CIA Triad
Confidentiality
Integrity
Availability
Parkerian hexad
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
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
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
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
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
Attribution as to the owner or creator of the data in question.
Authenticity can be enforced through the use of digital signatures.
Utility
Refers to how useful the data is to us.
Interception
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.
