NEWEST UPDATED VERSION 2026 |ALREADY GRADED A+
What ways can confidentiality be compromised?
- lose a personal laptop with data
- Person can view your password you are entering in
- Send an email attachment to the wrong person.
- Attacker can penetrate your systems. etc.
integrity
Keeping data unaltered by accidental or malicious intent
How to maintain integrity?
Prevent unauthorized changes to the data and the ability to
reverse unwanted authorized changes.
Via system/file permissions or Undo/Roll back undesirable changes.
,Ways Availability can be compromised
- Power loss
- Application issues
- Network attacks
- System compromised (DoS)
Denial of Service (DoS)
Security problem in which users are not able to access an
information system; can be caused by human errors, natural
disaster, or malicious activity.
Parkerian hexad model
A model that adds three more principles to the CIA triad:
Possession/Control
Utility
Authenticity
,Possession/ control
Refers to the physical disposition of the media on which the data is
stored; This allows you to discuss loss of data via its physical
medium.
Principle of Possession example
Lost package (encrypted USB's and unencrypted
USB's) possession is an issue because the tapes are
physically lost.
(Unencrypted is compromised via confidentiality and possession;
encrypted is compromised only via possession).
Principle of Authenticity
Allows you to say whether you've attributed the data in question
to the proper owner/creator.
Ways authenticity can be compromised
Sending an email but altering the message to look like it came
from someone else, than the original one that was sent.
, Utility
How useful the data is to you.
Ex. Unencrypted (a lot of utility) Encrypted (little utility).
Security Attacks
Broken down from the type of attack, risk the attack represents,
and controls you might use to mitigate it.
Types of attacks
1- interception
2- interruption
3- modification
4- fabrication
Interception
Attacks allows unauthorized users to access our data, applications, or
environments.
Primarily an attack against confidentiality
