• Authentication: The process of verifying the identity of a user or system before granting access to resources.

Integrity

Integrity ensures that information remains accurate and unaltered during its lifecycle. This means that data should not be modified or tampered with by unauthorized entities. Techniques to maintain integrity include hashing, checksums, and digital signatures.

• Hashing: A method of converting data into a fixed-size string of characters, which is unique to the original data.
• Checksums: A value calculated from a data set to verify its integrity during transmission or storage.
• Digital Signatures: A cryptographic technique that verifies the authenticity and integrity of a message or document.

Availability

Availability ensures that information and resources are accessible to authorized users when needed. This aspect is crucial for maintaining business operations, especially in industries reliant on real-time data. Techniques to enhance availability include redundancy, failover systems, and regular maintenance.

• Redundancy: The duplication of critical components or systems to ensure continuous operation in case one fails.
• Failover Systems: Backup systems that automatically take over in the event of a primary system failure.
• Regular Maintenance: Routine checks and updates to systems to prevent downtime and vulnerabilities.
