Abstract
Essentially, information security is a collection of
processes and tools necessary for protecting data
from unauthorized access, use and modification.
Encryption is a technology that obscures information
to make it unreadable without special knowledge or
credentials, such as a password or security token. While traditional network access controls and
perimeter defenses are effective measures for
protecting data files stored in a fixed and relatively
secure location, encryption is the best way to protect
electronic data that is subject to movement – and
today, all electronic information is subject to
movement.
Typically encryption technology is used to protect two basic types of information: data in
motion (or data in transit) and data at rest (or stored data). While network encryption is a
ubiquitous technology, it only protects data in transit, leaving a significant source of
vulnerability left unchecked. In order to protect valuable information assets against identity
theft and other cyber-crimes of the new millennium, organizations must also employ
encryption for data at rest: specifically, data stored on the hard drives of corporate PCs. For
these devices, full-disk data encryption provides the most comprehensive and cost-effective
baseline for information security.
