Chapter 5 Configuring Virtual Sensors

Adding, Editing, and Deleting Virtual Sensors

	Step 6	Assign an event action rules policy to this virtual sensor.
		sensor(config-ana-vir-ano)# exit
		sensor(config-ana-vir)#event-action-rules rules1
	Step 7	Assign a signature definition policy to this virtual sensor.
		sensor(config-ana-vir)#signature-definition sig1
	Step 8	Enable HTTP advanced decoding.
		sensor(config-ana-vir)#http-advanced-decoding true

Caution		Enabling HTTP advanced decoding severely impacts system performance.

	Step 9	Assign the inline TCP session tracking mode. The default is virtual sensor mode, which is almost always
		the best option to choose.
		sensor(config-ana-vir)#inline-TCP-session-tracking-mode virtual-sensor
	Step 10	Assign the inline TCP evasion protection mode. The default is strict mode, which is almost always the
		best option to choose.
		sensor(config-ana-vir)#inline-TCP-evasion-protection-mode strict
	Step 11	Enable HTTP advanced decoding.
		sensor(config-ana-vir)#http-advanced-decoding true
	Step 12	Display the list of available interfaces.
		sensor(config-ana-vir)# physical-interface ?
		GigabitEthernet0/0	GigabitEthernet0/0 physical interface.
		GigabitEthernet0/1	GigabitEthernet0/1 physical interface.
		GigabitEthernet2/0	GigabitEthernet0/2 physical interface.
		GigabitEthernet2/1	GigabitEthernet0/3 physical interface.
		sensor(config-ana-vir)# physical-interface
		sensor(config-ana-vir)# logical-interface ?
		<none available>
	Step 13	Assign the promiscuous mode interfaces you want to add to this virtual sensor. Repeat this step for all
		the promiscuous interfaces that you want to assign to this virtual sensor.
		sensor(config-ana-vir)#physical-interface GigabitEthernet0/3
	Step 14	Assign the inline interface pairs you want to add to this virtual sensor. You must have already paired the
		interfaces.
		sensor(config-ana-vir)#logical-interfaceinline_interface_pair_name
	Step 15	Assign the subinterfaces of the inline VLAN pairs or groups you want to add to this virtual sensor. You
		must have already subdivided any interfaces into VLAN pairs or groups.
		sensor(config-ana-vir)#physical-interface GigabitEthernet2/0 subinterface-number
		subinterface_number
	Step 16	Verify the virtual sensor settings.
		sensor(config-ana-vir)# show settings

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.
