Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Configuring Blocking and Rate Limiting Devices

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

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

Note This changes the IP address in the first line of the ACL from the address of the sensor to the NAT address. This is not a NAT address configured on the device being managed. It is the address the sensor is translated to by an intermediate device, one that is between the sensor and the device being managed.

Step 7 Specify whether the router will perform blocking, rate limiting, or both.

Note The default is blocking. You do not have to configure response capabilities if you want the router to perform blocking only.

a.Rate limiting only

sensor(config-net-rou)#response-capabilities rate-limit

 

 

 

 

 

 

b. Both blocking and rate limiting

 

 

 

 

 

 

sensor(config-net-rou)#response-capabilities blockrate-limit

 

 

 

 

Step 8

Specify the interface name and direction.

 

 

 

 

 

 

sensor(config-net-rou)#block-interfaces interface_name {in out}

 

 

 

 

 

 

 

 

 

 

Caution

The name of the interface must either be the complete name of the interface or an abbreviation that the

 

 

 

 

 

 

router recognizes with the interface command.

 

 

 

 

 

 

 

 

 

 

Step 9

(Optional) Add the pre-ACL name (blocking only).

 

 

 

 

 

 

sensor(config-net-rou-blo)# pre-acl-namepre_acl_name

 

 

 

 

Step 10

(Optional) Add the post-ACL name (blocking only).

 

 

 

 

 

 

sensor(config-net-rou-blo)# post-acl-namepost_acl_name

 

 

 

 

Step 11

Verify the settings.

 

 

 

 

 

 

sensor(config-net-rou-blo)# exit

 

 

 

 

 

 

sensor(config-net-rou)# show settings

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.
