Fill in the blank: The IPS policy for pre-R80 gateways is installed during the _______.

The correct answer is that the IPS policy for pre-R80 gateways is installed during the Threat Prevention policy install. This is due to the way security policies are structured in Check Point systems prior to the R80 version. In these earlier versions, the Threat Prevention policy encompasses various security mechanisms, including Intrusion Prevention System (IPS), Anti-Bot, and Application Control.

During a Threat Prevention policy installation, the IPS settings become an integral part of the overall approach to preventing threats, thereby ensuring that all necessary protections are applied to the gateway. This process allows for comprehensive threat mitigation strategies to be deployed in one action rather than needing to install different policies piecemeal.

This cohesive framework contrasts with the other policy options, which focus on specific aspects of security (like Access Control) and do not encompass the broader set of threat prevention functions that including IPS.
