Chapter 3 Installing the IPS 4240 and IPS 4255

Product Overview

Note The illustrations in this chapter show the Cisco IPS 4240 appliance sensor. The IPS 4240 and the IPS 4255 look identical with the same front and back panel features and indicators.

Note In IPS 7.1, rx/tx flow control is disabled on the IPS 4240 and the IPS 4255. This is a change from IPS 7.0 where rx/tx flow control is enabled by default.

Caution The BIOS on IPS 4240 and the IPS 4255 is specific to IPS 4240 and the IPS 4255 and must only be upgraded under instructions from Cisco with BIOS files obtained from the Cisco website. Installing a non-Cisco or third-party BIOS on these sensors voids the warranty. For more information on how to obtain instructions and BIOS files from the Cisco website, see Obtaining Cisco IPS Software, page C-1.

Product Overview

The IPS 4240 and IPS 4255 deliver high port density in a small form factor. They use a compact flash device for storage rather than the hard-disk drives used in other sensor models.

Note The IPS 4240 and the IPS 4255 do not support redundant power supplies.

The IPS 4240 replaces the IDS 4235. There are four 10/100/1000 copper sensing interfaces. The IPS 4240 is available with either AC or DC power. It monitors up to 250 Mbps of aggregate network traffic on multiple sensing interfaces and is inline ready. The 250-Mbps performance for IPS 4240 is based on the following conditions:

•2500 new TCP connections per second

•2500 HTTP transactions per second

•Average packet size of 445 bytes

•Running Cisco IPS 5.1 or later

Note The 250-Mbps performance is traffic combined from all four sensing interfaces.

The IPS 4255 replaces the IDS 4250-TX. There are four 10/100/1000 copper sensing interfaces. It monitors up to 600 Mbps of aggregate network traffic on multiple sensing interfaces and is also inline ready. The 600-Mbps performance for the IPS 4255 is based on the following conditions:

•6000 new TCP connections per second

•6000 HTTP transactions per second

•Average packet size of 445 bytes

•Running Cisco IPS 5.1 or later

Note The 600-Mbps performance is traffic combined from all four sensing interfaces.

IPS4520K9 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.
