Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Supported Devices

Before you configure the ARC for blocking or rate limiting, make sure you do the following:

•Analyze your network topology to understand which devices should be blocked by which sensor, and which addresses should never be blocked.

•Gather the usernames, device passwords, enable passwords, and connections types (Telnet or SSH) needed to log in to each device.

•Know the interface names on the devices.

•Know the names of the Pre-Block ACL or VACL and the Post-Block ACL or VACL if needed.

•Understand which interfaces should and should not be blocked and in which direction (in or out). You do not want to accidentally shut down an entire network.

For More Information

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

Supported Devices

Caution If the recommended limits are exceeded, the ARC may not apply blocks in a timely manner or may not be able to apply blocks at all.

By default, the ARC supports up to 250 devices in any combination. The following devices are supported for blocking by the ARC:

•Cisco series routers using Cisco IOS 11.2 or later (ACLs):

–Cisco 1600 series router

–Cisco 1700 series router

–Cisco 2500 series router

–Cisco 2600 series router

–Cisco 2800 series router

–Cisco 3600 series router

–Cisco 3800 series router

–Cisco 7200 series router

–Cisco 7500 series router

•Catalyst 5000 switches with RSM with IOS 11.2(9)P or later (ACLs)

•Catalyst 6500 switches and 7600 routers with IOS 12.1(13)E or later (ACLs)

•Catalyst 6500 switches 7600 routers with Catalyst software version 7.5(1) or later (VACLs)

–Supervisor Engine 1A with PFC

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.
