Identity firewall - The ASA provides optional granular access control based on an association of IP addresses to Windows Active Directory login information.

Both platforms must be identical in software, licensing, memory, and interfaces, including the Security Services Module (SSM). The status of the active ASA device is monitored over the LAN failover interface by the standby ASA. One of the ASAs is elected to be in active state (forwarding traffic) and the other in hot standby state (waiting). One physical device is designated as primary, the other as secondary. High availability with failover - Two identical ASAs can be paired into an active / standby failover configuration to provide device redundancy. Some features are not supported, including VPN and dynamic routing protocols. Many features are supported in multiple context mode, including routing tables, firewall features, IPS, and management. Multiple contexts are similar to having multiple standalone devices. Each context is an independent device, with its own security policy, interfaces, and administrators. Each virtual device is called a security context. ASA virtualization - A single ASA can be partitioned into multiple virtual devices. Other advanced ASA features include these: Three security features do ASA models 55 support by default:

Previously, these functions were available in three separate devices, each with its own software and hardware. The ASA software combines firewall, VPN concentrator, and intrusion prevention functionality into one software image. The traditional Finesse/PIX OS combination. Beginning with PIX OS version 8.x, the operating system codeĭiverges, with the ASA using a Linux kernel and PIX continuing to use Through PIX OS release 7.x the PIX and the ASA use the same software

The ASA series of devices run PIX code 7.0 and later. Which combines functionality from the PIX, VPN 3000 series and IPS In May 2005, Cisco introduced the Adaptive Security Appliance (ASA) The choice of ASA model will depend on an organization's requirements, such as maximum throughput, maximum connections per second, and budget. the maximum traffic throughput supported,Ĭisco ASA devices scale to meet a range of requirements and network sizes. The biggest difference between the models is the maximum traffic throughput handled by each model and the number and type of interfaces. There are six ASA models, ranging from the basic 5505 branch office model to the 5585 data center version. It delivers superior scalability, a broad range of technology and solutions, and effective, always-on security designed to meet the needs of a wide array of deployments. The Cisco ASA 5500 series is a primary component of the Cisco Secure Borderless Network. The IOS firewall solution does not scale well and typically cannot meet the needs of a large enterprise.Ĭisco provides two firewall solutions: the firewall-enabled ISR and the Cisco Adaptive Security Appliance (ASA).
