During which installation process is the IPS policy for pre-R80 gateways installed?

The installation of the IPS policy for pre-R80 gateways occurs during the Threat Prevention policy installation. This is because the Threat Prevention policy encompasses multiple security functionalities, including Intrusion Prevention System (IPS), URL Filtering, Anti-Bot, and Antivirus. For gateways that are prior to the R80 version, the IPS functionality is specifically included as part of the Threat Prevention suite, meaning that when you install the Threat Prevention policy, you are also effectively deploying the IPS policy.

In contrast, firewall policy installations primarily focus on access control and rules defining allowed or denied traffic but do not encompass IPS specifics. Other policy options like Anti-bot and Access Control policies are focused on particular areas and do not integrate IPS features independently of the Threat Prevention policy. Thus, the correct answer highlights the comprehensive nature of the Threat Prevention policy installation in handling various security mechanisms in earlier versions of the Check Point software.
