CIA Triad
The CIA Triad is a fundamental concept in information security that stands for Confidentiality, Integrity, and Availability. Think of it as a simple checklist that security professionals use to make sure information and systems are properly protected. Confidentiality means keeping sensitive information private, like making sure only authorized people can see customer data. Integrity ensures information hasn't been tampered with, like making sure financial records are accurate. Availability means systems and data are accessible when needed, like keeping websites running 24/7. When you see this term in resumes, it shows the candidate understands basic security principles.
