What are the three goals of information security, known as the CIA triad?

Options

  1. Confidentiality, integrity, availability (Correct option)
  2. Compilation, installation, authentication
  3. Cryptography, identity, authorization
  4. Cloud, internet and access management

Answer

Confidentiality, integrity, availability

Why

  • Confidentiality: only authorized people can read the information (NIST: preserving authorized restrictions on information access and disclosure).
  • Integrity: the information cannot be changed in an unauthorized or unnoticed way.
  • Availability: the information and the system are usable when needed.

Example: encrypting data protects confidentiality, hashes and signatures protect integrity, backups and redundancy protect availability.

Remember

CIA = confidentiality, integrity, availability.
