Authenticity - CORRECT ANSWERS✅✅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 ANSWERS✅✅Interception
(eaves dropping)
Integrity is affected by what type of attacks? - CORRECT ANSWERS✅✅Interruption
(assets are unusable), modification (tampering with an asset), fabrication (generating false
data)
Authenticity is affected by what type of attacks? - CORRECT ANSWERS✅✅Interruption
(assets are unusable), modification (tampering with an asset), fabrication (generating false

Utility - CORRECT ANSWERS✅✅How useful the data is to you (can be a spectrum, not
just yes or no)
Possession - CORRECT ANSWERS✅✅Do you physically have the data in question? Used
to describe the scope of a loss
Identify the four types of attacks - CORRECT ANSWERS✅✅interception, interruption,
