Despite the CanSecWest exploit (see "Money Meets Mouth on Mac Exploits," 2007-04-23), Macs have proven remarkably secure in comparison with the myriad problems that afflict Windows. But anyone who wants to increase their level of security and knowledge about attacks and vulnerabilities can turn to tools like the DoorStop X Security Suite, from Open Door Networks. It brings together the recently updated DoorStop X Firewall 2.0, Who's There? Firewall Advisor 2.1, and an updated version of the accompanying ebook, "Internet Security for Your Macintosh: A Guide for the Rest of Us." (For what's new, see "Open Door Networks Updates Security Products," 2007-02-05.)
