Information is kept confidential or secret from unauthorized users or from

people who are not allowed to see it. For example, credit card transactions

over the internet. As a transaction is made the credit card number is encrypted

by restricting access to the credit card number and users information.

Information can not be modified without detection. Integrity ensures that the

data stored is correct and that no one has altered the data in any way. Data

sent back and forth use protection methods such as hashing and checksums.

The data needs to be protected from modification and deletion by

unauthorized users as well as user mistakes such as file deletion.

Confidentiality

Integrity

Availability

The information created and stored by an organization needs to be available

to authorized users and applications. If data is lost it can be restored using

Availability. Information needs to be be accessible and well taken care of.

Things should be maintained such as redundancy, backups and recovery

features. There should also be some good protection against threats placed

on the system as well.

Technicians should also be trained in proper disaster recovery and backup

plans.

Environmental issues are also a large part of Availability, issues such as

extreme cold and extreme heat can cause big problems with sensitive

equipment.

It takes an equal

combination of all

three, confidentiality,

integrity and

availability to have a

properly running

infrastructure whereas

security is directly in

the middle of the triad.
