CompTIA CySA+ (CS0-003) — Question 233

Which of the following characteristics ensures the security of an automated information system is the most effective and economical?

Answer options

• A. Originally designed to provide necessary security
• B. Subjected to intense security testing
• C. Customized to meet specific security threats
• D. Optimized prior to the addition of security

Correct answer: A

Explanation

The correct answer is A because a system that is originally designed with security in mind integrates necessary protections from the start, which is often more effective and economical. Options B and C, while important, focus on testing and customization after the fact, which can be more costly and less efficient. Option D suggests optimization before security is added, which may leave vulnerabilities unaddressed.
