Which of the following is a method for creating a custom dashboard component?

Creating a custom dashboard component in Tenable Security Center can effectively enhance your ability to visualize and analyze data according to your specific needs. The method of copying an existing component template allows users to utilize the structure and format of current components while making the necessary adjustments or enhancements. This approach ensures that time is saved during the development process, as users can leverage established configurations and settings rather than starting from scratch.

Using predefined templates alone would not provide the flexibility needed for customization, as those templates come with fixed parameters. Purchasing additional software is also not necessary when you can modify existing components within the current system. Consulting the help desk may be useful for troubleshooting or questions about the platform, but it does not facilitate the actual creation of the custom components. Therefore, copying an existing component template stands out as the most effective and practical method for custom dashboard creation in Tenable Security Center.
