Securing data in the enterprise can pose a very challenging set of obstacles, further complicated by external requirements to do so. There are many methods and approaches to securing data at rest, in transit, and in use involving various types of technologies. The use of DLP, encryption, tokenization, data masking, and authorization are proven methods of securing data in the various states in which it may exist.

This chapter presented real-world scenarios and caveats for each technology that should be taken into consideration before any solution, or set of solutions, are selected and implemented. Topics covered thus far have been focused on all aspects of securing data through process, network security, system security, and lastly, data security. The next chapters will present securing data access through wireless networks; the human aspect of security, and developing supported enterprise security architecture.
