A systems administrator is working with a third party to establish the automated transfer of large amounts of proprietary data. The interface will need to use secured
credentials and the transmission will consist of data that has been encrypted prior to transit and needs no additional protection. Which of the following would be the
MOST efficient method of data transmission given the established requirements?
A.
SSH
B.
TFTP
C.
FTP
D.
FTPS
Why this is SSH? Who can explain this?
TFTP is FTP without authentication so that’s not the answer. For FTP, authentication is in clear text so that won’t provide the “secure credentials” as stated in the question. SSH will provide the secure authentication requested by the question, but I don’t think SSH should be the answer either as SSH itself does not provide file transfer functions. Both SFTP and FTPS provide secure authentication and file data transfer, but SFTP is not listed as an option in the answers. I think the question is poorly worded – what do they imply by “data has been encrypted prior to transit and needs no additional protection”? Even if SSH is the correct answer, once the SSH connection is established, all communication data is encrypted – so the statement “data has been encrypted prior to transit and needs no additional protection” doesn’t really add to anything. In summary, I think this question and its list of answer options are not well thought out.
I would go for “FTPS”
FTPS is Secure FTP, much like HTTPS is secure HTTP, and runs over SSL (Secure Sockets Layer) and TLS (Transport Layer Security). The user credentials and data are no longer sent in the clear; instead they are encrypted before they’re transmitted.
Client software also has the flexibility, if it’s allowed by the server, to encrypt only parts of the communication, not all of it. This might seem counterintuitive based on the discussion so far.
But if the files being transferred are already encrypted, or if no information of a sensitive nature is being transferred, then it’s likely ok not to incur the overhead that encryption requires.
I tend to agree w/ Bryan.

A software development company needs to share information between two remote servers, using encryption to protect it. A programmer suggests developing a new encryption protocol, arguing that using an unknown protocol with secure, existing cryptographic algorithm libraries will provide strong encryption without being susceptible to attacks on other known protocols. Which of the following summarizes the BEST response to the programmer’s proposal?
A. The newly developed protocol will only be as secure as the underlying cryptographic algorithms used.
B. New protocols often introduce unexpected vulnerabilities, even when developed with otherwise secure and tested algorithm libraries.
C. A programmer should have specialized training in protocol development before attempting to design a new encryption protocol.
D. The obscurity value of unproven protocols against attacks often outweighs the potential for introducing new vulnerabilities.
Answer: B
NEW QUESTION 82
A security technician would like to obscure sensitive data within a file so that it can be transferred without causing suspicion. Which of the following technologies would BEST be suited to accomplish this?
A. Transport Encryption
B. Stream Encryption
C. Digital Signature
D. Steganography
Answer: D
Explanation:
Steganography is the process of hiding a message in another message so as to obfuscate its importance. It is also the process of hiding a message in a medium such as a digital image, audio file, or other file. In theory, doing this prevents analysts from detecting the real message. You could encode your message in another file or message and use that file to hide your message.

Which of the following attack types is being carried out where a target is being sent unsolicited messages via Bluetooth?
A. War chalking
B. Bluejacking
C. Bluesnarfing
D. Rogue tethering
Answer: B
Explanation:
Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i.e., for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol.
NEW QUESTION 85
Joe is exchanging encrypted email with another party. Joe encrypts the initial email with a key. When Joe receives a response, he is unable to decrypt the response with the same key he used initially. Which of the following would explain the situation?
A. An ephemeral key was used for one of the messages.
B. A stream cipher was used for the initial email; a block cipher was used for the reply.
C. Out-of-band key exchange has taken place.
D. Asymmetric encryption is being used.
Answer: D
Explanation:
Asymmetric algorithms use two keys to encrypt and decrypt data. These asymmetric keys are referred to as the public key and the private key. The sender uses the public key to encrypt a message, and the receiver uses the private key to decrypt the message; what one key does, the other one undoes.
