ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

Usability tests show that 40 % of genuine users fail the image-selection CAPTCHA on your e-commerce sign-up page, causing abandonment. To apply the psychological acceptability principle while still blocking bots, which design change is most appropriate?

  • Eliminate the CAPTCHA entirely and depend solely on IP rate-limiting and account lockout thresholds.

  • Replace the visible image CAPTCHA with a frictionless, behavior-based CAPTCHA that silently scores each request and only issues a challenge when risk is detected.

  • Keep the current CAPTCHA but enforce mandatory SMS-based multi-factor authentication immediately after completion for all new accounts.

  • Increase the number of image categories and require two consecutive successful CAPTCHA completions to strengthen bot resistance.
