Define the confidentiality in the CIA triad. -
CORRECT -Our ability to protect data from those
who are not authorized to view it.
Examples of confidentiality - CORRECT -A patron
using an ATM card wants to keep their PIN number confidential.

,How do you control integrity? - CORRECT -
Permissions restrict what users can do (read, write, etc.)

Denial of Service attack.
Define information security. - CORRECT -The

unauthorized access, use, disclosure, disruption, modification, or
destruction in order to provide confidentiality, integrity, and
availability.
Define the Parkerian Hexad and its principles. -
CORRECT -The Parkerian Hexad includes
, confidentiality, integrity, and availability from the CIA triad. It
also includes possession (or control), authenticity, and utility.
Authenticity - CORRECT -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? -
CORRECT -Interception (eaves dropping)
Integrity is affected by what type of attacks? -
CORRECT -Interruption (assets are unusable),
modification (tampering with an asset), fabrication (generating
false data)
Authenticity is affected by what type of attacks? -
CORRECT -Interruption (assets are unusable),
modification (tampering with an asset), fabrication (generating
false data)
Utility - CORRECT -How useful the data is to you
(can be a spectrum, not just yes or no)
