Implement switched networks.
Switches forward frames only to the destination port (instead of broadcasting everything like hubs), which prevents attackers from easily capturing traffic on other hosts. This significantly reduces the effectiveness of passive sniffing. (Additional controls: enable port security, use VLANs/802.1X, encrypt traffic and wireless links, and monitor for promiscuous-mode NICs.)
