Chapter 3 Setting Up the Sensor

Configuring Authentication and User Parameters

Note Enabling RADIUS authentication on the sensor does not disconnect already established connections. RADIUS authentication is only enforced for new connections to the sensor. Existing CLI, IDM, and IME connections remain established with the login credentials used prior to configuring RADIUS authentication. To force disconnection of these established connections, you must reset the sensor after RADIUS is configured.

To configure local or RADIUS AAA authentication on the sensor, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter configuration mode.

sensor# configure terminal

Step 3 Enter AAA submode.

sensor(config)# service aaa sensor(config-aaa)#

Step 4 Configure local authentication. To continue to create users on the local system, enter yes to save your configuration, and use the username command in configure terminal mode. To configure AAA RADIUS authentication, go to Step 5.

sensor(config-aaa)# aaa local

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

Step 5 Configure AAA RADIUS authentication:

a.Enter RADIUS authentication submode.

sensor(config-aaa)# aaa radius sensor(config-aaa-rad)#

b.Enter the Network Access ID. The NAS-ID is an identifier that clients send to servers to communicate the type of service they are attempting to authenticate. The value can be no nas-id, cisco-ips, or a NAS-ID already configured on the RADIUS server. The default is cisco-ips.

sensor(config-aaa-rad)# nas-idcisco-ipssensor(config-aaa-rad)#

c.(Optional) Configure a default user role if you are not configuring a Cisco av pair. You can configure a default user role on the sensor that is only applied when there is NOT a Cisco av pair specifying the user role. The values are unspecified, viewer, operator, or administrator. The default is unspecified.

sensor(config-aaa-rad)#default-user-role operator

sensor(config-aaa-rad)#

Note Service cannot be the default role.

d.Configure a Cisco av pair. If you do not want to configure a default user role on the sensor that is applied in the absence of a Cisco av pair, you need to configure the Cisco IOS/PIX 6.x RADIUS Attributes [009\001] cisco-av-pair under the group or user profile with one of the following options:

ips-role=viewer

ips-role=operator

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.
