Advanced Threat Protection defends users from malicious active content, phishing, exploit behavior, C2 callbacks, and risky web destinations. It works as part of ZIA ' s inline security stack, often alongside TLS inspection, Cloud Sandbox, DNS security, IPS, and URL categorization. Option C (Malicious active content) is correct because malicious active content is the security object ATP is designed to detect and block.
Why the other options are incorrect:
A. Vulnerable JavaScripts: Vulnerable JavaScript describes risky script behavior or client-side code, but it is narrower than the full ATP active-content category.
B. Large iFrames: An iFrame is an embedded page frame; suspicious iFrames can be a signal, but size alone is not the ATP protection category.
D. Command injection attacks: Command injection targets an application or server by passing operating-system commands through vulnerable input fields.
