Identifying Methods for Ensuring Confidentiality

1. Break Down the Problem

   • The question asks to identify two methods that specifically ensure confidentiality from a list of security concepts.

2. Relevant Concepts

   • Confidentiality refers to safeguarding information from unauthorized access. The methods provided include:
     • Encryption: This is the primary method for ensuring confidentiality by converting information into a code to prevent unauthorized access.
     • Integrity: This ensures that data is accurate and unaltered but does not directly pertain to confidentiality.
     • Authentication: This verifies the identity of users but is not a method to ensure confidentiality.
     • Availability: This ensures that information is accessible but does not relate to keeping data secret.
     • Authorization: This determines who has access to the information but does not directly safeguard confidentiality.
     • Non-repudiation: This ensures that a user cannot deny actions they have taken but is not focused on confidentiality.

3. Final Answer

   • The two methods that ensure confidentiality are:
     1. Encryption
     2. Authorization

These methods work together to protect sensitive information from being accessed by unauthorized parties.
