ISC copyright Security Professional (copyright) Sample Questions (Q1321-Q1326):

NEW QUESTION # 1321
Cryptography does NOT help in:

  • A. Detecting fraudulent insertion.
  • B. Detecting fraudulent deletion.
  • C. Detecting fraudulent modification.
  • D. Detecting fraudulent disclosure.

Answer: D

Explanation:
Cryptography is a detective control in the fact that it allows the detection of fraudulent insertion, deletion or modification. It also is a preventive control is the fact that it prevents disclosure, but it usually does not offers any means of detecting disclosure.

NEW QUESTION # 1322
Which of the following offers security to wireless communications?

  • A. S-WAP
  • B. WDP
  • C. WSP
  • D. WTLS

Answer: D

Explanation:
Wireless Transport Layer Security (WTLS) is a communication protocol that allows wireless devices to send and receive encrypted information over the Internet. S-
WAP is not defined. WSP (Wireless Session Protocol) and WDP (Wireless Datagram
Protocol) are part of Wireless Access Protocol (WAP).

NEW QUESTION # 1323
What would you call the process that takes advantages of the security provided by a transmission protocol by carrying one protocol over another?

  • A. Concealing
  • B. Steganography
  • C. Piggy Backing
  • D. Tunneling

Answer: D

Explanation:
Computer networks use a tunneling protocol when one network protocol (the delivery protocol) encapsulates a different payload protocol. By using tunneling one can
(for example) carry a payload over an incompatible delivery-network, or provide a secure path through an untrusted network.
Tunneling typically contrasts with a layered protocol model such as those of OSI or TCP/IP.
The delivery protocol usually (but not always) operates at a higher level in the model than does the payload protocol, or at the same level.
To understand a particular protocol stack, network engineers must understand both the payload and delivery protocol sets.
As an example of network layer over network layer, Generic Routing Encapsulation (GRE), a protocol running over IP (IP Protocol Number 47), often serves to carry IP packets, with
RFC 1918 private addresses, over the Internet using delivery packets with public IP addresses. In this case, the delivery and payload protocols are compatible, but the payload addresses are incompatible with those of the delivery network.
Secure Shell tunneling
A Secure Shell (SSH) tunnel consists of an encrypted tunnel created through a SSH protocol connection. Users may set up SSH tunnels to transfer unencrypted traffic over a network through an encrypted channel. For example, Windows machines can share files using the Server Message Block (SMB) protocol, a non-encrypted protocol. If one were to mount a Microsoft Windows file-system remotely through the Internet, someone snooping on the connection could see transferred files. To mount the Windows file-system securely, one can establish an SSH tunnel that routes all SMB traffic to the remote fileserver through an encrypted channel. Even though the SMB protocol itself contains no encryption, the encrypted SSH channel through which it travels offers security.
Tunneling to circumvent firewall policy
Users can also use tunneling to "sneak through" a firewall, using a protocol that the firewall would normally block, but "wrapped" inside a protocol that the firewall does not block, such as HTTP. If the firewall policy does not specifically exclude this kind of "wrapping", this trick can function to get around the intended firewall policy.
Another HTTP-based tunneling method uses the HTTP CONNECT method/command. A client issues the HTTP CONNECT command to a HTTP proxy. The proxy then makes a
TCP connection to a particular server:port, and relays data between that server:port and the client connection. Because this creates a security hole, CONNECT-capable HTTP proxies commonly restrict access to the CONNECT method. The proxy allows access only to a whitelist of specific authorized servers.
The following answers are incorrect:
Piggy Backing
In security, piggybacking refers to when a person tags along with another person who is authorized to gain entry into a restricted area, or pass a certain. The act may be legal or illegal, authorized or unauthorized, depending on the circumstances. However, the term more often has the connotation of being an illegal or unauthorized act.
To describe the act of an unauthorized person who follows someone to a restricted area without the consent of the authorized person, the term tailgating is also used. "Tailgating" implies without consent (similar to a car tailgating another vehicle on the freeway), while
"piggybacking" usually implies consent of the authorized person.
Piggybacking came to the public's attention particularly in 1999, when a series of weaknesses were exposed in airport security. While a study showed that the majority of undercover agents attempting to pass through checkpoints, bring banned items on planes, or board planes without tickets were successful, piggybacking was revealed as one of the methods that was used in order to enter off-limits areas.
Steganography
Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means
"concealed writing" from the Greek words steganos () meaning "covered or protected", and graphein () meaning "to write". The first recorded use of the term was in 1499 by Johannes
Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.
The advantage of steganography, over cryptography alone, is that messages do not attract attention to themselves. Plainly visible encrypted messages-no matter how unbreakable-will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal. Therefore, whereas cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties.
Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size. As a simple example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it.
Concealing
Concealment (also called abscondence or hiding) is obscuring something from view or rendering it inconspicuous, the opposite of exposure. A military term is CCD: camouflage
(object looks like its surroundings), concealment (object cannot be seen), and deception
(object looks like something else); in a broad sense, all three are forms of concealment.
The objective of hiding is often to keep the presence of an object or person secret, but in other cases not the presence is a secret, but only the location.

NEW QUESTION # 1324
A back door into a network refers to what?

  • A. Monitoring programs implemented on dummy applications to lure intruders
  • B. Mechanisms created by hackers to gain network access at a later time
  • C. Socially engineering passwords from a subject
  • D. Undocumented instructions used by programmers to debug applications

Answer: B

Explanation:
Back doors are very hard to trace, as an intruder will often create several avenues into a network to be exploited later. The only real way to be sure these avenues are closed after an attack is to restore the operating system from the original media, apply the patches, and restore all data and applications.
*social engineering is a technique used to manipulate users into revealing information
like passwords.
*Answer "Undocumented instructions used by programmers to debug
applications"refers to a trap door, which are undocumented hooks into an application to assist
programmers with debugging. Although intended innocently, these can be
exploited by intruders.
*"Monitoring programs implemented on dummy applications to lure
intruders" is a honey pot or padded cell.
A honey pot uses a dummy server with bogus applications as a
decoy for intruders. Source: Fighting Computer Crime by Donn B.
