With all the recent fuss about security on the Mac, it's worth pointing out that we have plenty of tools to protect us from the most common Internet dangers. Open Door Networks recently updated all its Internet security products, which are available separately or as a bundle. DoorStop X Firewall 2.0 adds Location Sets, which enable you to specify different protection settings for different environments (for instance, you might want more stringent firewall settings when using public hotspots than when you're at home behind your NAT gateway). Other new features include automated log archiving and service-specific logging options. Who's There? Firewall Advisor 2.1, which provides additional information about attacks and attackers, adds new filtering and searching features, enhanced real-time scrolling, and new service definitions.

And lastly, Open Door has updated their ebook, "Internet Security for Your Macintosh: A Guide for the Rest of Us," to discuss the latest issues in Internet security for Mac users, most notably topics related to running Windows on Intel-based Macs. The ebook itself, and Open Door's security blog, have also been integrated into all of the products, so you can search the blog for related items directly from within DoorStop X or Who's There. Through 14-Feb-07, DoorStop X Firewall costs $40 (upgrades are $30), Who's There? Firewall Adviser costs $30 (upgrades are $20), the ebook costs $10 (free upgrades), and the DoorStop X Security Suite bundle of all the products is priced at $70 (with $40 upgrades).
