These types of core concepts are usually the compass in which security professionals understand decisions and trade-offs. They help remedy why certain handles are necessary and what goals all of us are trying in order to achieve. Several foundational models and guidelines slowly move the design plus evaluation of protected systems, the most famous being the particular CIA triad and even associated security concepts. ## The CIA Triad – Privacy, Integrity, Availability In the middle of information safety measures (including application security) are three major goals: 1. **Confidentiality** – Preventing illegal use of information. Within simple terms, keeping secrets secret. Only those who will be authorized (have typically the right credentials or permissions) should end up being able to watch or use sensitive data. According to NIST, confidentiality signifies "preserving authorized constraints on access and disclosure, including means for protecting individual privacy and amazing information" PTGMEDIA.

A real-world example of this is an SQL injection attack of which dumps all customer records from a database: data that should are actually secret is confronted with typically the attacker. The other regarding confidentiality is disclosure PTGMEDIA. PEARSONCMG.
