DNS and Multilevel Secure Networks: architectures and recommendations
NPS-CS-09-004.pdf (1.345Mb)Abstract
The Domain Name System (DNS) protocol was introduced to solve a naming problem in TCP/IP networking, namely, to provide a translation service of system names to network addresses (i.e., Internet Protocol (IP) addresses). The protocol was not developed with a requirement to support multilevel secure (MLS) networks. However, the Department of Defense (DoD) vision for the Global Information Grid (GIG) entails support for multilevel networks. In the future, DNS installations must securely deal with multilevel issues. This paper describes specific design recommendations for providing MLS DNS in the context of the GIG Vision, and the Monterey Security Architecture (MYSEA) Testbed. It also describes several other potential MLS DNS architectures along with their advantages and disadvantages.

Finite volume element (FVE) discretization and multilevel solution of the axisymmetric heat equation
(Monterey, California. Naval Postgraduate School, 1994-12);The axisymmetric heat equation, resulting from a point-source of heat applied to a metal block, is solved numerically; both iterative and multilevel solutions are computed in order to compare the two processes. The continuum ... -
