Chapter 19 Configuring the ASA 5585-X IPS SSP

ASA 5585-X IPS SSP and Jumbo Packets

The SensorApp Fails

The following occurs when the SensorApp fails:

•If the adaptive security appliance is configured for failover, then the adaptive security appliance fails over.

•If the adaptive security appliance is not configured for failover or failover is not possible:

–If set to fail-open, the adaptive security appliance passes traffic without sending it to the ASA IPS module.

–If set to fail-close, the adaptive security appliance stops passing traffic until the ASA IPS module is restarted.

The SensorApp is Reconfigured

The following occurs when the SensorApp is reconfigured:

•If set to fail-open, the adaptive security appliance passes traffic without sending it to the ASA IPS module.

•If set to fail-close, the adaptive security appliance stops passing traffic until the ASA IPS module is restarted.

Note The adaptive security appliance does not failover unless the reconfiguration is not completed.

ASA 5585-X IPS SSP and Jumbo Packets

The jumbo packet count in the show interface command output from the lines Total Jumbo Packets Received and Total Jumbo Packets Transmitted for ASA IPS modules may be larger than expected due to some packets that were almost jumbo size on the wire being counted as jumbo size by the IPS.

This miscount is a result of header bytes added to the packet by the ASA before the packet is transmitted to the IPS. For IPv4, 58 bytes of header data are added. For IPv6, 78 bytes of header data are added. The ASA removes the added IPS header before the packet leaves the ASA.

Reloading, Shutting Down, Resetting, and Recovering the ASA 5585-XIPS SSP

Note You can enter the hw-modulecommands from privileged EXEC mode or from global configuration mode. You can enter the commands in single routed mode and single transparent mode. For adaptive security appliances operating in multi-mode (routed or transparent multi-mode) you can only execute the hw-modulecommands from the system context (not from administrator or user contexts).

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.
