Sensor Events

There are five types of events:

•evAlert—Intrusion detection alerts

•evError—Application errors

•evStatus—Status changes, such as an IP log being created

•evLogTransaction—Record of control transactions processed by each sensor application

•evShunRqst—Block requests

Events remain in the Event Store until they are overwritten by newer events.

Understanding the show events Command

The show events command is useful for troubleshooting event capture issues in which you are not seeing events in Event Viewer or Security Monitor. You can use the show events command to determine which events are being generated on the sensor to make sure events are being generated and that the fault lies with the monitoring side.

You can clear all events from Event Store by using the clear events command.

Here are the parameters for the show events command:

sensor# show events

<cr>

 

alert

Display local system alerts.

error

Display error events.

hh:mm[:ss]

Display start time.

log

Display log events.

nac

Display NAC shun events.

past

Display events starting in the past specified time.

status

Display status events.

Output modifiers.

Displaying Events

Note The Event Store has a fixed size of 30 MB for all platforms.

Note Events are displayed as a live feed. To cancel the request, press Ctrl-C.

Use the show events [{alert [informational] [low] [medium] [high] [include-traitstraits]

[exclude-traits traits] [min-threat-rating min-rr][max-threat-rating max-rr] error [warning] [error] [fatal] NAC status}] [hh:mm:ss [month day [year]] past hh:mm:ss] command to display events from Event Store. Events are displayed beginning at the start time. If you do not specify a start time, events are displayed beginning at the current time. If you do not specify an event type, all events are displayed.

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.
