A new tool from domain name lookup service OpenDNS secures your Mac’s connection to the firm’s servers when translating a human-readable name into its IP address, as Glenn Fleishman explains at Macworld. This prevents a host of malicious activities that can occur when third parties tamper or poison the values returned for a DNS request. It’s free, and it works with OpenDNS’s free and paid offerings. follow link

New Tool Secures Against DNS Poisoning
When I tried to use this (with OpenDNS 3.0 on my Mac Mini and OSX 10.6.8) it reported it wouldn't work with an Intel Mac!
It's a 64-bit app, so it won't work with every Intel system. But it should give a more sensible error!
Works fine on my MacBook Pro 2.4 GHz as well as on my iMac 3.06 GHz as well as on my Mac Mini 2 GHz, all three Intel Core 2 Duo and all three on OSX 10.6.8.
Its About states: "The service is not configured to maintain state between reboots, it will default to off. That is only for early releases. Eventually we will have it maintain state between reboots."
Today's update to version 0.9 has settings that are "persistent across reboots".
