The CIA Triad — Confidentiality, Integrity, Availability
Every security decision you'll ever make traces back to three properties — the "CIA Triad." Confidentiality: data is only readable by those authorized to see it (encryption, access controls). Integrity: data is accurate and unmodified (hashing, digital signatures). Availability: systems are reachable when needed (redundancy, backups, DDoS defense).
Self-check: a payroll record's SHA-256 hash changes by one character.
