Your organization has decided that it needs to protect all confidential data that is residing on a file server. All confidential data is located within a folder named Confidential. You need to ensure that this data is protected. What should you do?
a. Implement hashing for all files within the Confidential folder.
b. Decrypt the Confidential folder and all its contents.
c. Encrypt the Confidential folder and all its contents.
d. Implement a digital signature for all the users that should have access to the Confidential folder.
Answer: C. Explanation: You should encrypt the folder and all its contents. Hashing reduces a message to a hash value. Hashing is a method for determining whether the contents of a file have been changed. But hashing does not provide a means of protecting data from editing. Decryption converts ciphertext into plaintext. A digital signature is an object that provides sender authentication and message integrity by including a digital signature with the original message.
