The correct answer is C. Pre-infection . IPS is primarily a pre-infection protection because it is designed to stop exploitation attempts before the target host is compromised. Check Point describes its Threat Prevention solution as a multi-layered defense with both pre-infection and post-infection protections. Within that framework, IPS is the blade that delivers proactive intrusion prevention through signatures, behavioral protections, and preemptive protections, adding protection on top of Firewall enforcement.
This differs from Anti-Bot, which is classically post-infection because it detects infected hosts communicating with command-and-control infrastructure. IPS focuses earlier in the attack chain: reconnaissance, vulnerability exploitation, protocol violations, malicious payload delivery, and attempts to abuse exposed client or server software. It inspects packets and data for risks before successful exploitation results in malware installation, unauthorized access, or control of the system. "Post-inspection" and "pre-inspection" are not the correct lifecycle categories for IPS in Check Point certification terminology. "Post-infection" belongs more naturally to Anti-Bot and compromised-host detection.
