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.
