Questions and Answer | 2026 Update
Define the confidentiality in the CIA triad. - ANSWER✔✨-Our ability to protect data from those
who are not authorized to view it.
Examples of confidentiality - ANSWER✔✨-A patron using an ATM card wants to keep their PIN
number confidential.
An ATM owner wants to keep bank account numbers confidential.
How can confidentiality be broken? - ANSWER✔✨-Losing a laptop
An attacker gets access to info
A person can look over your shoulder
Define integrity in the CIA triad. - ANSWER✔✨-The ability to prevent people from changing
your data and the ability to reverse unwanted changes.
How do you control integrity? - ANSWER✔✨-Permissions restrict what users can do (read,
write, etc.)
Examples of integrity - ANSWER✔✨-Data used by a doctor to make medical decisions needs to
be correct or the patient can die.
, Define the availability in the CIA triad. - ANSWER✔✨-Our data needs to be accessible when we
need it.
How can availability be broken? - ANSWER✔✨-Loss of power, application problems. If caused
by an attacker, this is a Denial of Service attack.
Define information security. - ANSWER✔✨-The protection of information and information
systems from unauthorized access, use, disclosure, disruption, modification, or destruction in
order to provide confidentiality, integrity, and availability.
Define the Parkerian Hexad and its principles. - ANSWER✔✨-The Parkerian Hexad includes
confidentiality, integrity, and availability from the CIA triad. It also includes possession (or
control), authenticity, and utility.
Authenticity - ANSWER✔✨-Whether the data in question comes from who or where it says it
comes from (i.e. did this person actually send this email?)
Confidentiality is affected by what type of attack? - ANSWER✔✨-Interception (eaves dropping)
Integrity is affected by what type of attacks? - ANSWER✔✨-Interruption (assets are unusable),
modification (tampering with an asset), fabrication (generating false data)
Authenticity is affected by what type of attacks? - ANSWER✔✨-Interruption (assets are
unusable), modification (tampering with an asset), fabrication (generating false data)
Utility - ANSWER✔✨-How useful the data is to you (can be a spectrum, not just yes or no)
