Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Configuring the Sensor to be a Master Blocking Sensor

If the master blocking sensor requires TLS for web connections, you must configure the ARC of the blocking forwarding sensor to accept the X.509 certificate of the master blocking sensor remote host. Sensors by default have TLS enabled, but you can change this option.

Note Typically the master blocking sensor is configured to manage the network devices. Blocking forwarding sensors are not normally configured to manage other network devices, although doing so is permissible.

Even if you have no devices configured for blocking or rate limiting, a sensor that is configured for blocking or rate limiting can forward blocking and rate limiting requests to a master blocking sensor. When a signature fires that has blocking or rate limit requests configured as event actions, the sensor forwards the block or rate limit request to the master blocking sensor, which then performs the block or rate limit.

Caution Only one sensor should control all blocking interfaces on a device.

Use the master-blocking-sensorsmaster_blocking_sensor_ip_address command in the service network access submode to configure a master blocking sensor.

The following options apply:

•master_blocking_sensor_ip_address—Specifies the IP address of sensor for forward block requests.

•password—Specifies the account password of sensor for forward block requests.

•port—Specifies the port of sensor for forward block requests.

•tls {true false} —Set to true if the remote sensor requires TLS; otherwise, set to false.

•username—Specifies the account name of sensor for forward block requests.

Configuring the Master Blocking Sensor

To configure ARC on a sensor to forward blocks to a master blocking sensor, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges on both the master blocking sensor and the blocking forwarding sensor.

Step 2 Enter configuration mode on both sensors.

sensor# configure terminal

Step 3 Configure TLS if necessary:

a.On the master blocking sensor, check to see if it requires TLS and what port number is used. If enable-tlsis true, go to Step b.

sensor(config)# service web-server sensor(config-web)#show settings enable-tls: true <defaulted>

port: 443 <defaulted>

server-id: HTTP/1.1 compliant <defaulted> sensor(config-web)#

b.On the blocking forwarding sensor, configure it to accept the X.509 certificate of the master blocking sensor.

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.
