Chapter 1 Introducing the Sensor

How the Sensor Functions

–For Gigabit copper interfaces (1000-TX on the IPS 4240, IPS 4255, IPS 4260, IPS 4270-20,, IPS 4345, IPS 4360, IPS 4510, and IPS 4520), valid speed settings are 10 Mbps, 100 Mbps, 1000 Mbps, and auto. Valid duplex settings are full, half, and auto.

–For Gigabit (copper or fiber) interfaces, if the speed is configured for 1000 Mbps, the only valid duplex setting is auto.

–The command and control interface cannot also serve as a sensing interface.

•Inline Interface Pairs

–Inline interface pairs can contain any combination of sensing interfaces regardless of the physical interface type (copper versus fiber), speed, or duplex settings of the interface. However, pairing interfaces of different media type, speeds, and duplex settings may not be fully tested or supported.

–The command and control interface cannot be a member of an inline interface pair.

–You cannot pair a physical interface with itself in an inline interface pair.

–A physical interface can be a member of only one inline interface pair.

–You can only configure bypass mode and create inline interface pairs on sensor platforms that support inline mode.

–A physical interface cannot be a member of an inline interface pair unless the subinterface mode of the physical interface is none.

Note You can configure the ASA IPS modules (ASA 5500 AIP SSM, ASA 5500-X IPS SSP, and ASA 5585-X IPS SSP) to operate inline even though they have only one sensing interface.

•Inline VLAN Pairs

–You cannot pair a VLAN with itself.

–You cannot use the default VLAN as one of the paired VLANs in an inline VLAN pair.

–For a given sensing interface, a VLAN can be a member of only one inline VLAN pair. However, a given VLAN can be a member of an inline VLAN pair on more than one sensing interface.

–The order in which you specify the VLANs in an inline VLAN pair is not significant.

–A sensing interface in Inline VLAN Pair mode can have from 1 to 255 inline VLAN pairs.

Note The ASA IPS modules (ASA 5500 AIP SSM ,ASA 5500-X IPS SSP, and ASA 5585-X IPS SSP) do not support inline VLAN pairs.

•Alternate TCP Reset Interface

–You can only assign the alternate TCP reset interface to a sensing interface. You cannot configure the command and control interface as an alternate TCP reset interface. The alternate TCP reset interface option is set to none as the default and is protected for all interfaces except the sensing interfaces.

–You can assign the same physical interface as an alternate TCP reset interface for multiple sensing interfaces.

–A physical interface can serve as both a sensing interface and an alternate TCP reset interface.

IPS4520K9 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.
