Chapter 19 Configuring the ASA 5585-X IPS SSP

Configuration Sequence for the ASA 5585-X IPS SSP

•The ASA 5585-X IPS SSP has four types of ports (console, management, GigabitEthernet, and 10GE). The console and management ports (on the right front panel of the ASA 5585-X IPS SSP) are configured and controlled by IPS software. The GigabitEthernet and 10GE ports (on the left front panel of the ASA 5585-X IPS SSP) are configured and controlled by ASA software rather than IPS software. However, when you reset or shut down the ASA 5585-X IPS SSP, the GigabitEthernet and 10GE ports will also link down. You should reset or shut down the ASA 5585-X IPS SSP during scheduled maintenance windows to minimize the effect of the link down on these ports.

TCP Reset Differences Between IPS Appliances and ASA IPS Modules

The IPS appliance sends TCP reset packets to both the attacker and victim when reset-tcp-connection is selected. The IPS appliance sends a TCP reset packet only to the victim under the following circumstances:

•When a deny-packet-inline or deny-connection-inline is selected

•When TCP-based signatures and reset-tcp-connection have NOT been selected

In the case of the ASA IPS modules, the TCP reset request is sent to the ASA, and then the ASA sends the TCP reset packets. The ASA sends TCP reset packets to both the attacker and victim when the reset-tcp-connection is selected. When deny-packet-inline or deny-connection-inline is selected, the ASA sends the TCP reset packet to either the attacker or victim depending on the configuration of the signature. Signatures configured to swap the attacker and victim when reporting the alert can cause the ASA to send the TCP reset packet to the attacker.

Configuration Sequence for the ASA 5585-X IPS SSP

Perform the following tasks to configure the ASA 5585-X IPS SSP:

1.Obtain and install the current IPS software if your software is not up to date.

2.Obtain and install the license key.

3.Log (session) in to the ASA 5585-X IPS SSP.

4.Run the setup command to initialize the ASA 5585-X IPS SSP.

5.Verify initialization for the ASA 5585-X IPS SSP.

6.Configure the adaptive security appliance to send IPS traffic to the ASA 5585-X IPS SSP.

7.Perform other initial tasks, such as adding users, trusted hosts, and so forth.

8.Configure intrusion prevention.

9.Configure global correlation.

10.Perform miscellaneous tasks to keep your ASA 5585-X IPS SSP running smoothly.

11.Upgrade the IPS software with new signature updates and service packs as they become available.

12.Reimage the ASA 5585-X IPS SSP when needed.

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.
