Appendix C Troubleshooting

Disaster Recovery

Note For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no password cisco command, but you cannot remove it. To use the no password cisco command, there must be another administrator account on the sensor. Removing the cisco account through the service account is not supported. If you remove the cisco account through the service account, the sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system image.

To create the service account, follow these steps:

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

Step 2 Enter configuration mode.

sensor# configure terminal

Step 3 Specify the parameters for the service account. The username follows the pattern ^[A-Za-z0-9()+:,_/-]+$, which means the username must start with a letter or number, and can include any letter A to Z (capital or small), any number 0 to 9, - and _, and can contain 1 to 64 characters.

sensor(config)# user username privilege service

Step 4 Specify a password when prompted. A valid password is 8 to 32 characters long. All characters except space are allowed. If a service account already exists for this sensor, the following error is displayed and no service account is created.

Error: Only one service account may exist

Step 5 Exit configuration mode.

sensor(config)# exit

sensor#

When you use the service account to log in to the CLI, you receive this warning.

************************ WARNING *******************************************************

UNAUTHORIZED ACCESS TO THIS NETWORK DEVICE IS PROHIBITED. This account is intended to be used for support and troubleshooting purposes only. Unauthorized modifications are not supported and will require this device to be reimaged to guarantee proper operation.

Disaster Recovery

Follow these recommendations so that you are ready in case of a disaster:

•If you are using the CLI, IDM, or IME for configuration, copy the current configuration from the sensor to an FTP or SCP server any time a change has been made.

•You should note the specific software version for that configuration. You can apply the copied configuration only to a sensor of the same version.

•You also need the list of user IDs that have been used on that sensor. The list of user IDs and passwords are not saved in the configuration.

When a disaster happens and you need to recover the sensor, try the following:

1.Reimage the sensor.

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.
