What is the primary goal of computer security?

• A. To protect against unauthorized access
• B. To ensure data integrity and confidentiality
• C. To maintain both availability and integrity of systems
• D. All of the above

Answer: (D)

The primary goal of computer security encompasses multiple aspects that are essential for protecting information systems and data. The option stating "All of the above" reflects that effective computer security aims to address unauthorized access, ensure data integrity and confidentiality, and maintain system availability and integrity.

Firstly, protecting against unauthorized access is crucial because it helps safeguard sensitive information from individuals who should not have access. This protection is foundational to establishing a secure environment.

Secondly, ensuring data integrity and confidentiality is vital for maintaining trust in data management. Data integrity ensures that information remains accurate and unaltered, while confidentiality guarantees that sensitive data is only accessible to authorized users. Both elements are key components of a comprehensive security strategy.

Lastly, maintaining the availability and integrity of systems is essential for operational continuity. Availability ensures that authorized users can access systems and information when needed, while integrity relates to guarding against modifications or disruptions that could compromise the system's reliability.

By collectively addressing these objectives, computer security forms a robust framework that protects systems and data against a wide variety of threats, thus making "All of the above" the most encompassing and accurate response.
