What is the CIA triad in cybersecurity?

S
Situation
In every cybersecurity role, understanding core principles is fundamental. The CIA triad is the most basic framework.
T
Task
Explain the three pillars that form the foundation of all information security programs.
A
Action
Confidentiality ensures data is accessible only to authorized parties (encryption, access controls). Integrity ensures data is not tampered with (hashing, checksums, digital signatures). Availability ensures systems and data are accessible when needed (redundancy, backups, DDoS protection). Every security control maps to one or more of these pillars.
R
Result
Organizations use the CIA triad to design security policies, assess risks, and prioritize investments. This framework guides all security decision-making from policy creation to incident response.
