The first thing that should be done from a governance perspective to secure the information assets of a newly incorporated enterprise is to establish an inventory of information assets. An inventory of information assets is a document that lists and categorizes all the information assets that the organization owns, uses, or manages, such as data, documents, systems, applications, and devices. An inventory of information assets helps to identify and classify the information assets based on their value, sensitivity, and criticality, and to determine the appropriate level of protection and control for each asset. An inventory of information assets also helps to support the development and implementation of other information security activities, such as risk assessment, policy formulation, awareness training, and incident response. The other options are not the first thing that should be done, although they may be important steps or components of the information security governance. Defining information retention requirements and policies, providing information security awareness training, and establishing security management processes and procedures are all activities that can help to secure the information assets, but theyrequire the prior knowledge and understanding of the information assets. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.1.1, page 3-3.
