AEarly detection reduces cost and risk of breaches
BSecurity testing is only needed before release
CIt slows down development and should be avoided
DOnly developers need to worry about security
Step-by-Step Solution
Solution:
  1. Step 1: Understand benefits of early security testing

    Finding vulnerabilities early prevents costly fixes and reduces breach risks.
  2. Step 2: Compare options for correctness

    Only Early detection reduces cost and risk of breaches correctly states the importance of early security testing.
  3. Final Answer:

    Early detection reduces cost and risk of breaches -> Option A
  4. Quick Check:

    Early security testing = Lower cost and risk [OK]
Quick Trick: Find security issues early to save cost and risk [OK]
Common Mistakes:
MISTAKES
