Information Security Principles

Information Security Principles

The principles of information security are based on the CIA concept:

• Confidentiality: ensures restriction access to information.

• Integrity: ensures consistency and inalterability of data.

• Availability: ensures data availability.

Also:

• Non Repudiation: ensures that the sender of information is provided with proof of delivery and the recipient is provided with proof of the sender's identity, so neither can later deny having processed the information.

AAA Services Concept

• Authentication: identity verification Ex: login and password.

• Authorization: user privileges.

• Accounting: generation of logs on user actions in the system.
