Cisco IPS - Intrusion Prevention System
In today's busy network environment, business continuity relies on effective network intrusion prevention to stop malicious attacks, worms, and application abuse before they affect your data and resources. Cisco® IPS 4200 Series Sensors and Cisco IPS Sensor Software are core components of Cisco's intrusion prevention solution. Using Cisco IPS Sensor Software's inline prevention technology, Cisco IPS 4200 Series Sensors accurately detect, classify, and stop malicious traffic on IPv4 and IPv6 networks.
Cisco IPS 4200 Series Sensors deliver high-performance intelligent detection with precision response, extending the diverse Cisco IPS solution from the network edge to the data center for both IPv4 and IPv6 networks.
Cisco IPS 4200 Series Sensors accurately identify, classify, and stop malicious traffic before it affects your business.
• Cisco IPS technology is engineered to prevents malicious activity, including worms, directed attacks, distributed denial of service attacks, reconnaissance, and application abuse.
• Built on advanced Cisco security and network intelligence, modular inspection capabilities can detect and prevent threats to the entire network stack, from applications to Address Resolution Protocol (ARP). Cisco IPS technology extends this expertise by providing industry-leading protection from evasion.
• Cisco IPS provides adaptive vulnerability and anomaly detection. Signatures are focused on vulnerabilities, so your ability to detect threats remains intact, even as exploits change. For emerging "zero-day" threats, a Cisco IPS sensor learns about your network, detects behavioral anomalies, and mitigates attacks without a signature update.
• Cisco IPS is the only intrusion prevention systems that use Global Correlation. Global Correlation harnesses the power of Cisco Security Intelligence Operations, the world's largest threat monitoring network, to achieve unprecedented threat management efficacy. Global threat information is turned into actionable intelligence, such as reputation scores, and pushed out to all enabled technologies. Using Global Correlation, Cisco IPS can stop twice the amount of malicious activity that traditional signature-only IPS technologies can, and with fewer false positives. With Global Correlation updates every five minutes, the Cisco IPS can also adjust to changing threat conditions 100 times faster than signature updates alone.
• Cisco IPS technology and signature services are developed by an extensive global team of Cisco security experts. These experts conduct ongoing research into emerging threats, inspection methods, and prevention strategies, in order to continue to deliver up-to-date vulnerability-based signatures and advanced intrusion prevention capabilities.
Cisco IPS 4200 Series Sensors deliver precision threat-impact analysis, enabling you to respond to threats with confidence.
• Cisco IPS sensors provide you with the most knowledge of potential threat impact by calculating a real-time measurement of risk for every event. An adaptive multidimensional algorithm combines attack and attacker details with live global and network knowledge to produce a calibrated risk measurement.
• Cisco IPS sensors have the richest set of response actions for flexible and precise response policies. You can tailor your IPS policy to each network environment and threat-directly dropping packets, terminating sessions, and rate limiting, or implementing access control and rate limiting on routers and other security appliances throughout the network.
• Cisco IPS threat rating assesses post-response residual risk, enabling incident handlers to focus on the highest-impact events. Risk measurements are updated following an active response to prioritize events with the greatest potential to impact your business.
• Cisco IPS sensors record live, in-depth information on every alert, enabling incident handlers to rapidly diagnose and resolve events. Context data and session logging provide packet-level detail before, during, and after each event.

• Cisco IPS 4200 Series Sensors are designed to withstand failures and minimize downtime, giving you the assurance that your IPS solutions can bear the most strenuous peaks of your day-to-day operations.
• Built-in, comprehensive monitoring detects potential failures at every level of operation, including devices, services, communications, and monitoring link failures.
• Automated and manual fail-open options enable you to define the right policy for a worst-case scenario, whether no packet should pass unexamined, or your traffic must flow-no matter what. Integrated hardware bypass enables you to extend this policy to total system and power failures.
As part of the most diverse line of IPS technologies available, Cisco IPS 4200 Series Sensors can be deployed in a variety of IPv4 and IPv6 network environments. The wide range of performance and interface configurations in the IPS 4200 Series enable you to achieve effective intrusion prevention with unparalleled flexibility throughout the edge, campus, and data center.
• Cisco IPS 4200 Series Sensors can be deployed in an inline IPS configuration, a promiscuous IDS configuration, or both inline and promiscuous simultaneously.However a word of caution in regars to inline deployments .A fair amount of traffic monitoring and cisco ips signatures tunnning is required before going live in order to acsertain no disruption to the normal traffic operations.
• Your critical assets on IPv4 and IPv6 networks can be protected with a single Cisco IPS 4200 Series Sensor for maximum deployment flexibility and lower total cost of ownership. Cisco IPS 4200 Series Sensors provide investment protection for customers planning or considering migration to IPv6 or hybrid IPv4 and IPv6 networks.
• Appliances in the Cisco IPS 4200 Series are available in a variety of multiple-interface configurations, featuring copper and fiber Gigabit Ethernet, and 10 Gigabit Ethernet interfaces. You can also configure thousands of logical interfaces and implement intrusion prevention within your VLAN environment, giving you the design flexibility to address all of your deployment requirements, from simple to complex.
• Cisco IPS technologies also feature industry-leading virtualization capabilities. Virtual sensors enable the virtualization of both the configuration and the sensor state.
As shown in Figure 1, sensors can be placed on almost any enterprise network segment where security visibility is required to effectively stop worms and viruses.
Cisco IPS 4200 Series Sensors are designed to meet the rigors of a broad range of applications and network use. In today's enterprises, applications are using the Internet as never before. Voice over IP, e-commerce, streaming video, and Web 2.0 enable higher productivity and employee collaboration. These networked applications pose different and varying demands on resources such as connection rates, concurrent connections, flow length, transaction size, etc. From a performance perspective, there is a spectrum of application types ranging from media-rich environments that feature converged content to highly transactional environments populated by rapid-fire, lightweight connections.
Cisco IPS technology evaluates a diverse suite of metrics in both "media-rich" and "transactional" environments, enabling you to anticipate true IPS performance based on the unique characteristics of your real-world environment.
Media-rich environments are characterized by content. Content seen on most popular websites falls on the media-rich end of the spectrum, as do video content and file transfers. If your environment is driven by access to large amounts of data and converged, immersive experiences, your environment is more media-rich.
Transactional environments are characterized by connections. Many types of e-commerce environments fall on this end of the spectrum, as can instant messaging and voice. If your environment is driven by connection-intensive applications and small transaction sizes, your environment is more transactional.
