Chapter 14 Configuring Attack Response Controller for Blocking and Rate Limiting

Disabling Blocking

Step 4 Disable blocking event and error logging.

sensor(config-net-gen)#log-all-block-events-and-errors false

Step 5 Verify that logging is disabled.

sensor(config-net-gen)# show settings general

-----------------------------------------------

log-all-block-events-and-errors: false default: true

enable-nvram-write: false default: false

enable-acl-logging: false default: false

allow-sensor-block: false <defaulted>

block-enable: true <defaulted>

block-max-entries: 250 <defaulted>

max-interfaces: 250 <defaulted>

master-blocking-sensors (min: 0, max: 100, current: 0)

-----------------------------------------------

Step 6 Enable blocking event and error logging.

sensor(config-net-gen)#log-all-block-events-and-errors true

Step 7 Verify that logging is enabled.

sensor(config-net-gen)# show settings general

-----------------------------------------------

log-all-block-events-and-errors: true default: true

enable-nvram-write: false default: false

enable-acl-logging: false default: false

allow-sensor-block: false <defaulted>

block-enable: true <defaulted>

block-max-entries: 250 <defaulted>

max-interfaces: 250 <defaulted>

master-blocking-sensors (min: 0, max: 100, current: 0)

-----------------------------------------------

Step 8 Exit network access mode.

sensor(config-net-gen)# exit sensor(config-net)# exit

Apply Changes:?[yes]:

Step 9 Press Enter to apply the changes or type no to discard them.

Configuring the Maximum Number of Blocking Interfaces

Use the max-interfacescommand to configure the maximum number of interfaces for performing blocks. For example, a PIX Firewall counts as one interface. A router with one interface counts as one, but a router with two interfaces counts as two. At most you can configure 250 blocking interfaces on a router, switch, or firewall. You can configure up to 250 Catalyst 6K switches, 250 routers, and 250 firewalls.

The max-interfacescommand configures the limit of the sum total of all interfaces and devices. In addition to configuring the limit on the sum total of interfaces and devices, there is a fixed limit on the number of blocking interfaces you can configure per device. Use the show settings command in network access mode to view the specific maximum limits per device.

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.
