What is required for the licensing of Tenable.SC?

The licensing for Tenable Security Center (SC) requires a Tenable Security Center license activation code because this code is essential to verify that the installation is legitimate and authorized to function. The activation code is tied to the specific instance of the software and the licensing terms agreed upon with Tenable. It ensures that users have access to the features and updates designated for their purchased license level, enabling proper compliance with licensing regulations.

Other choices do not fulfill the licensing requirement in the same direct manner. Network configuration settings and a valid IP address may be necessary for the operation and connectivity of the software but do not pertain to the licensing process itself. Similarly, a user account for Nessus is essential for vulnerability scanning but does not relate to the activation or licensing of the Tenable Security Center software. Therefore, the license activation code is specifically required to legally utilize the functionalities this software offers.
