Computer information security is the ongoing process of exercising due care and due diligence to protect information systems, from unauthorised access, use, disclosure, destruction, modification, or disruption or distribution.
Core Computer Security components, or qualities, can be considered within three areas; Confidentiality, Integrity and Availability (the so called “CIA triad”).
Governments, military, corporations, financial institutions, hospitals, and private businesses amass a great deal of confidential information about their employees, customers, products, research, and financial status.
Most of this information is now collected, processed and stored on computers and transmitted across computer networks to other computers.
Should confidential information about a business' customers or finances or new product line fall into the hands of a competitor, such a breach of security could lead to lost business, law suits or even bankruptcy of the business.
Protecting confidential information is a business requirement, and in many cases also an ethical and legal requirement.
ConfidentialityConfidentiality is the term used to prevent the disclosure of information to unauthorised individuals or systems.
For example, a credit card transaction on the Internet requires the credit card number to be transmitted from the buyer to the merchant and from the merchant to a bank payment processing network.
