Confidentiality, integrity, and availability
CIA is an acronym representing the core principles of information security: confidentiality, integrity, and availability. These principles are fundamental to designing and implementing secure systems and are often called the CIA triad:
- Confidentiality ensures that information is only accessible to those with authorized permissions. Software security involves encryption, access controls, and user authentication to protect sensitive data from unauthorized access.
- Integrity ensures that information remains accurate and unaltered during storage, processing, or transmission. In software security, techniques such as data validation, checksums, digital signatures, and version control are used to maintain data and software integrity.
- Availability ensures that information and resources are available and accessible when needed. Software security involves measures to prevent and mitigate disruptions, such as redundancy, failover systems...
