The Data-At-Rest Encryption Series white papers are aimed to provide engineers, system architects, and program managers with background information, technical details, and a methodology for selecting a data-at-rest (DAR) security approach. The series is meant for professionals developing deployed systems that host classified data.
The first in the series, Data Threats and Protection, explores the reasons to protect DAR, encryption basics, and National Security Agency (NSA) programs, namely Commercial Solutions for Classified (CSfC) and Type 1. Both NSA CSfC and Type 1 are encryption programs that support the protection of classified DAR. This paper is aimed to provide engineers, system architects, and program managers with background information, technical details, and a methodology for selecting a DAR security approach.
