Chapter 18 Configuring the ASA 5500-X IPS SSP

Creating Virtual Sensors for the ASA 5500-X IPS SSP

Assigning Virtual Sensors to Adaptive Security Appliance Contexts

After you create virtual sensors on the ASA 5500-X IPS SSP, you must assign the virtual sensors to a security context on the adaptive security appliance.

The following options apply:

•[no] allocate-ipssensor_name [mapped_name] [default]—Allocates a virtual sensor to a security context. Supported modes are multiple mode, system context, and context submode.

Note You cannot allocate the same virtual sensor twice in a context.

–sensor_name—Specifies the name of the virtual sensor configured on the ASA 5500-X IPS SSP. You receive a warning message if the name is not valid.

–mapped_name—Specifies the name by which the security context knows the virtual sensor.

Note The mapped name is used to hide the real name of the virtual sensor from the context, usually done for reasons of security or convenience to make the context configuration more generic. If no mapped name is used, the real virtual sensor name is used. You cannot reuse a mapped name for two different virtual sensors in a context.

–no—De-allocates the sensor, looks through the policy map configurations, and deletes any IPS subcommand that refers to it.

–default—Specifies this virtual sensor as the default. All legacy IPS configurations that do not specify a virtual sensor are mapped to this virtual sensor.

Caution You can only configure one default virtual sensor per context. You must turn off the default flag of an existing default virtual sensor before you can designate another virtual sensor as the default.

–clear configure allocate-ips—Removes the configuration.

–allocate-ips?—Displays the list of configured virtual sensors.

•show context [detail]—Updated to display information about virtual sensors. In user context mode, a new line is added to show the mapped names of all virtual sensors that have been allocated to this context. In system mode, two new lines are added to show the real and mapped names of virtual sensors allocated to this context.

You can assign multiple virtual sensors to a context. Multiple contexts can share one virtual sensor, and when sharing, the contexts can have different mapped names (aliases) for the same virtual sensor. The following procedure demonstrates how to add three security contexts in multiple mode and how to assign virtual sensors to these security contexts.

Assigning Virtual Sensors to Contexts

To assign virtual sensors to adaptive security appliance contexts in multiple mode for the

ASA 5500-X IPS SSP, follow these steps:

Step 1 Log in to the adaptive security appliance.

Step 2 Display the list of available virtual sensors.

IPS4510K9 specifications

Cisco Systems has long been a leading player in network security, and its IPS (Intrusion Prevention System) series is a testament to its commitment to safeguarding digital environments. Among its notable offerings are the IPS4510K9 and IPS4520K9 models, both designed to provide advanced threat protection for mid-sized to large enterprise networks.

The Cisco IPS4510K9 and IPS4520K9 are distinguished by their cutting-edge features that help organizations defend against a myriad of cyber threats. These systems utilize a multi-layered approach to security, integrating intrusion prevention, advanced malware protection, and comprehensive visibility across the network.

One of the primary characteristics of the IPS4510K9 is its high performance. It boasts a throughput of up to 1 Gbps, making it suitable for environments that demand rapid data processing and real-time responses to threats. The IPS4520K9, on the other hand, enhances that capability with improved throughput of up to 2 Gbps, accommodating larger enterprises with heavier network traffic. These models are equipped with powerful processors that support complex signature matching and can intelligently distinguish between legitimate traffic and potential threats.

In addition to performance, both models are designed with scalability in mind. They can be easily integrated into existing Cisco infrastructures. This facilitates a seamless enhancement of security without causing significant interruptions to ongoing operations. Moreover, they offer flexible deployment options, allowing organizations to operate them inline or out of band depending on their specific needs.

The Cisco IPS4510K9 and IPS4520K9 leverage advanced detection technologies, utilizing a variety of signature types and heuristic analysis to detect known and unknown threats effectively. They are equipped with real-time alerting and reporting capabilities, giving security teams immediate visibility into potential breaches and enabling them to respond swiftly.

Furthermore, both models support a range of management options through the Cisco Security Manager, allowing for centralized administration, streamlined policy management, and enhanced monitoring capabilities. Automated updates ensure the systems remain current with the latest threat intelligence, vital for staying ahead of evolving cyber threats.

In summary, the Cisco Systems IPS4510K9 and IPS4520K9 represent powerful solutions for organizations seeking robust intrusion prevention capabilities. With their high performance, scalability, and advanced detection technologies, these systems are essential tools in the ever-changing landscape of cybersecurity, providing enterprises with the peace of mind needed to operate securely in today's digital world.
