Availability means that information is accessible to authorized individuals when they need it. For example, a company’s website should be available to customers 24/7.

The CIA triad is important because it provides a framework for organizations to protect their information from unauthorized access, modification, or destruction.

Examples:

• Confidentiality: A company uses encryption to protect its customer database from unauthorized access.
• Integrity: A company uses checksums to verify the integrity of its financial database.
• Availability: A company uses a load balancer to distribute traffic across multiple servers, so that its website remains available even if one server fails.

It is important to note that the CIA triad is not mutually exclusive. For example, an organization may implement a security measure that improves confidentiality and availability, but reduces integrity. For example, an organization may encrypt its customer database, which improves confidentiality and availability, but makes it more difficult to audit the database for accuracy.

Organizations must carefully balance the three principles of the CIA triad to meet their specific security needs.
