A company is designing an application that will host customer data. They need to ensure that data at rest is encrypted and that only authorized services and users can access it. Which security principle is primarily addressed by implementing these measures?
- AConfidentiality
- BScalability
- CElasticity
- DHigh Availability
Show answer & explanationAnswer & explanation
Correct answer: A. Confidentiality
Confidentiality is the principle that prevents unauthorized disclosure of information. Encrypting data at rest and implementing strict access controls directly address confidentiality by ensuring that only authorized entities can view or access sensitive data.
Why the other options are wrong
- B. Scalability refers to a system's ability to handle increased workload by adding resources.
- C. Elasticity is the ability to automatically scale resources up or down to meet demand.
- D. High Availability ensures that a system remains operational despite failures.
Confidentiality
Confidentiality is a security principle that ensures sensitive information is protected from unauthorized access, disclosure, or theft.
- Part of the CIA triad (Confidentiality, Integrity, Availability)
- Achieved through encryption, access controls, data masking
- Protects against data breaches and unauthorized viewing
- Critical for privacy and regulatory compliance
Memory trick: CIA: Confidentiality, Integrity, Availability – your security superheroes.
