What feature prevents unauthorized software execution?

• A. Web Access Control
• B. Program Blocking
• C. Authorized Software
• D. Per-Computer Settings

Answer: (B)

Program Blocking directly stops software from running by enforcing a policy that denies execution of programs that aren’t trusted or aren’t on the approved list. When a program attempts to start, the security engine checks it against the enabled rules (such as allowlists, reputation, or signature checks), and if it doesn’t pass, the launch is blocked. This approach reduces the attack surface by preventing malware, rogue installers, or unapproved apps from executing, even if a user tries to run them or opens a downloaded file. You can configure blocking by factors like file name, path, hash, publisher, or digital signature, and it often works with whitelisting or reputation services. The other options control websites (Web Access Control) or general configuration settings (Per-Computer Settings) or describe lists of allowed software without specifying the active blocking action (Authorized Software), so they don’t address the act of preventing execution as directly as Program Blocking.
