Chapter 8 Configuring Event Action Rules

Working With Event Action Rules Policies

3.Create overrides to add actions based on the risk rating value. Assign a risk rating to each event action type.

4.Create filters. Assign filters to subtract actions based on the ID, IP addresses, and risk rating of the signature.

5.Create OS mappings. OS mappings are used for the attack relevance rating in the calculation of the risk rating for an alert.

6.Configure the general settings. Specify whether you want to use the summarizer, the meta event generator, or configure denied attacker parameters.

Working With Event Action Rules Policies

Use the service event-action-rulesname command in service event action rules submode to create an event action rules policy. The values of this event action rules policy are the same as the default event action rules policy, rules0, until you edit them. Or you can use the copy event-action-rulessource_destination command in privileged EXEC mode to make a copy of an existing policy and then edit the values of the new policy as needed. Use the list event-action-rules-configurationscommand in privileged EXEC mode to list the event action rules policies. Use the no service event-action-rulesname command in global configuration mode to delete an event action rules policy. Use the default service event-action-rulesname command in global configuration mode to reset the event action rules policy to factory settings.

Working With Event Action Rules Policies

To create, copy, display, edit, and delete event action rules policies, follow these steps:

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

Step 2 Create an event action rules policy.

sensor# configure terminal

sensor(config)# service event-action-rules MyRules

sensor(config-eve)# exit

Apply Changes?[yes]: yes sensor(config)# exit sensor#

Step 3 Copy an existing event action rules policy to a new event action rules policy.

sensor# copy event-action-rules rules0 rules1

sensor#

Note You receive an error if the policy already exists or if there is not enough space available for the new policy.

Step 4 Accept the default event action rules policy values or edit the following parameters.

a.Add event action rules variables.

b.Configure event action rules overrides.

c.Configure event action rules filters.

d.Configure the event action rules general settings.

e.Configure the event action rules target value rating.

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.
