,CIA Triad
- correct answer Confidentiality, Integrity, Availability
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
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.
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.
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.
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.
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.
Utility
- correct answer Refers to how useful the data is to us.
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
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.
