Ah yes, the good ol' CIA triad that is vital, and in all honesty is the foundation of cybersecurity. Typically, for my fellow junior analysts here, I wouldn't find it surprising if for almost every other interview you had been asked the question "What is the CIA Triad?". Now for those of you who don't know what this is, I suggest jotting this down in your notes since not only is it more likely that not this will come up for that job you really wanted but better yet just to appreciate the cybersecurity field by doing your homework on it.
What is the CIA Triad?
Well from fortinet.com they describe it as: 'The three letters in "CIA triad" stand for Confidentiality, Integrity, and Availability. The CIA triad is a common model that forms the basis for the development of security systems. They are used for finding vulnerabilities and methods for creating solutions.'
In my own words I try not to make it harder for myself to memorize so I will share with you a fairly easy way to remember the CIA Triad and what each one of these letters do.
CIA is an abbreviation of the 3 pillars of info. sec - Confidentiality, Integrity, and Availability:
Confidentiality - ensures that data isn’t made available to unauthorized users
Integrity - ensures that data cannot be altered/modified by unauthorized users
Availability - ensures that data is accessible at all times
