The National Computer Security Survey found that ____% of the businesses sampled experience at least one cybercrime in 2005.

• A. 67%
• B. 60%
• C. 72%
• D. 75%

Answer: (A)

This question tests how to read prevalence data from a security survey. The finding shows that about two-thirds of the businesses sampled experienced at least one cybercrime in 2005, which is 67%. This is the best answer because it directly reflects the survey’s wording: “at least one cybercrime” counts any business with any incident, making 67% the correct proportion of respondents affected. The other numbers would imply different levels of impact and don’t match what the study reported. This result illustrates that cyber threats were widespread even in 2005, underscoring the need for solid security measures, incident response planning, and ongoing cyber risk management.
