Time Sources and the Sensor

This section explains the importance of having a reliable time source for the sensors and how to correct the time if there is an error. It contains the following topics:

•The Sensor and Time Sources, page 1-23

•Synchronizing IPS Module System Clocks with the Parent Device System Clock, page 1-23

•Verifying the Sensor is Synchronized with the NTP Server, page 1-24

•Correcting the Time on the Sensor, page 1-24

The Sensor and Time Sources

Note We recommend that you use an NTP server to regulate time on your sensor. You can use authenticated or unauthenticated NTP. For authenticated NTP, you must obtain the NTP server IP address, NTP server key ID, and the key value from the NTP server. You can set up NTP during initialization or you can configure NTP through the CLI, IDM, IME, or ASDM.

The sensor requires a reliable time source. All events (alerts) must have the correct UTC and local time stamp, otherwise, you cannot correctly analyze the logs after an attack. When you initialize the sensor, you set up the time zones and summertime settings. This section provides a summary of the various ways to set the time on sensors.

The IPS Standalone Appliances

•Use the clock set command to set the time. This is the default.

•Configure the appliance to get its time from an NTP time synchronization source.

Note The currently supported Cisco IPS appliances are the IPS 4240, IPS 4255, and IPS 4260 [IPS 7.0(x) and later and IPS 7.1(5) and later], IPS 4270-20 [IPS 7.1(3) and later], IPS 4345 and IPS 4360 [IPS 7.1(3) and later], and IPS 4510 and IPS 4520 [IPS 7.1(4) and later].

The ASA IPS Modules

•The ASA 5500-X IPS SSP and ASA 5585-X IPS SSP automatically synchronize their clocks with the clock in the adaptive security appliance in which they are installed. This is the default.

•Configure them to get their time from an NTP time synchronization source, such as a Cisco router other than the parent router.

Synchronizing IPS Module System Clocks with the Parent Device System Clock

The ASA IPS modules (ASA 5500 AIP SSM, ASA 5500-X IPS SSP, and ASA 5585-X IPS SSP) synchronize their clocks to the parent chassis clock (switch, router, or adaptive security appliance) each time the IPS boots up and any time the parent chassis clock is set. The IPS clock and parent chassis clock tend to drift apart over time. The difference can be as much as several seconds per day. To avoid this problem, make sure that both the IPS clock and the parent clock are synchronized to an external NTP server. If only the IPS clock or only the parent chassis clock is synchronized to an NTP server, the time drift occurs.

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.
