Chapter 21 Upgrading, Downgrading, and Installing System Images

Configuring Automatic Upgrades

You specify the following information to schedule automatic upgrades:

•Server IP address

•Path of the directory on the file server where the sensor checks for upgrade files

•File copy protocol (SCP or FTP)

•Username and password

•Upgrade schedule

You must download the software upgrade from Cisco.com and copy it to the upgrade directory before the sensor can poll for automatic upgrades.

Use the auto-upgrade-option enabled command in the service host submode to configure automatic upgrades.

The following options apply:

•cisco-server {disabled enabled}—Enables automatic signature and engine updates from Cisco.com.

•cisco-urlcisco_url—Specifies the Cisco server locator service. You do not need to change this unless the www.cisco.com IP address changes.

•default— Sets the value back to the system default setting.

•directory directory— Specifies the directory where upgrade files are located on the file server. A leading ‘/’ indicates an absolute path.

•file-copy-protocol {ftp scp}— Specifies the file copy protocol used to download files from the file server.

Note If you use SCP, you must use the ssh host-keycommand to add the server to the SSH known hosts list so the sensor can communicate with it through SSH.

•ip-addressip_address—Specifies the IP address of the file server.

•password password—Specifies the user password for Cisco server authentication.

•schedule-option—Specifies the schedules for when Cisco server automatic upgrades occur. Calendar scheduling starts upgrades at specific times on specific days. Periodic scheduling starts upgrades at specific periodic intervals.

–calendar-schedule—Configures the days of the week and times of day that automatic upgrades will be performed.

–days-of-week—Specifies the days of the week on which auto-upgrades will be performed. You can select multiple days: sunday through saturday are the valid values.

–no—Removes an entry or selection setting.

–times-of-day—Specifies the times of day at which auto-upgrades will begin. You can select multiple times. The valid value is hh:mm[:ss].

–periodic-schedule—Specifies the time that the first automatic upgrade should occur, and how long to wait between automatic upgrades.

–interval—Specifies the number of hours to wait between automatic upgrades. Valid values are 1 to 8760. The default value is 24.

–start-time—Specifies the time of day to start the first automatic upgrade. The valid value is hh:mm[:ss]. The default is 00:00:00.

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.
