These types of core concepts will be the compass through which security professionals navigate decisions and trade-offs. They help reply why certain adjustments are necessary plus what goals many of us are trying in order to achieve. Several foundational models and concepts slowly move the design in addition to evaluation of secure systems, the nearly all famous being typically the CIA triad and even associated security guidelines. ## The CIA Triad – Confidentiality, Integrity, Availability In the middle of information safety (including application security) are three principal goals: 1. **Confidentiality** – Preventing illegal use of information. In simple terms, trying to keep secrets secret. Just those who are usually authorized (have typically the right credentials or permissions) should get able to look at or use sensitive data.
