Intrusion Prevention Services Functional Overview Intrusion Prevention Services Functional Overview The Cisco ASA 5500 series adaptive security appliance supports the AIP SSM, an intrusion prevention services module that monitors and performs real-time analysis of network traffic by looking for anomalies and misuse based on an extensive, embedded signature library. When the system detects unauthorized activity, it can terminate the specific connection, permanently block the attacking host, log the incident, and send an alert to the device manager.

• Getting Started with Your Platform Model This guide applies to multiple security appliance platforms and models: the PIX 500 series security appliances and the ASA 5500 series adaptive security appliances. There are some hardware differences between the PIX and the ASA security appliance. Moreover, the ASA 5505 includes a built-in switch, and requires some special configuration.

Context A, B, and C are unable to reach their 3 percent combined limit. (See Figure 6-2.) Setting unlimited access is similar to oversubscribing the security appliance, except that you have less control over how much you oversubscribe the system. Cisco Security Appliance Command Line Configuration Guide OL-12172-03...
Page 101: Default Class
By default, the default class provides unlimited access to resources for all contexts, except for the following limits, which are by default set to the maximum allowed per context: Telnet sessions—5 sessions. • SSH sessions—5 sessions. • IPSec sessions—5 sessions. • • MAC addresses—65,535 entries. Cisco Security Appliance Command Line Configuration Guide OL-12172-03...
Page 102: Class Members
To set the resource limits, see the following options: Step 2 To set all resource limits (shown in Table 6-1) to be unlimited, enter the following command: • hostname(config-resmgmt)# limit-resource all 0 Cisco Security Appliance Command Line Configuration Guide OL-12172-03...
