Single Answer
0Myrsini needs to secure files sent from workstation A via the Internet service (C) to remote server E. What is the best method?
Answer Options
A
Use AES at rest at point A, and use TLS in transit via B and D.
B
Encrypt the data files and send them.
C
Use 3DES and TLS to provide double security.
D
Use full-disk encryption at A and E, and use SSL at B and D.
Correct Answer: B
Explanation
Sending a file that is encrypted before it leaves means that exposure of the file in transit will not result in a confidentiality breach, and the file will remain secure until decrypted at location E. Since options A, C, and D do not provide any information about what happens at point C, they should be considered insecure, as the file may be at rest at point C in an unencrypted form.
