Configuring Authentication

Chapter 3 Setting Up the Sensor

Configuring Authentication and User Parameters

Step 5 To remove a user, use the no form of the command.

sensor# configure terminal

sensor(config)# no username jsmith

Note You cannot use this command to remove yourself from the system.

Step 6 Verify that the user has been removed. The user jsmith has been removed.

sensor(config)# exit

sensor# show users all

	CLI	ID	User	Privilege
*	13491		cisco	administrator
			jtaylor	service

For More Information

•For the procedure for creating the service account, see Creating the Service Account, page 3-28.

•For the procedure for configuring local or RADIUS authentication, see Configuring Authentication, page 3-20.

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.

You can create and remove users from the local sensor. You can only modify one user account at a time. Each user is associated with a role that controls what that user can and cannot modify. The requirements that must be used for user passwords are set with the password command.

Users are authenticated through AAA either locally or through RADIUS servers. Local authentication is enabled by default. You must configure RADIUS authentication before it is active.

You must specify the user role that is authenticated through RADIUS either by configuring the user role on the RADIUS server or specifying a default user role. The username and password are sent in an authentication request to the configured RADIUS server. The response of the server determines whether the login is authenticated.

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.

You can configure a primary RADIUS server and a secondary RADIUS server. The secondary RADIUS server authenticates and authorizes users if the primary RADIUS server is unresponsive.

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.
