Chapter 11 Configuring External Product Interfaces

Adding External Product Interfaces and Posture ACLs

The following options apply:

•enabled {yes no}—Enables/disables the receipt of information from the CSA MC.

•host-posture-settings—Specifies how host postures received from the CSA MC are handled:

–allow-unreachable-postures {yes no}—Allows postures for hosts that are not reachable by the CSA MC.

A host is not reachable if the CSA MC cannot establish a connection with the host on any IP addresses in the posture of the host. This option is useful in filtering the postures whose IP addresses may not be visible to the IPS or may be duplicated across the network. This filter is most applicable in network topologies where hosts that are not reachable by the CSA MC are also not reachable by the IPS, for example if the IPS and the CSA MC are on the same network segment.

–enabled {yes no}—Enables/disables receipt of host postures from the CSA MC.

–posture-acls {edit insert move} name1 {begin end inactive before after}—Specifies the list of permitted or denied posture addresses. This command provides a mechanism for filtering postures that have IP addresses that may not be visible to the IPS or may be duplicated across the network.

–action {permit deny}—Specifies the permit or deny postures that match the specified network address.

–network-addressaddress—Specifies the network address, in the form x.x.x.x/nn, for postures to be permitted or denied.

•password—Specifies the password used to log in to the CSA MC.

•port —Specifies the TCP port to connect to on the CSA MC. The valid range is 1 to 65535. The default is 443.

•username —Specifies the username used to log in to the CSA MC.

•watchlist-address-settings—Specifies how watch listed addresses received from the CSA MC are handled:

–enabled {yes no}—Enables/disables receipt of watch list addresses from the CSA MC.

–manual-rr-increase—Specifies the number added to an event RR because the attacker has been manually watch-listed by the CSA MC. The valid range is 0 to 35. The default is 25.

–packet-rr-increase—Specifies the number added to an event risk rating because the attacker has been watch listed by the CSA MC because of a sessionless packet-based policy violation. The valid range is 0 to 35. The default is 10.

–session-rr-increase—Specifies the number added to an event risk rating because the attacker has been watch-listed by the CSA MC because of a session-based policy violation. The valid range is 0 to 35. The default is 25.

Note Make sure you add the external product as a trusted host so the sensor can communicate with it.

Adding External Product Interfaces

To add external product interfaces, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter external product interfaces submode.

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.
