What is Information Assurance?

Nearly every aspect of society today depends on computer systems: transportation, communication, banking, and manufacturing, to name a few. However, this infrastructure of computerized systems is increasingly under threat of attack from viruses, worms, hackers, and information thieves. Every business wants to be assured that their information is safe.

Businesses and government agencies need to protect their systems. A computer worm or virus can cause delays and cost money, but information theft can be disastrous. Business information that is stolen from computers can be used to steal money from private accounts or reveal trade secrets. It has even been used to blackmail businesses and individuals. If information is obtained from government sites, the results can have even more dire consequences.

Information assurance refers to the people, hardware, software, policies, and procedures that protect information systems. Definitions of information assurance emphasize that it ensures:

· Information is available when needed

· Integrity of the information is sound

· Authenticity can be verified

· Information is kept confidential

· Proof of the integrity and the origin of the data can be provided

One of the fastest growing fields in computer technology is in information assurance. Although the mission of information assurance has been around for more than 50 years, the development of the computer and, more recently, the ever-increasing use of computer systems for the transfer and storage of information has changed the environment and the necessity for improving the protection of sensitive information.
