Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Configuring Blocking and Rate Limiting Devices

The Post-Block VACL is best used for additional blocking or permitting that you want to occur on the same VLAN. If you have an existing VACL on the VLAN that the sensor will manage, the existing VACL can be used as a Post-Block VACL. If you do not have a Post-Block V ACL, the sensor inserts permit ip any any at the end of the new VACL.

When the sensor starts up, it reads the contents of the two VACLs. It creates a third VACL with the following entries:

•A permit line for the sensor IP address

•Copies of all configuration lines of the Pre-Block VACL

•A deny line for each address being blocked by the sensor

•Copies of all configuration lines of the Post-Block VACL

The sensor applies the new VACL to the VLAN that you designate.

Note When the new VACL is applied to a VLAN of the switch, it removes the application of any other VACL to that VLAN.

For the procedure for configuring blocking using router ACLs, see Configuring Blocking and Rate Limiting Devices, page 14-21.

Configuring the Sensor to Manage Catalyst 6500 Series Switches and Cisco 7600 Series Routers

To configure the sensor to manage Catalyst 6500 series switches and Cisco 7600 series routers, follow these steps:

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

Step 2 Enter network access submode.

sensor# configure terminal

sensor(config)# service network-access

sensor(config-net)#

Step 3 Specify the IP address for the router controlled by the ARC.

sensor(config-net)# cat6k-devicesip_address

Step 4 Enter the user profile name that you created when you configured the user profile. The ARC accepts anything you type. It does not accept it, check to see if the logical device exists.

sensor(config-net-cat)# profile-nameuser_profile_name

Step 5 Specify the method used to access the sensor. If unspecified, SSH 3DES is used.

sensor(config-net-cat)#communication {telnet ssh-3des}

Note If you are using 3DES, you must use the command ssh host-keyip_address to accept the key or ARC cannot connect to the device.

Step 6 Specify the sensor NAT address.

sensor(config-net-cat)# nat-addressnat_address

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.
