Cisco TSHOOT 1.0: Maintaining and Troubleshooting Network Security Solutions

This course is included in our On-demand training solution.


Any network that is deployed needs to be secured. The level of security that you need and the features that will be deployed are dependent on the organization and its security policies. Implementation of infrastructure security has a definite impact on network maintenance and troubleshooting processes as the security features add an extra layer of complexity to the network and introduce a plethora of new potential problem causes. Security features tend to focus on restricting the flow of traffic, and because of that, engineers should be aware of the features implemented at each point in the network and how they affect network connectivity.
Another important aspect of troubleshooting in a secured network is that the actions that an engineer is allowed to perform might be limited by the security policy. As part of the change control procedures, each change needs to be evaluated for compliance with the security policy. Even temporary changes made as part of the diagnosis during troubleshooting processes need to be carefully evaluated against the policies of the organization.
This course reviews security features that are commonly deployed in routed and switched network infrastructures and focuses on the diagnosis and resolution of network connectivity problems in a secured infrastructure.
