The ubiquitous need for data security / information assurance in test applications is no longer remotely controversial. But there exists significant confusion in the marketplace regarding the virtues and values of the various techniques and technologies. This paper discusses the standards and certifications used to protect data and explores the cost/benefit analysis of various approaches, including both traditional government-sponsored devices and commercial alternatives. There are many overlapping standards for encryption, both for data in transit and data at rest. While this paper mostly focusses on data at rest applications, there are many commonalities with data communications security problems. A key source of market confusion is the overlapping terms and acronyms, including AES, FIPS, Common Criteria, etc. This paper seeks to clarify these labels and explores the suitability of the various approaches to specific test and telemetry requirements.
