Chapter 8 Configuring Event Action Rules

Configuring Event Action Filters

Configuring Event Action Filters

To configure event action filters, follow these steps:

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

Step 2 Enter event action rules submode.

sensor# configure terminal

sensor(config)# service event-action-rules rules1

sensor(config-eve)#

Step 3 Create the filter name. Use name1, name2, and so forth to name your event action filters. Use the begin end inactive before after keywords to specify where you want to insert the filter.

sensor(config-eve)#filters insert name1 begin

Step 4 Specify the values for this filter:

a.Specify the signature ID range. The default is 900 to 65535.

sensor(config-eve-fil)#signature-id-range 1000-1005

b.Specify the subsignature ID range. The default is 0 to 255.

sensor(config-eve-fil)#subsignature-id-range 1-5

c.Specify the attacker address range for IPv4 or IPv6.

sensor(config-eve-fil)#attacker-address-range 192.0.2.3-192.0.2.26 sensor(config-eve-fil)#ipv6-attacker-address-range

2001:0db8:3c4d:0015:0000:0000:abcd:ef12

d.Specify the victim address range for IPv4 or IPv6.

sensor(config-eve-fil)#victim-address-range 192.56.10.1-192.56.10.255 sensor(config-eve-fil)#ipv6-victim-address-range ::0-FFFF:FFFF:FFFF:FFFF:FFFF:

FFFF:FFFF:FFFF

e.Specify the victim port range. The default is 0 to 65535.

sensor(config-eve-fil)# victim-port-range0-434

f.Specify the OS relevance. The default is 0 to 100.

sensor(config-eve-fil)# os-relevance relevant

g.Specify the risk rating range.The default is 0 to 100.

sensor(config-eve-fil)# risk-rating-range85-100

h.Specify the actions to remove.

sensor(config-eve-fil)#actions-to-remove reset-tcp-connection

i.If you are filtering a deny action, set the percentage of deny actions you want. The default is 100.

sensor(config-eve-fil)#deny-attacker-percentage 90

j.Specify the status of the filter to either disabled or enabled. The default is enabled.

sensor(config-eve-fil)#filter-item-status {enabled disabled}

k.Specify the stop on match parameter. True tells the sensor to stop processing filters if this item matches. False tells the sensor to continue processing filters even if this item matches.

sensor(config-eve-fil)#stop-on-match {true false}

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.
