Description

When you implement different security policies for traffic from different customers or departments, you can use the virtualization features available on the Cisco ASA adaptive security appliance. You can configure several security contexts, each acting as a separate virtual security appliance on the same physical hardware. On each security context, you can configure most of the features that are available on single-mode Cisco ASA security appliances. This course describes the security contexts feature and how to configure and manage multiple security contexts.
You can deploy Cisco ASA adaptive security appliances in an active/active high-availability failover to provide device redundancy and load sharing in order to increase performance. Using this active/active failover feature, you can pair two security appliances, in which both devices process traffic at the same time and act as a backup for each other. When both devices are operational, each processes a share of network traffic, depending on your traffic routing configuration. If one of the two appliances fails, the other takes over and processes all network traffic. This course describes the active/active failover feature and how to configure, tune, and troubleshoot active/active failover functionality.
