ASA 5500-X IPS SSP and Memory Usage

Chapter 17 Administrative Tasks for the Sensor

Configuring Health Status Information

•memory-usage-policy {enable disable} {true false} red-threshold yellow-threshold—Lets you set a threshold percentage for memory usage and whether this metric is applied to the overall sensor health rating. The range is 0 to 100. The default for red is 91% and the default for yellow is 80%.

•missed-packet-policy {enable disable} {true false} red-threshold yellow-threshold—Lets you set a threshold percentage for missed packets and whether this metric is applied to the overall sensor health rating.

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

•persist-security-status—Lets you set the number of minutes that a lower security persists following the occurrence of the latest event to lower the security status.

•signature-update-policy {enable disable} {true false} red-threshold yellow-threshold—Lets you set a threshold for the number of days elapsed since the last signature update and whether this metric is applied to the overall sensor health rating. The range for the threshold is 0 to 4294967295 seconds

For the ASA 5500-X IPS SSP, the memory usage is 93%. The default health thresholds for the sensor are 80% for yellow and 91% for red, so the sensor health will be shown as red on these platforms even for normal operating conditions. You can tune the threshold percentage for memory usage so that it reads more accurately for these platforms by configuring the memory-usage-policyoption in the sensor health metrics.

Note Make sure you have the memory-usage-policyoption in the sensor health metrics enabled.

Table 17-2lists the yellow-threshold and red-threshold health values.

Configuring Health Statistics

To configure the health statistics for the sensor, follow these steps:

Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter service health monitor submode.

sensor# configure terminal

sensor(config)# service health-monitor

sensor(config-hea)#

Step 3 Enable the metrics for application failure status.

sensor(config-hea)#application-failure-policy

sensor(config-hea-app)# enable true

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.
