The best way to mitigate the high cost of retrieving electronic evidence associated with potential litigation is to implement policies and procedures for data retention and destruction. Data retention and destruction policies and procedures define the criteria, methods, and schedules for retaining and disposing of electronic data. They help to ensure that the electronic data is stored, managed, and deleted in a consistent, secure, and compliant manner. They also help to reduce the volume, complexity, and cost of retrieving electronic evidence, as they limit the scope, duration, and frequency of the data preservation and discovery process. The other options are not as effective as data retention and destruction policies and procedures, as they are related to the collection, analysis, or classification of electronic data, not the retention or destruction of electronic data. References = Risk and Information Systems Control Study Manual, Chapter 3: IT Risk Response, Section 3.3: IT Risk Response Implementation, page 145.
