Chapter 18 Configuring the ASA 5500-X IPS SSP

Creating Virtual Sensors for the ASA 5500-X IPS SSP

Use the virtual-sensorname command in service analysis engine submode to create virtual sensors on the ASA 5500-X IPS SSP. You assign policies (anomaly detection, event action rules, and signature definition) to the virtual sensor. You can use the default policies, ad0, rules0, or sig0, or you can create new policies.Then you assign the sensing interface, PortChannel 0/0 for the ASA 5500-X IPS SSP to one virtual sensor.

The following options apply:

•anomaly-detection—Specifies the anomaly detection parameters:

–anomaly-detection-namename—Specifies the name of the anomaly detection policy.

–operational-mode—Specifies the anomaly detection mode (inactive, learn, detect).

Note Anomaly detection is disabled by default. You must enable it to configure or apply an

anomaly detection policy. Enabling anomaly detection results in a decrease in performance.

•description—Provides a description of the virtual sensor.

•event-action-rules—Specifies the name of the event action rules policy.

•signature-definition—Specifies the name of the signature definition policy.

•physical-interfaces—Specifies the name of the physical interface.

•no—Removes an entry or selection.

Creating Virtual Sensors

To create a virtual sensor on the ASA 5500-X IPS SSP, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter service analysis mode.

sensor# configure terminal sensor(config)# service analysis-engine sensor(config-ana)#

Step 3 Add a virtual sensor.

sensor(config-ana)# virtual-sensor vs1 sensor(config-ana-vir)#

Step 4 Add a description for this virtual sensor.

sensor(config-ana-vir)#description virtual sensor 1

Step 5 Assign an anomaly detection policy and operational mode to this virtual sensor if you have enabled anomaly detection. If you do not want to use the default anomaly detection policy, ad0, you must create a new one using the service anomaly-detectionname command, for example, ad1.

sensor(config-ana-vir)# anomaly-detectionsensor(config-ana-vir-ano)# anomaly-detection-name ad0 sensor(config-ana-vir-ano)# operational-mode learn

Step 6 Assign an event action rules policy to this virtual sensor. If you do not want to use the default event action rules policy, rules0, you must create a new one using the service event-action-rulesname command, for example, rules1

sensor(config-ana-vir-ano)# exit

sensor(config-ana-vir)#event-action-rules rules0

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.
