RPZ Bind9 Configuration for DNS Firewalling

This Malware Patrol guide describes how to configure BIND 9 Response Policy Zones (RPZ) to load commercial zone files (mp_rpz_c2, mp_rpz_dga, mp_rpz_malware) that block domains tied to command-and-control servers, DGA-generated domains, and malware hosting. It provides installation notes, configuration snippets for named.conf.* and options, recommendations for cron-based updates and MD5 validation, restart instructions, and operational guidance about potential false positives and enforcement via DHCP/firewall.
