Chapter 3. Cisco Adaptive Security Appliance Overview


The Cisco Adaptive Security Appliance (ASA) line combines the functions of a firewall, Virtual Private Network (VPN), and intrusion prevention system (IPS) in a single appliance. This product line is adaptive, which means that it provides several mechanisms that enable the network to be self-defending. The ASA product line is also built to be extensible to add new self-defending capabilities like antivirus, antispam, antiphishing, and antispyware protection, which are supported in the Content Security and Control Security Services Module (CSC-SSM) on the ASA product line.

The ASA product line contains several models, including the Cisco ASA 5505, Cisco ASA 5510, Cisco ASA 5520, Cisco ASA 5540, and the Cisco ASA 5550. Each of these ASA models has a different capacity and price point. The ASA is managed by an easy-to-use Adaptive Security Device Manager (ASDM). ASDM is a follow-on release to the popular PIX Device Manager (PDM). ASDM features several enhancements over PDM, including a near real-time syslog viewer. Figure 3-1 shows the ASDM main screen.

This chapter, which is similar in scope to the other chapters in this book, provides an overview of some of the self-defending components of the ASA product line, with an emphasis on how to manage the device using management products such as the device manager. This chapter is intended to be an overview and a pointer to more detailed or advanced publications, as provided in the References section. In this chapter, you will learn about the antispoofing, IPS, application or protocol inspection, antivirus, antispam, antiphishing, and antispyware protection on the ASA product line.
