Information Assurance is the confidence that information systems will protect
the information they handle and will function as they need to, when they need
to, under the control of legitimate users.
There is little information
that exists that will not at one time or another be stored or transmitted
electronically.
Information on paper as soon as it is fixed or input
into a computer, enters the electronic world. From here the information can be
changed, deleted or broadcast to the world.
Electronic information
must be readily available when needed and trusted to be accurate. Sometimes
there are confidentiality concerns. Ensuring the confidentiality, availability
and integrity of all electronically held information is the goal. "Information
Assurance" is the term we use to describe this goal.
Through the use
of appropriate security products and procedures we hope to achieve reasonable
assurance that electronic information is adequately protected from unauthorised
change or dissemination and ensure the information is always available.
Helping the owners of electronic information to determine the products and
procedures to achieve Information Assurance is what CESG is here for.
