    • PKI 
    • Hashing
  13. An information system owner has supplied a new requirement to the development team that calls for increased non-repudiation within the application. After undergoing several audits, the owner determined that current levels of non-repudiation were insufficient.

    Which of the following capabilities would be MOST appropriate to consider implementing is response to the new requirement?

    • Transitive trust
    • Symmetric encryption
    • Two-factor authentication
    • Digital signatures 
    • One-time passwords
  14. Joe a website administrator believes he owns the intellectual property for a company invention and has been replacing image files on the company’s public facing website in the DMZ. Joe is using steganography to hide stolen data.

    Which of the following controls can be implemented to mitigate this type of inside threat?

    • Digital signatures
    • File integrity monitoring
    • Access controls
