Appendix D Upgrading, Downgrading, and Installing System Images

Upgrades, Downgrades, and System Images

•You cannot use the downgrade command to revert to a previous major or minor version, for example, from Cisco IPS 7.1 to 7.0. You can only use the downgrade command to downgrade from the latest signature update or signature engine update. To revert to 7.0, you must reimage the sensor.

•All user configuration settings are lost when you install the system image. Before trying to recover the sensor by installing the system image, try to recover by using the recover application-partitioncommand or by selecting the recovery partition during sensor bootup.

Upgrades, Downgrades, and System Images

Caution You cannot use the downgrade command to revert to a previous major or minor version, for example, from Cisco IPS 7.1 to 7.0. You can only use the downgrade command to downgrade from the latest signature update or signature engine update. To revert to 7.0, you must reimage the sensor.

You can upgrade and downgrade the software on the sensor. Upgrading applies a service pack, signature update, signature engine update, minor version, major version, or recovery partition file. Downgrading removes the last applied service pack or signature update from the sensor.

You can recover the application partition image on your sensor if it becomes unusable. Using the recover command lets you retain your host settings while other settings revert to the factory defaults.

To install a new system image on the sensor, use ROMMON, the bootloader file, or the maintenance partition depending on which platform you have. When you install a new system image on your sensor, all accounts are removed and the default cisco account is reset to use the default password cisco. After installing the system image, you must initialize the sensor again.

After you reimage and initialize your sensor, upgrade your sensor with the most recent service pack, signature update, signature engine update, minor update, major update, and recovery partition files.

For More Information

•For the procedure for initializing the sensor, see Appendix B, “Initializing the Sensor.”

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.
