Configuring Health Status Information

Configure the health statistics for the sensor in service health monitor submode. Use the show health command to see the results. The health status categories are rated by red and green with red being critical.

The following options apply:

•application-failure-policy {enable disable} {true false} status {green yellow red}—Lets you choose to have an application failure applied to the overall sensor health rating.

•bypass-policy {enable disable} {true false} status {green yellow red}—Lets you choose to know if bypass mode is active and have that apply to the overall sensor health rating.

Note The ASA 5500-X IPS SSP and the ASA 5585-X IPS SSP do not support bypass mode. The adaptive security appliance will either fail open, fail close, or fail over depending on the configuration of the adaptive security appliance and the type of activity being done on the IPS.

•enable-monitoring{true false}—Lets you choose to monitor sensor health and security.

•event-retrieval-policy {enable disable} {true false} red-threshold yellow-threshold seconds—Lets you set a threshold for when the last event was retrieved and have that apply to the overall sensor health rating. The health status is degraded to red or yellow when that threshold is met. The range for the threshold is 0 to 4294967295 seconds.

Note The event retrieval metric keeps track of when the last event was retrieved by an external monitoring application such as the IME. Disable event retrieval policy if you are not doing external event monitoring.

•global-correlation-policy {enable disable} {true false}—Lets you apply this metric to the overall sensor health rating.

•heartbeat-events {enable disable} seconds—Lets you enable heartbeat events to be emitted at the specified interval in seconds and have that apply to the overall sensor health rating. The range for the interval is 15 to 86400 seconds.

•inspection-load-policy {enable disable} {true false} red-threshold yellow-threshold seconds—Lets you set the threshold for inspection load. The health status is degraded to red or yellow when that threshold is met. The range is 0 to 100.

•interface-down-policy {enable disable} {true false} status {green yellow red}—Lets you choose to know if one or more enabled interfaces are down and have that apply to the overall sensor health rating.

•license-expiration-policy {enable disable} {true false} red-threshold yellow-threshold—Lets you set a threshold for when the license expires and whether this metric is applied to the overall sensor health rating. The range for the threshold is 0 to 4294967295 seconds.

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.
