Chapter 10 Configuring Global Correlation

Global Correlation Requirements

Global Correlation Requirements

Global correlation has the following requirements:

•Valid license—You must have a valid sensor license for global correlation features to function. You can still configure and display statistics for the global correlation features, but the global correlation databases are cleared and no updates are attempted. Once you install a valid license, the global correlation features are reactivated.

•Network Participation disclaimer—You must agree to the disclaimer to participate.

•External connectivity for the sensor and a DNS server—The global correlation features of Cisco IPS require the sensor to connect to the Cisco SensorBase Network. Domain name resolution is also required for these features to function. You can either configure the sensor to connect through an HTTP proxy server that has a DNS client running on it, or you can assign an Internet routeable address to the management interface of the sensor and configure the sensor to use a DNS server. In Cisco IPS the HTTP proxy and DNS servers are used only by the global correlation features.

•If you are connecting through an HTTP proxy, make sure you have the following configuration:

–The proxy must allow HTTP requests from the IPS systems to http://updates.ironport.com/ibrs/ on port 80.

–The proxy must allow HTTPS requests from the IPS systems to update-manifests.ironport.com on port 443.

–The firewall must allow access from the proxy to the internet (any destination address) on ports 80 and 443.

•If you are NOT connecting through the HTTP proxy:

–The firewall must allow access from each IPS to the Internet (any destination address) on ports 80 and 443.

Note The IPS does not support the use of authenticated proxies.

•Sensors deployed in an environment with a slow command and control connection will be slow to download global correlation updates.

•No IPv6 address support—Global correlation inspection and the reputation filtering deny features do not support IPv6 addresses. For global correlation inspection, the sensor does not receive or process reputation data for IPv6 addresses. The risk rating for IPv6 addresses is not modified for global correlation inspection. Similarly, network participation does not include event data for attacks from IPv6 addresses. And finally, IPv6 addresses do not appear in the deny list.

•Sensor in inline mode—The sensor must operate in inline mode so that the global correlation features can increase efficacy by being able to use the inline deny actions.

•Sensor that supports the global correlation features

•IPS version that supports the global correlation features

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.
