IPS and Advanced Protocol
Handling
The primary function of the Cisco Security Appliance is to prevent and to protect internal
hosts from malicious attacks from the outside network. Some hackers try to gain access
to the internal network, but others attack network resources to disrupt network services.
This chapter describes some of the features of the Cisco Security Appliance that are used
to mitigate known attacks against network resources. This chapter also discusses how the
Security Appliance handles multimedia application protocols.
