Explanation
Assessing potential information security risk to the organization is the first step that the information security manager should take when considering the feasibility of implementing a big data solution to analyze customer data, as it helps to identify and evaluate the threats, vulnerabilities, and impacts that may arise from the collection, processing, storage, and sharing of large volumes and varieties of customer data. Assessing risk also helps to determine the risk appetite and tolerance of the organization, and to prioritize the risk treatment options and security controls that are needed to protect the customer data and the big data solution.
