Goals of Computer Security (CIA+)

Effective network security hinges on several fundamental principles, often referred to as the CIA triad, supplemented with additional considerations:

• Confidentiality:

  • Ensures that sensitive information is accessible only to authorized individuals. Encryption and access controls are common methods to achieve confidentiality.

• Integrity:

  • Guarantees that data remains accurate and unaltered during storage and transmission. Measures like hashing and checksums help verify data integrity.

• Availability:

  • Ensures that data and services are accessible when needed by authorized users. This includes maintaining hardware, implementing redundancy, and planning for disaster recovery.

• Additional Principles:

  • Authenticity: Verifying the identity of users and systems.
  • Reliability: Ensuring systems perform consistently and correctly over time.
