Configuring Application Layer Protocol Inspection

This chapter describes how to configure application layer protocol inspection. Inspection engines are

required for services that embed IP addressing information in the user data packet or that open secondary

channels on dynamically assigned ports. These protocols require the security appliance to do a deep

packet inspection instead of passing the packet through the fast path. As a result, inspection engines can

affect overall throughput.

Several common inspection engines are enabled on the security appliance by default, but you might need

to enable others depending on your network. This chapter includes the following sections:

• Inspection Engine Overview, page 24-2

–

When to Use Application Protocol Inspection, page 24-2

The DHCP server is enabled on the adaptive security appliance, so a computer connecting to the interface receives an address between 192.168.1.2 and 192.168.1.254. The HTTP server is enabled for ASDM and is accessible to users on the 192.168.1.0 network.
