Introduction

CSC provides an all-in-one malware management solution for your network. The CSC software runs on an SSM that is installed in a compatible Cisco ASA 5500 series adaptive security appliance. The CSC SSM provides the following benefits:

•Detection of and actions to prevent viruses, worms, Trojans, and other threats in your SMTP, POP3, HTTP, and FTP network traffic.

Note Traffic using other protocols, such as HTTPS, is not scanned by CSC.

•Blocking of compressed or very large files that exceed specified parameters.

•Scans for and removal of spyware, adware, and other types of grayware.

The above features are available to all customers with the Base License for CSC. If you purchased the Plus level of the CSC license in addition to the Base License, you also benefit from the following:

•Protection against spam and phishing fraud in your SMTP and POP3 traffic.

•Content filters that enable you to allow or prohibit email traffic containing key words or phrases.

•Blocking of URLs that you do not want employees to access, or URLs that are known to have hidden or malicious purposes.

•Filtering of URL traffic according to predefined categories that you allow/disallow, such as adult/mature content, games, chat/instant messaging, or gambling sites.

With CSC, you do not have to install separate applications for virus protection, spyware blocking, spam detection, or content filtering—all of these functions are available in a single package. CSC provides protection for major traffic protocols—SMTP, HTTP, FTP, and POP3—to ensure that employees do not accidentally introduce viruses from their personal email accounts. And, the application is easy to maintain; after installation and initial configuration, you are unlikely to need to change CSC configuration often.

New Features in CSC Version 6.1

•Network Reputation Service (NRS)—(Was called IP filtering) a real-time blacklist and quick IP lookup technology for identifying spam that frees the MTA from processing the message header during evaluation.

•Trend Micro Control Manager (TMCM) support—enables deployment of uniform configurations across multiple installations of CSC SSM.

•VSAP 8.0—uses the new virus scan engine.

•TMASE 3.5—uses the new anti-spam engine.

•Spyware Recognition—enhanced spyware recognition.

Getting Started with CSC SSM

Before CSC SSM can scan traffic and protect your network from malware, you must perform several configuration steps. These steps include obtaining one or two activation keys by using the Product Authorization Key (PAK) that you should have received with the CSC SSM.

For detailed configuration steps, including how to obtain activation keys, see the "Configuring the CSC SSM" chapter in the Cisco ASA 5500 Series Adaptive Security Appliance Getting Started Guide.

If you are upgrading an activated installation, skip this section.

System Requirements

This section includes the following topics:

•Hardware Requirements

•Client PC Operating System and Browser Requirements

Hardware Requirements

There are two CSC SSM models: CSC SSM 10 and CSC SSM 20. The following adaptive security appliances support both CSC SSM models:

•ASA 5510

•ASA 5520

•ASA 5540

Note CSC SSM licenses support up to 1000 users while the Cisco ASA 5540 Series appliance can support significantly more users. If you deploy CSC SSM with an ASA 5540 adaptive security appliance, be sure to configure the security appliance to send the CSC SSM only the traffic that should be scanned. For guidance with determining what traffic to scan, see the "Managing AIP SSM and CSC SSM" chapter in the Cisco Security Appliance Command Line Configuration Guide.

Client PC Operating System and Browser Requirements

Client access to CSC is supported with ASDM; therefore, the supported and recommended PC operating systems and browsers for Version 6.1 are identical to those for ASDM Version 5.1 and later.

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you will find information about how to:

•Report security vulnerabilities in Cisco products.

•Obtain assistance with security incidents that involve Cisco products.

•Register to receive security information from Cisco.

A current list of security advisories, security notices, and security responses for Cisco products is available at this URL:

http://www.cisco.com/go/psirt

To see security advisories, security notices, and security responses as they are updated in real time, you can subscribe to the Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed. Information about how to subscribe to the PSIRT RSS feed is found at this URL:

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

•For Emergencies only — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

•For Nonemergencies — psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

•1 877 228-7302

•1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
