Certified Network Defender (CND) — Question 130

Which of the following helps prevent executing untrusted or untested programs or code from untrusted or unverified third-parties?

Answer options

• A. Application sandboxing
• B. Deployment of WAFS
• C. Application whitelisting
• D. Application blacklisting

Correct answer: A

Explanation

The correct answer is Application sandboxing, as it creates isolated environments for running untested applications, limiting their access to system resources and protecting the host system. Application whitelisting allows only approved applications, which is different from sandboxing, and application blacklisting blocks known harmful applications, but does not prevent the execution of untested code. Deployment of WAFS (Web Application Firewalls) is focused on protecting web applications rather than executing local programs.
