to configure the CSC SSM and includes the following topics:
•Before Configuring the CSC SSM
•Connecting to the CSC SSM
•Determining Service Policy Rule Actions for CSC Scanning
Before Configuring the CSC SSM
Before configuring the ASA and the CSC SSM, perform the following steps:
Step 1 If the CSC SSM did not come preinstalled in a Cisco ASA, install it and connect a network cable to the management port of the SSM. For assistance with installation and connecting the SSM, see the Cisco ASA 5500 Series Adaptive Security Appliance Getting Started Guide.
The management port of the CSC SSM must be connected to your network to allow management of and automatic updates to the CSC SSM software. Additionally, the CSC SSM uses the management port for e-mail notifications and syslog messages.
Step 2 You should have received a Product Authorization Key (PAK) with the CSC SSM. Use the PAK to register the CSC SSM at the following URL.
After you register, you receive activation keys by e-mail. The activation keys are required before you can complete Step 6.
Step 3 Obtain the following information for use in Step 6:
•CSC SSM management port IP address, netmask, and gateway IP address
•DNS server IP address
•HTTP proxy server IP address (needed only if your security policies require the use of a proxy server for HTTP access to the Internet)
•Domain name and hostname for the CSC SSM
•An e-mail address, and SMTP server IP address and port number for e-mail notifications
•E-mail address(es) for product license renewal notifications
•IP addresses of hosts or networks that are allowed to manage the CSC SSM
•Password for the CSC SSM
Step 4 In a web browser, access ASDM for the ASA in which the CSC SSM is installed.
Note If you are accessing ASDM for the first time, see the "Additional References" section.
For more information about enabling ASDM access, see the "Configuring ASA Access for ASDM, Telnet, or SSH" section.
Step 5 Verify time settings on the ASA. Time setting accuracy is important for logging of security events and for automatic updates of CSC SSM software. Do one of the following:
•If you manually control time settings, verify the clock settings, including time zone. Choose Configuration > Properties > Device Administration > Clock.
•If you are using NTP, verify the NTP configuration. Choose Configuration > Properties > Device Administration > NTP.
Step 6 Open ASDM.
Step 7 Connect to and log in to the CSC SSM. For instructions, see the "Connecting to the CSC SSM" section.
Step 8 Run the CSC Setup Wizard.
•To access the CSC Setup Wizard, choose Configuration > Trend Micro Content Security > CSC Setup > Wizard Setup > Launch Setup Wizard.
•If you are rerunning the CSC Setup Wizard, perform the same step listed in the previous bullet.
The CSC Setup Wizard appears.
Step 9 Complete the CSC Setup Wizard, which includes configuration of service policies to divert traffic that you want scanned to the CSC SSM.
Note If you create a global service policy to divert traffic for CSC scans, all traffic (inbound and outbound) for the supported protocols is scanned. To maximize performance of the ASA and the CSC SSM, scan traffic only from untrusted sources.
Step 10 To reduce the load on the CSC SSM, configure the service policy rules that send packets to the CSC SSM to support only HTTP/HTTPS, SMTP, POP3, or FTP traffic. For instructions, see the "Determining Service Policy Rule Actions for CSC Scanning" section.
Step 11 (Optional) Review the default content security policies in the CSC SSM GUI, which are suitable for most implementations. You review the content security policies by viewing the enabled features in the CSC SSM GUI. For the availability of features, see the "Licensing Requirements for the CSC SSM" section. For the default settings, see the "Default Settings" section.
What to Do Next
See the "Connecting to the CSC SSM" section.
Connecting to the CSC SSM
With each session you start in ASDM, the first time you access features related to the CSC SSM, you must specify the management IP address and provide the password for the CSC SSM. After you successfully connect to the CSC SSM, you are not prompted again for the management IP address and password. If you start a new ASDM session, the connection to the CSC SSM is reset and you must specify the IP address and the CSC SSM password again. The connection to the CSC SSM is also reset if you change the time zone on the ASA.
Note The CSC SSM has a password that is maintained separately from the ASDM password. You can configure the two passwords to be identical, but changing the CSC SSM password does not affect the ASDM password.
To connect to the CSC SSM, perform the following steps:
Step 1 In the ASDM main application window, click the Content Security tab.
Step 2 In the Connecting to CSC dialog box, click one of the following radio buttons:
•To connect to the IP address of the management port on the SSM, click Management IP Address. ASDM automatically detects the IP address for the SSM in the ASA. If this detection fails, you can specify the management IP address manually.
•To connect to an alternate IP address or hostname on the SSM, click Other IP Address or Hostname.
Step 3 Enter the port number in the Port field, and then click Continue.
Step 4 In the CSC Password field, type your CSC password, and then click OK.
Note If you have not completed the CSC Setup Wizard (choose Configuration > Trend Micro Content Security > CSC Setup > Wizard Setup), complete the configuration in the CSC Setup Wizard, which includes changing the default password, "cisco."
For ten minutes after you have entered the password, you do not need to reenter the CSC SSM password to access other parts of the CSC SSM GUI.
Step 5 To access the CSC SSM GUI, choose Configuration > Trend Micro Content Security, and then click one of the following tabs: Web, Mail, File Transfer, or Updates.
What to Do Next
See the "Determining Service Policy Rule Actions for CSC Scanning" section.
Determining Service Policy Rule Actions for CSC Scanning
The CSC SSM scans only HTTP/HTTPS, SMTP, POP3, and FTP traffic. If your service policy includes traffic that supports other protocols in addition to these four, packets for other protocols are passed through the CSC SSM without being scanned. You should configure the service policy rules that send packets to the CSC SSM to support only HTTP/HTTPS, SMTP, POP3, or FTP traffic.
The CSC Scan tab in the Add Service Policy Rule Wizard lets you determine whether or not the CSC SSM scans traffic identified by the current traffic class. This tab appears only if a CSC SSM is installed in the ASA.
To configure service policy rules for CSC scanning, perform the following steps:
Step 1 In the ASDM main application window, choose Configuration > Firewall > Service Policy Rules.
Step 2 On the toolbar, click Add.
The Add Service Policy Rule Wizard screen appears.
Step 3 Click the Global - applies to all interfaces option, and then click Next.
The Traffic Classification Criteria screen appears.
Step 4 Click the Create a new traffic class option, type a name for the traffic class in the adjacent field, check the Any traffic check box, and then click Next.
The Rule Actions screen appears.
Step 5 Click the CSC Scan tab, and then check the Enable CSC scan for this traffic flow check box.
Step 6 Choose whether the ASA should permit or deny selected traffic to pass if the CSC SSM is unavailable by making the applicable selection in the area labeled: If CSC card fails, then. When this check box is checked, the other parameters on this tab become active.
Step 7 In the If CSC card fails area, if the CSC SSM becomes inoperable, choose one of the following actions:
•To allow traffic, check the Permit traffic check box.
•To block traffic, check the Close traffic check box.
Step 8 Click Finish.
The new service policy rule appears in the Service Policy Rules pane.
Step 9 Click Apply.
The ASA begins diverting traffic to the CSC SSM, which performs the content security scans that have been enabled according to the license that you purchased.

Troubleshooting the CSC Module
This section includes procedures that help you recover or troubleshoot the module and includes the following topics:
•Installing an Image on the Module
•Resetting the Password
•Reloading or Resetting the Module
•Shutting Down the Module
Note This section covers all ASA module types; follow the steps appropriate for your module.
Installing an Image on the Module
If the module suffers a failure, and the module application image cannot run, you can reinstall a new image on the module from a TFTP server.
Note Do not use the upgrade command within the module software to install the image.
Be sure the TFTP server that you specify can transfer files up to 60 MB in size.
Note This process can take approximately 15 minutes to complete, depending on your network and the size of the image.
hw-module module 1 recover configure
hostname# hw-module module 1 recover configure
Image URL [tftp://127.0.0.1/myimage]: tftp://10.1.1.1/ids-newimg
Port IP Address [127.0.0.2]: 10.1.2.10
Port Mask [255.255.255.254]: 255.255.255.0
Gateway IP Address [18.104.22.168]: 10.1.2.254
VLAN ID : 100
Specifies the location of the new image. This command prompts you for the URL for the TFTP server, the management interface IP address and netmask, gateway address, and VLAN ID (ASA 5505 only). These network parameters are configured in ROMMON; the network parameters you configured in the module application configuration are not available to ROMMON, so you must set them separately here.
You can view the recovery configuration using the show module 1 recover command.
In multiple context mode, enter this command in the system execution space.
hw-module module 1 recover boot
hostname# hw-module module 1 recover boot
Transfers the image from the TFTP server to the module and restarts the module.
hostname# show module 1 details
Checks the progress of the image transfer and module restart process.
The Status field in the output indicates the operational status of the module. A module operating normally shows a status of "Up." While the ASA transfers an application image to the module, the Status field in the output reads "Recover." When the ASA completes the image transfer and restarts the module, the newly transferred image is running.
Resetting the Password
You can reset the module password to the default. The default password is cisco. After resetting the password, you should change it to a unique value using the module application.
Resetting the module password causes the module to reboot. Services are not available while the module is rebooting.
If you cannot connect to ASDM with the new password, restart ASDM and try to log in again. If you defined a new password and still have an existing password in ASDM that is different from the new password, clear the password cache by choosing File > Clear ASDM Password Cache, then restart ASDM and try to log in again.
To reset the module password to the default of cisco, perform the following steps.
Step 1 From the ASDM menu bar, choose Tools > CSC Password Reset.
The Password Reset confirmation dialog box appears.
Step 2 Click OK to reset the password to the default.
A dialog box displays the success or failure of the password reset.
Step 3 Click Close to close the dialog box.
Reloading or Resetting the Module
To reload or reset the module, enter one of the following commands at the ASA CLI.
hw-module module 1 reload
hostname# hw-module module 1 reload
Reloads the module software.
hostname# hw-module module 1 reset
Performs a reset, and then reloads the module.
Shutting Down the Module
If you restart the ASA, the module is not automatically restarted. To shut down the module, perform the following steps at the ASA CLI.
hw-module module 1 shutdown
hostname# hw-module module 1 shutdown
Shuts down the module.
