What measures ensure confidentiality, integrity, and availability of information processed by a computer?

• A. Computer Security
• B. Data Protection
• C. Network Safety
• D. Information Assurance

Answer: (A)

Computer security is fundamental in establishing measures that ensure the confidentiality, integrity, and availability of information processed by a computer. These three principles, often referred to as the CIA triad, form the core objectives of security initiatives.

Confidentiality is supported through various access control mechanisms, ensuring that only authorized users have access to sensitive information. Integrity involves maintaining the accuracy and reliability of data, achieved through controls like hashing and checksums, which help detect any unauthorized changes. Availability ensures that information is accessible to authorized users when needed, which can be supported through redundancy, backups, and protective technologies against failures and attacks.

While other options like data protection, network safety, and information assurance relate to aspects of information security, they do not encompass as broad a range of practices specifically aimed at securing computer systems as computer security does. Data protection primarily focuses on safeguarding personal data and privacy, network safety emphasizes securing communication networks, and information assurance revolves around managing the risks associated with the information throughout its lifecycle. Hence, computer security encapsulates the comprehensive approach necessary to uphold the fundamental principles of information security.
