A. Ease of use increases and functionality decreases <p>B. Functionality increases and ease of use decreases</p> <p>C. Ease of use increases and functionality increases</p> <p>D. Functionality decreases and ease of use decreases</p> <p> </p>
The Correct answer is "D". Since, in Cybersecurity field, we have a triple constraint, similar to Project Management, which are: Security, Ease of Use, and Functionality. Any increase/decrease in one of them will lead to decrease/increase in the other two.
For example, if we need to add a fingerprint scan for our information system, for more protection, beside the existence Password login, this will lead to increase the Security, but unfortunately, a lot of users will find out that it become harder to use it and at the same time, because of False Positives cases, it will become less functional. Notice, False Positive is a case where a registered authenticated users has been denied access to the system.
So, in conclusion, as an Information Security Specialists, our job is how to balance between these triple constraints to make the system more reliable and in acceptable level.
If you do it right and together it is C, but if you implement it solo, without informing and listening to the work floor it will be D
