The FIRST step in data classification is to:

A.
establish ownership.

B.
perform a criticality analysis.

C.
define access rules.

D.
create a data dictionary.

Explanation:
Data classification is necessary to define access rules based on a need-to-do and need-to-know basis. The
data owner is responsible for defining the access rules; therefore, establishing ownership is the first step in data
classification. The other choices are incorrect. A criticality analysis is required for protection of data, which
takes input from data classification. Access definition is complete after data classification and input for a data
dictionary is prepared from the data classification process.
