Which of the following is one of the three core principles of information security?

• A. Location tracking
• B. Integrity
• C. GDPR
• D. Malicious

Answer: (B)

Preserving data integrity means ensuring information remains accurate and unaltered by unauthorized actors during storage and transmission. This is essential because decisions, transactions, and records rely on data that reflects the truth of what happened. If data is tampered with, you could end up acting on wrong information, leading to financial loss or loss of trust. To protect integrity, organizations use checks like hash values, digital signatures, version control, access controls, and audit trails so any unauthorized changes are detectable and reversible. Confidentiality and availability are the other two widely recognized parts of the triad: confidentiality guards who can see the data, and availability ensures data and services are accessible when needed. Privacy regulations like GDPR address data protection rights, not a security principle by itself. Location tracking describes a capability, not a principle, and “malicious” is a descriptor, not a principle.
