,Question 1
CIA Triad
Correct Answer
Confidentiality, Integrity, Availability
Question 2
Parkerian hexad
Correct Answer
Where the CIA triad consists of confidentiality, integrity, and availability, the Parkerian hexad consists of these three
principles, as well as possession or control, authenticity, and utility
Question 3
Confidentiality
Correct Answer
Refers to our ability to protect our data from those who are not authorized to view it.
Confidentiality can be compromised by the loss of a laptop containing data, a person looking over our shoulder
while we type a password, an e-mail attachment being sent to the wrong person, an attacker penetrating our
systems, or similar issues.
Question 4
Integrity
Correct Answer
Refers to the ability to prevent our data from being changed in an unauthorized or undesirable manner. This could
mean the unauthorized change or deletion of our data or portions of our data, or it could mean an authorized, but
undesirable, change or deletion of our data. To maintain integrity, we not only need to have the means to prevent
unauthorized changes to our data but also need the ability to reverse authorized changes that need to be undone.
Question 5
Availability
Correct Answer
refers to the ability to access our data when we need it. Loss of availability can refer to a wide variety of breaks
anywhere in the chain that allows us access to our data. Such issues can result from power loss, operating system or
application problems, network attacks, compromise of a system, or other problems. When such issues are caused by
an outside party, such as an attacker, they are commonly referred to as a denial of service (DoS) attack.

, Question 6
Possession or Control
Correct Answer
Refers to the physical disposition of the media on which the data is stored. This enables us, without involving other
factors such as availability, to discuss our loss of the data in its physical medium
An example is data store be on multiple devices and there could be numerous versions.
Question 7
Authenticity
Correct Answer
Attribution as to the owner or creator of the data in question.
Authenticity can be enforced through the use of digital signatures.
Question 8
Utility
Correct Answer
Refers to how useful the data is to us.
Question 9
Interception
Correct Answer
Interception attacks allow unauthorized users to access our data, applications, or environments and are primarily an
attack against confidentiality. Interception might take the form of unauthorized file viewing or copying,
eavesdropping on phone conversations, or reading e-mail, and can be conducted against data at rest or in motion.
Properly executed, interception attacks can be very difficult to detect.
Affects Confidentiality
Question 10
Interruption
Correct Answer
Interruption attacks cause our assets to become unusable or unavailable for our use, on a temporary or permanent
basis. Interruption attacks often affect availability but can be an attack on integrity as well. In the case of a DoS
attack on a mail server, we would classify this as an availability attack.
