The core principles of information security are defined by the CIA Triad:
- Confidentiality: Ensuring data is accessible only to authorized users (e.g., encryption, access controls).
- Integrity: Protecting data from unauthorized modification (e.g., checksums, digital signatures).
- Availability: Guaranteeing systems and data are accessible when needed (e.g., backups, DDoS protection).
Additional principles include non-repudiation (preventing denial of actions) and risk management (identifying and mitigating threats).
