Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Configuring the Sensor to be a Master Blocking Sensor

Example

sensor(config)# tls trusted-host ip-address 192.0.2.1 port 8080

Certificate MD5 fingerprint is F4:4A:14:BA:84:F4:51:D0:A4:E2:15:38:7E:77:96:D8Certificate SHA1 fingerprint is 84:09:B6:85:C5:43:60:5B:37:1E:6D:31:6A:30:5F:7E:4D:4D:E8:B2

Would you like to add this to the trusted certificate table for this host?[yes]:

Note You are prompted to accept the certificate based on the certificate fingerprint. Sensors provide only self-signed certificates (instead of certificates signed by a recognized certificate authority). You can verify the master blocking sensor host sensor certificate by logging in to the host sensor and typing the show tls fingerprint command to see that the fingerprints of the host certificate match.

Step 4 Enter yes to accept the certificate from the master blocking sensor.

Step 5 Enter network access mode.

sensor(config)# service network-access

Step 6 Enter general submode.

sensor(config-net)# general

Step 7 Add a master blocking sensor entry.

sensor(config-net-gen)#master-blocking-sensorsmaster_blocking_sensor_ip_address

Step 8 Specify the username for an administrative account on the master blocking sensor host.

sensor(config-net-gen-mas)# username username

Step 9 Specify the password for the user.

sensor(config-net-gen-mas)# password

Enter password []: *****

Re-enter mbs-password []: *****

sensor(config-net-gen-mas)#

Step 10 Specify the port number for the host HTTP communications. The default is 80/443 if not specified.

sensor(config-net-gen-mas)# port port_number

Step 11 Specify whether or not the host uses TLS/SSL.

sensor(config-net-gen-mas)# tls {true false}

sensor(config-net-gen-mas)

Note If you set the value to true, you need to use the command tls trusted-hostip-addressmaster_blocking_sensor_ip_address.

Step 12 Exit network access submode.

sensor(config-net-gen-mas)# exit sensor(config-net-gen)# exit sensor(config-net)# exit

sensor(config)# exit Apply Changes:?[yes]:

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.
