Which CIA Goal? — TechKnowSurge

About this interactive

The Data Protection lesson asks what we are protecting data from, and answers with two triads that mirror each other. The CIA triad is the goal: confidentiality, integrity and availability. The DAD triad is what goes wrong: disclosure (the data is seen by someone who should not see it), alteration (the data changes and is no longer accurate) and denial (users cannot get to it). Integrity: first notice that data changed. Keep duplicate copies and compare them (three copies show which one changed), or keep a hash, a fingerprint that changes if the data does. A parity bit is added so a group of bits always adds up to an odd (or even) number, so a flipped bit shows up. When bad data is found, data scrubbing puts it right. Availability: keep the data there when users need it. Replicate a database, take backups, and copy the whole setup to a second site to fail over to. Confidentiality: keep data from the wrong eyes. The surest way is not to have it at all; otherwise limit access to it, or conceal it. A quick test for each card: does it guard against the data being seen, being changed, or being unreachable?

What you'll learn

Match a data protection measure, or a failure, to the goal of the CIA triad it serves or breaks: confidentiality, integrity or availability
Recognize the DAD triad as the failures: disclosure breaks confidentiality, alteration breaks integrity, and denial breaks availability

Key terms

CIA Triad: The three core principles of information security: Confidentiality, Integrity, and Availability.
Confidentiality: The principle that information is accessible only to those authorized to access it.
Integrity: The assurance that data has not been tampered with and remains accurate and complete.
Availability: The assurance that systems and data are accessible and operational when needed by authorized users.
Parity Bit: An extra bit added to a binary sequence to detect errors by ensuring the total number of set bits is odd or even.
Hash Function: A mathematical algorithm that converts input data of any size into a fixed-size output value used to verify data integrity.
