Configuring Anomaly Detection Operational Settings

Use the worm-timeoutcommand in service anomaly detection submode to set the worm detection timeout. After this timeout, the scanner threshold returns to the configured value. Use the ignore command in service anomaly detection submode to configure source and destination IP addresses that you want the sensor to ignore when anomaly detection is gathering information for a KB. Anomaly detection does not track these source and destination IP addresses and the KB thresholds are not affected by these IP addresses.

The following options apply:

•worm-timeout—Specifies the amount of time in seconds for the worm termination timeout. The range is 120 to 10,000,000 seconds. The default is 600 seconds.

•ignore—Specifies the IP addresses that should be ignored while anomaly detection is processing:

–enabled {true false}—Enables/disables the list of ignored IP addresses. The default is enabled.

–source-ip-address-range—Specifies the source IP addresses that you want anomaly detection to ignore during processing.

–dest-ip-address-range—Specifies the destination IP addresses that you want anomaly detection to ignore during processing.

Note IP addresses are in the form of <A.B.C.D>-<A.B.C.D>[,<A.B.C.D>-<A.B.C.D>].

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.
