ABSTRACT
After studying security mechanisms in cells, we found that
security mechanisms are present in nearly every cell com-
ponent. Cells follow a multilayered, defense-in-depth
approach to security. In this entry, we offer a framework
that examines the similarities between cell security and
network security. In today’s high-technology environment,
in which security is increasingly important, this framework
can help us by stimulating thinking about security while
offering a model about how to design secure systems.
