Information security - What is it?

Information security is the discipline that deals with the following three attributes:

Confidentiality is the assurance that information is shared only among authorized persons or organizations.

Integrity is the assurance that the information is authentic, complete and can be relied upon to be sufficiently accurate for its purpose.

Availability is the assurance that the systems responsible for delivering, storing and processing information are accessible when needed by those who need them.

Loss of any of the above attributes in a corporate data network characterizes an information security breach.

In an economy where organizations are highly dependent on the immediate availability of reliable information, security weakness frequently threatens the continued existence of the corporate entity. It is imperative that IT professionals implement the technology and processes that mitigate that risk.

He dabbled in website building and web hosting when DHTML and frames were en vogue and started writing about the impact of technology on society just before the start of the Y2K hysteria at the turn of the last millennium. Following an eight-year stint at where he discovered the joys of global tech-fests, Désiré now heads up TechRadar Pro. Previously he was a freelance technology journalist at Incisive Media, Breakthrough Publishing and Vnunet, and Business Magazine. He also launched and hosted the first Tech Radio Show on Radio Plus.
