Which trio guides protection goals to keep data secret, accurate, and accessible to authorized users?

• A. NIST Framework
• B. MITRE ATT&CK
• C. TLS, PKI, SSH
• D. Confidentiality, Integrity, Availability

Answer: (D)

The main concept being tested is the CIA triad—confidentiality, integrity, and availability. Confidentiality means keeping data secret from unauthorized parties, typically through access controls and encryption. Integrity ensures data remains accurate and trustworthy, protected from unauthorized modification via mechanisms like hashing and digital signatures. Availability guarantees that data and systems are accessible to authorized users when needed, supported by redundancy, backups, and reliable services. Together, these three goals define what protections are needed to keep information secret, accurate, and accessible to those allowed to use it. Other options point to frameworks, attacker knowledge bases, or specific security controls, but they don’t embody the trio of protection goals itself.
