What prevents unauthorized code execution in applications?

• A. Code Injection Protection
• B. Code Injection
• C. Block Mode
• D. BlueKeep

Answer: (A)

Preventing unauthorized code execution in applications hinges on protecting against code injection. Code injection protection targets the exact way attackers try to run their own code by feeding crafted input into an app. By validating and sanitizing inputs, using parameterized queries and safe APIs, encoding outputs, and enforcing least-privilege execution and proper sandboxing, the application becomes resistant to injected payloads being treated as executable instructions. In contrast, code injection describes the attack itself—what the attacker does to try to run code—while block mode is a cryptographic technique unrelated to controlling code execution, and BlueKeep is a Windows vulnerability that could enable code execution if exploited. Patching, hardening, and applying these protections together best prevent such unauthorized execution.
