Chapter 3 Setting Up the Sensor

Configuring Authentication and User Parameters

–ips-role=administrator

–ips-role=service

Note If the sensor is not configured to use a default user role and the sensor user role information in not in the Accept Message of the CiscoSecure ACS server, the sensor rejects RADIUS authentication even if the CiscoSecure ACS server accepts the username and password.

Note The default user role is used only when the user has not been configured with a specific role on the ACS server. Local users are always configured with a specific role so the default user role will never apply to locally authenticated users.

e.Configure the sensor to switch over to local authentication if the RADIUS server becomes unresponsive.

sensor(config-aaa-rad)# local-fallback enabled sensor(config-aaa-rad)#

Step 6 Configure the primary RADIUS server:

a.Enter primary server submode.

sensor(config-aaa-rad)# primary-serversensor(config-aaa-rad-pri)#

b.Enter the RADIUS server IP address.

sensor(config-aaa-rad-pri)# server-address10.1.2.3 sensor(config-aaa-rad-pri)#

c.Enter the RADIUS server port. If not specified, the default RADIUS port is used.

sensor(config-aaa-rad-pri)# server-port 1812

sensor(config-aaa-rad-pri)#

d.Enter the amount of time in seconds you want to wait for the RADIUS server to respond.

sensor(config-aaa-rad-pri)# time-out 5 sensor(config-aaa-rad-pri)#

e.Enter the secret value that you obtained from the RADIUS server. The shared secret is a piece of data known only to the parties involved in a secure communication.

sensor(config-aaa-rad-pri)# shared-secret kkkk sensor(config-aaa-rad-pri)#

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.

Step 7 (Optional) Enable a secondary RADIUS server to perform authentication in case the primary RADIUS server is not responsive:

a.Enter secondary server submode.

sensor(config-aaa-rad)# secondary-server enabled sensor(config-aaa-rad-sec)#

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.
