The CIA Triad
The foundational security model of Confidentiality through encryption and access controls, Integrity through hashing and digital signatures, and Availability through redundancy and DDoS protection.
Why this matters
It is the universal language of risk, and every security failure can be traced back to a violation of one or more of these three pillars.
Core concepts
Confidentiality via encryption and access controls Integrity via hashing and digital signatures Availability via redundancy and DDoS mitigation Authentication and non-repudiation
Practical skills
Classify a real-world breach into specific CIA triad failures and identify which control category would have prevented it.
Common mistakes
Treating the three pillars as independent instead of interconnected Applying encryption for confidentiality while neglecting hashing for integrity
Mini project
Analyze the 2017 Equifax breach report and write a one-page summary mapping every identified failure to the CIA triad.
