Configuring Global Correlation Inspection and Reputation Filtering

Caution For automatic and global correlation updates to function, you must have either a DNS server or an HTTP proxy server configured at all times.

The following options apply:

global-correlation-inspection {on off}—Turns global correlation inspection on or off. When turned on, the sensor uses updates from the SensorBase network to adjust the risk rating. The default is on.

global-correlation-inspection-influence {permissive standard aggressive}—Lets you choose the level of global correlation inspection. The default is standard.

permissive—Global correlation data has little influence in the decision to deny traffic.

standard—Global correlation moderately influences the decision to deny traffic.

aggressive—Global correlation data heavily influences the decision to deny traffic.

reputation-filtering {on off}—Turns reputation filtering on or off. When turned on, the sensor denies access to malicious hosts that are listed in the global correlation database. The default is on.

test-global-correlation {on off}—Enables reporting of deny actions that are affected by global correlation. Allows you to test the global correlation features without actually denying any hosts. The default is off.

Configuring Global Correlation

To configure global correlation features, follow these steps:

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

Step 2 Enter global correlation submode.

sensor# configure terminal

sensor(config)# service global-correlation

sensor(config-glo)#

Step 3 Turn on global correlation inspection.

sensor(config-glo)#global-correlation-inspection on

sensor(config-glo)#

Step 4 Specify the level of global correlation inspection.

sensor(config-glo)#global-correlation-inspection-influence aggressive

sensor(config-glo)#

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.
