FSF sysadmins use reactive tactics to block botnets

The FSF’s system administrators are focusing on botnet mitigation. They employ reactive techniques to identify malicious traffic. When a botnet is detected, they trigger blocking rules. The approach aims to cut off command‑and‑control communications. It leverages existing infrastructure without new hardware. The strategy reduces the impact of compromised hosts. FSF reports that the method has lowered botnet prevalence. Future plans include refining detection and response automation.
