QUESTION:392Which of the following implementation modes would provide the GREATEST amountof security for outbound data connecting to the internet?A. Transport mode with authentication header (AH) plus encapsulating security payload(ESP)B. Secure Sockets Layer (SSL) modeC. Tunnel mode with AH plus ESPD. Triple-DES encryption modeAnswer:CExplanation:Tunnel mode provides protection to the entire IP package. To accomplish this, AH andESP services can be nested. The transport mode provides primary protection for thehigher layers of the protocols by extending protection to the data fields (payload) of anIP package. The SSL mode provides security to the higher communication layers(transport layer). The triple-DES encryption mode is an algorithm that providesconfidentiality
QUESTION:393Which of the following is the MOST reliable sender authentication method?
Explanation:Digital certificates are issued by a trusted third party. The message sender attaches thecertificate and the recipient can verify authenticity with the certificate repository.Asymmetric cryptography, such as public key infrastructure ( PKl ), appears toauthenticate the sender but is vulnerable to a man-in-the-middle attack. Digital signaturesare used for both authentication and confidentiality, but the identity of the sender wouldstill be confirmed by the digital certificate. Message authentication code is used formessage integrity verification.QUESTION:394Which of the following provides the GREATEST assurance of message authenticity?
