Chapter 3 Setting Up the Sensor

Configuring Authentication and User Parameters

•primary-server—Lets you configure the main RADIUS server:

–server-address—IP address of the RADIUS server.

–server-port—Port of the RADIUS server. If not specified, the default RADIUS port is used.

–timeout (seconds)—Specifies the number of seconds the sensor waits for a response from a RADIUS server before it considers the server to be unresponsive.

–shared-secret—The secret value configured on the RADIUS server. You must obtain the secret value of the RADIUS server to enter with the shared-secretcommand.

Note You must have the same secret value configured on both the RADIUS server and the IPS sensor so that the server can authenticate the requests of the client and the client can authenticate the responses of the server.

•secondary-server {enabled disabled}— (Optional) Lets you configure a secondary RADIUS server:

–server-address—IP address of the RADIUS server.

–server-port—Port of the RADIUS server. If not specified, the default RADIUS port is used.

–timeout (seconds)—Specifies the number of seconds the sensor waits for a response from a RADIUS server before it considers the server to be unresponsive.

–shared-secret—The secret value configured on the RADIUS server. You must obtain the secret value of the RADIUS server to enter with the shared-secretcommand.

Note You must have the same secret value configured on both the RADIUS server and the IPS sensor so that the server can authenticate the requests of the client and the client can authenticate the responses of the server.

•console-authentication—Lets you choose how users connected through the console port are authenticated:

–local—Users connected through the console port are authenticated through local user accounts.

–radius-and-local—Users connected through the console port are authenticated through RADIUS first. If RADIUS fails, local authentication is attempted. This is the default.

–radius—Users connected through the console port are authenticated by RADIUS. If you also have local-fallbackenabled, users can also be authenticated through the local user accounts.

Configuring Local or RADIUS Authentication

Caution Make sure you have a RADIUS server already configured before you configure RADIUS authentication on the sensor. IPS has been tested with CiscoSecure ACS 4.2 and 5.1 servers. Refer to your RADIUS server documentation for information on how to set up a RADIUS server.

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.
