Chapter 17 Administrative Tasks for the Sensor

Resetting the Appliance

To diagnose basic network connectivity, follow these steps:

Step 1 Log in to the CLI.

Step 2 Ping the address you are interested in. The count is the number of echo requests to send. If you do not specify a number, 4 requests are sent. The range is 1 to 10,000.

sensor# ping ip_address count

The following example shows a successful ping:

sensor# ping 192.0.2.1 6

PING 192.0.2.1 (192.0.2.1): 56 data bytes

64bytes from 192.0.2.1: icmp_seq=0 ttl=61 time=0.3 ms

64bytes from 192.0.2.1: icmp_seq=1 ttl=61 time=0.1 ms

64bytes from 192.0.2.1: icmp_seq=2 ttl=61 time=0.1 ms

64bytes from 192.0.2.1: icmp_seq=3 ttl=61 time=0.2 ms

64bytes from 192.0.2.1: icmp_seq=4 ttl=61 time=0.2 ms

64bytes from 192.0.2.1: icmp_seq=5 ttl=61 time=0.2 ms

--- 192.0.2.1 ping statistics ---

6 packets transmitted, 6 packets received, 0% packet loss round-trip min/avg/max = 0.1/0.1/0.3 ms

The following example shows an unsuccessful ping:

sensor# ping 172.16.0.0 3

PING 172.16.0.0 (172.16.0.0): 56 data bytes

--- 172.16.0.0 ping statistics ---

3 packets transmitted, 0 packets received, 100% packet loss sensor#

Resetting the Appliance

Use the reset [powerdown] command to shut down the applications running on the appliance and to reboot the appliance. You can include the powerdown option to power off the appliance, if possible, or to have the appliance left in a state where the power can be turned off.

Shutdown (stopping the applications) begins immediately after you execute the command. Shutdown can take a while, and you can still access CLI commands while it is taking place, but the session is terminated without warning.

To reset the appliance, follow these steps:

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

Step 2 To stop all applications and reboot the appliance, follow these Steps 2 and 3. Otherwise, to power down the appliance, go to Steps 4 and 5.

sensor# reset

Warning: Executing this command will stop all applications and reboot the node.

Continue with reset? []:

Step 3 Enter yes to continue the reset.

sensor# yes Request Succeeded.

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.
