Appendix A System Architecture

SwitchApp

Caution You receive a warning message if you have enabled global correlation, but you have not configured a DNS or HTTP proxy server. This warning is a reminder to either disable global correlation or add a DNS or HTTP proxy server.

For More Information

For the procedure for adding a DNS or proxy server to support global correlation, see Changing Network Settings, page 3-2.

Error Events

Whenever a global correlation update fails, an evError event is generated. The error message is included in sensor statistics. The following conditions result in a status message with the severity of Error:

The sensor is unlicensed

No DNS or HTTP proxy server is configured

The manifest exchange failed

An update file download failed

Applying or committing the update failed

An evError event is generated with the severity level of Warning if you edit and save either the host or global correlation configurations so that global correlation is enabled, but no DNS or HTTP proxy servers are configured.

For More Information

For the procedure for displaying sensor statistics, see Displaying Statistics, page 17-28.

SwitchApp

The 4500 series sensors have a built in switch that provides the external monitoring interfaces of the sensor. The SwitchApp is part of the IPS 4500 series design that enables the InterfaceApp and sensor initialization scripts to communicate with and control the switch. Any application that needs to get or set information on the switch must communicate with the SwitchApp. Additionally the SwitchApp implements the following:

Detects bypass—When the SensorApp is not monitoring, the SwitchApp places the switch in bypass mode and then back to inspection mode once the SensorApp is up and running normally.

Collects port statistics—The SwitchApp monitors the switch and collects statistics on the external interfaces of the switch for reporting by InterfaceApp.

Handles the external interface configuration—When you update the interface configuration, the configuration is sent to the InterfaceApp, which updates the interface configuration for SwitchApp, which then forwards that configuration on to the switch.

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.
