Configurations and policies for a system can come from a variety of sources and take a variety of formats. Which concept pertains to the application of a set of configurations and policies that is applied to all systems or a class of systems? 

Answer options:

A. Hardening
B. Leveling
C. Baselines
D. Standards

C

Baselines are a set of configurations and policies applied to all new systems or services, and they serve as the basis for deploying any other services on top of them. Although standards often form the basis for baselines, the term is applicable in this case. Hardening is the process of securing a system, often through the application of baselines. Leveling is an extraneous but similar term to baselining.
