Question

A bank system mainframe is struck by a DDoS attack and goes offline. Customer’s cannot log on to their accounts. Which element of C.I.A. has been violated?

Answer 1

Availability

Step-by-step explanation:

C.I.A which in computer engineering means Confidentiality, Integrity, and Availability. It is often referred to as the C.I.A triad.

The C.I.A triad is considered to be three principles of information security. Based on the type of impact on any security breach, can leads to violation of any or more that one of the CIA principles.

Hence, in this case, since the DDoS attack only resulted in the system's mainframe going offline and the prevention of customers to log on to their accounts. This shows that "Availability" which is one of the CIA principles, has been violated.

Availability in this sense is that the customers should have valid access to their resources whenever needed.
