Appendix A System Architecture

CLI

CLI

The CLI provides the sensor user interface for all direct node access such as Telnet, SSH, and serial interface. You configure the sensor applications with the CLI. Direct access to the underlying OS is allowed through the service role. This section describes the IPS CLI, and contains the following topics:

•User Roles, page A-30

•Service Account, page A-31

User Roles

Caution You should carefully consider whether you want to create a service account. The service account provides shell access to the system, which makes the system vulnerable. However, you can use the service account to create a password if the administrator password is lost. Analyze your situation to decide if you want a service account existing on the system.

There are four user roles:

•Viewer—Can view configuration and events, but cannot modify any configuration data except their user passwords.

•Operator—Can view everything and can modify the following options:

–Signature tuning (priority, disable or enable)

–Virtual sensor definition

–Managed routers

–Their user passwords

•Administrator—Can view everything and can modify all options that operators can modify in addition to the following:

–Sensor addressing configuration

–List of hosts allowed to connect as configuration or viewing agents

–Assignment of physical sensing interfaces

–Enable or disable control of physical interfaces

–Add and delete users and passwords

–Generate new SSH host keys and server certificates

•Service—Only one user with service privileges can exist on a sensor. The service user cannot log in to the IDM or the IME. The service user logs in to a bash shell rather than the CLI.

The service role is a special role that allows you to bypass the CLI if needed. Only one service account is allowed. You should only create an account with the service role for troubleshooting purposes. Only a user with administrator privileges can edit the service account.

When you log in to the service account, you receive the following warning:

************************ WARNING *************************************************

UNAUTHORIZED ACCESS TO THIS NETWORK DEVICE IS PROHIBITED.

This account is intended to be used for support and troubleshooting purposes only. Unauthorized modifications are not supported and will require this device to be re-imaged to guarantee proper operation.

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.
