Integrity - 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 - 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 - 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 - Answer ✔✔-Attribution as to the owner or creator of the data in
question.
Authenticity can be enforced through the use of digital signatures.
Utility - Answer ✔✔-Refers to how useful the data is to us.
CIA Triad - Answer ✔✔-Confidentiality, Integrity, Availability
Parkerian hexad - 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 - 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.
Interception - 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 - 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.
, Affects Integrity and availability
Modification - Answer ✔✔-Modification attacks involve tampering with our
asset. If we access a file in an unauthorized manner and alter the data it
contains, we have affected the integrity of the data contained in the file.
Fabrication - Answer ✔✔-Fabrication attacks involve generating data, processes,
communications, or other similar activities with a system. Fabrication attacks
primarily affect integrity but could be considered an availability attack as well. If
we generate spurious information in a database, this would be considered to be
a fabrication attack.
Affects Integrity and Availability
Threat - Answer ✔✔-Something that has potential to cause harm
Vulnerability - Answer ✔✔-Weaknesses that can be used to harm us
Risk - Answer ✔✔-Likeliness that something bad will happen
Impact - Answer ✔✔-The value of the asset is used to assess if a risk is present
