Which CIA triad component ensures that data has not been altered without authorization?
Answer: Integrity
Integrity ensures data remains accurate and unmodified by unauthorized parties.
A company's web server crashes and customers cannot access the online store. Which CIA principle is violated?
Answer: Availability
Availability ensures systems are accessible when needed. A server crash preventing access violates this.
Which security control best protects the confidentiality of data transmitted over a public network?
Answer: Encryption
Encryption makes data unreadable without the proper key, providing primary confidentiality protection during transmission.
What is the purpose of access control lists (ACLs) in relation to the CIA triad?
Answer: They support confidentiality and integrity by restricting who can view or modify resources
ACLs support confidentiality (restricting who views data) and integrity (restricting who modifies data).
Which approach provides defense in depth for CIA triad protections?
Answer: Implementing multiple layers of security controls addressing confidentiality, integrity, and availability
Defense in depth uses multiple overlapping layers so if one fails, others still provide protection.
What role does multi-factor authentication (MFA) play in supporting the CIA triad?
Answer: It supports confidentiality by ensuring only verified users access protected resources
MFA strengthens confidentiality by requiring multiple verification factors to access information.
