What are the 7 principles of security?

The seven principles of security are confidentiality, integrity, availability, accountability, non-repudiation, authentication, and authorization.

  1. Confidentiality refers to the idea that information should only be accessible to those who are authorized to access it.
  2. Integrity refers to the concept that information should not be modified without proper authorization.
  3. Availability refers to the idea that authorized users should have access to the information they need, when they need it.
  4. Accountability means that there is a clear chain of responsibility for actions taken with regard to information security.
  5. Non-repudiation means that the actions of an individual or system can be traced back to them and cannot be denied.
  6. Authentication is the process of verifying that a user is who they claim to be.
  7. Authorization refers to the process of granting or denying access to resources based on a user’s credentials and permissions.
