Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Configuring Blocking and Rate Limiting Devices

Note The ARC reads the lines in the ACL and copies these lines to the beginning of the ACL.

3.Any active blocks.

4.Either specify a Post-Block ACL, which must already exist on the device, or specify permit ip any any (do not use if a Post-Block ACL is specified). The ARC reads the lines in the ACL and copies these lines to the end of the ACL.

Note Make sure the last line in the ACL is permit ip any any if you want all unmatched packets to be permitted.

The ARC uses two ACLs to manage devices. Only one is active at any one time. It uses the offline ACL name to build the new ACL, then applies it to the interface. The ARC then reverses the process on the next cycle.

Caution The ACLs that the ARC makes should never be modified by you or any other system. These ACLs are temporary and new ACLs are constantly being created by the sensor. The only modifications that you can make are to the Pre- and Post-Block ACLs.

If you need to modify the Pre-Block or Post-Block ACL, do the following:

1.Disable blocking on the sensor.

2.Make the changes to the configuration of the device.

3.Reenable blocking on the sensor.

When blocking is reenabled, the sensor reads the new device configuration.

Caution A single sensor can manage multiple devices, but you cannot use multiple sensors to control a single device. In this case, use a master blocking sensor.

For More Information

•For the procedure for enabling blocking, see Configuring Blocking Properties, page 14-7.

•For the procedure for configuring the sensor to be a master blocking sensor, see Configuring the Sensor to be a Master Blocking Sensor, page 14-28.

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.
