Creating Virtual Sensors for the ASA 5500-X IPS SSP

This section describes how to create virtual sensors on the ASA 5500-X IPS SSP, and contains the following topics:

•The ASA 5500-X IPS SSP and Virtualization, page 18-4

•Virtual Sensor Configuration Sequence for ASA 5500-X IPS SSP, page 18-4

•Creating Virtual Sensors, page 18-4

•Assigning Virtual Sensors to Adaptive Security Appliance Contexts, page 18-7

The ASA 5500-X IPS SSP and Virtualization

The ASA 5500-X IPS SSP has one sensing interface, PortChannel 0/0. When you create multiple virtual sensors, you must assign this interface to only one virtual sensor. For the other virtual sensors you do not need to designate an interface.

After you create virtual sensors, you must map them to a security context on the adaptive security appliance using the allocate-ipscommand. You can map many security contexts to many virtual sensors.

Note The allocate-ipscommand does not apply to single mode. In this mode, the adaptive security appliance accepts any virtual sensor named in a policy-mapcommand.

The allocate-ipscommand adds a new entry to the security context database. A warning is issued if the specified virtual sensor does not exist; however, the configuration is allowed. The configuration is checked again when the service-policycommand is processed. If the virtual sensor is not valid, the fail-openpolicy is enforced.

Virtual Sensor Configuration Sequence for ASA 5500-X IPS SSP

Follow this sequence to create virtual sensors on the ASA 5500-X IPS SSP, and to assign them to adaptive security appliance contexts:

1.Configure up to four virtual sensors.

2.Assign the ASA 5500-X IPS SSP sensing interface (PortChannel 0/0) to one of the virtual sensors.

3.(Optional) Assign virtual sensors to different contexts on the adaptive security appliance.

4.Use MPF to direct traffic to the targeted virtual sensor.

Creating Virtual Sensors

Note You can create four 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.
