Generic CLI Commands

Chapter 1 Introducing the CLI Configuration Guide

To create a regular expression that recalls a previous pattern, you use parentheses to indicate memory of a specific pattern and a backslash (\) followed by a digit to reuse the remembered pattern. The digit specifies the occurrence of a parentheses in the regular expression pattern. If you have more than one remembered pattern in your regular expression, \1 indicates the first remembered pattern, and \2 indicates the second remembered pattern, and so on.

The following regular expression uses parentheses for recall:

•a(.)bc(.)\1\2 matches an a followed by any character, followed by bc followed by any character, followed by the first any character again, followed by the second any character again.

For example, the regular expression can match aZbcTZT. The software remembers that the first character is Z and the second character is T and then uses Z and T again later in the regular expression.

The following CLI commands are generic to the Cisco IPS.

•configure terminal—Enters global configuration mode.

Global configuration commands apply to features that affect the system as a whole rather than just one protocol or interface.

sensor# configure terminal

sensor(config)#

•service—Takes you to the following configuration submodes: analysis-engine, anomaly-detection, authentication, event-action-rules, external-product-interfaces, global-correlation, health-monitor, host, interface, logger, network-access, notification, signature-definition, ssh-known-hosts, trusted-certificates, and web-server.

Note The anomaly-detection, event-action-rules, and signature-definition submodes are multiple instance services. One predefined instance is allowed for each. For anomaly-detection, the predefined instance name is ad0. For event-action-rules, the predefined instance name is rules0. For signature-definition, the predefined instance name is sig0. You can create additional instances.

sensor# configure terminal

sensor(config)# service event-action-rules rules0

sensor(config-rul)#

•end—Exits configuration mode or any configuration submodes. It takes you back to the top-level EXEC menu.

sensor# configure terminal

sensor(config)# end sensor#

•exit—Exits any configuration mode or closes an active terminal session and terminates the EXEC mode. It takes you to the previous menu session.

sensor# configure terminal

sensor(config)# service event-action-rules rules0

sensor(config-rul)# exit

sensor(config)# exit sensor#

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.
