Information Security
Confidentiality
Assurance that information is shared only among authorised persons or
organisations. Breaches of Confidentiality can occur when data is not handled in
a manner adequate to safeguard the confidentiality of the information
concerned. Such disclosure can take place by word of mouth, by printing,
copying, e-mailing or creating documents and other data etc. The classification
of the information should determine is confidentiality and hence the appropriate
safeguards.

Information Security
Integrity
Assurance that the information is authentic and complete. Ensuring that
information can be relied upon to be sufficiently accurate for its purpose. The
term Integrity is used frequently when considering Information Security as it is
represents one of the primary indicators of security (or lack of it). The integrity
of data is not only whether the data is 'correct', but whether it can be trusted and
relied upon. For example, making copies (say by e-mailing a file) of a sensitive
document, threatens both confidentiality and the integrity of the information.
Why? Because, by making one or more copies, the data is then at risk of change
or modification.

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

methodologies used, and the areas of concentration. Information
security is concerned with the confidentiality, integrity and availability
of data regardless of the form the data may take: electronic, print, or
other forms.
