Question

In these weeks readings, we learned about the CIA Triad and how each exhibits dependence on the other. Give examples of how failure of one security property (confidentiality/integrity/availability) can lead to the failure of the others. How does a password or authentication relate to this situation?

Answer 1

Answer:

Confidentiality, integrity, and availability make up the CIA (or security) triad. We rely on each prong of this triangle for the purpose of keeping our resources secure and unaltered.

Explanation:

Confidentiality, integrity, and availability make up the CIA (or security) triad. We rely on each prong of this triangle for the purpose of keeping our resources secure and unaltered. For example, if a person intercepts data we are sending, then confidentiality has been breached and data is no longer secure. In the same light, if a person changes data stored in files than that integrity has been compromised. Finally, if there is a disruption, due to nature or human error/malice, availability is lost. Loss of one security directly effects the other factors of the triad.

Let’s take the loss of availability into consideration. A major hurricane hits the east coast. This hurricane causes a massive power outage. For the reason being that major hurricanes do not occur on the east coast, security teams did not account for this sort of natural disaster. As a result, many people are unable to access files or applications on their computer; servers are down all over the east and people are now not able to log into bank accounts, stock portfolios, etc. This is a major loss of information.

Password are kept secret because they need not to be shared. Password is used to shield information. The CIA triad requires that organizations and individual users must always take caution in maintaining confidentiality, integrity and availability of information and password is a means.
