DoorStop X 2.0, a major new release of the firewall, provided a number of new features which had been requested by our users. It also continued and enhanced the firewall's integration with new versions of two other Open Door products: the Who's There? Firewall Advisor (version 2.1), and our book, Internet Security for Your Macintosh. DoorStop X 2.2 adds Leopard (Mac OS X 10.5) support as well as other minor changes. The three products are available independently or as a suite, the DoorStop X Security Suite.

Enhancements in 2.0

• "Locations." Different sets of protection settings and preferences can be defined and switched to easily, based on the network environment your Mac is in.
• Automated log file archiving. The DoorStop X log file can be saved off and then cleared on a daily, weekly, monthly or yearly basis, or when it gets over a certain size. Requires Mac OS X 10.4.6 or later.
• Service-specific logging. Logging of allowed and/or denied access attempts can now be set on a service-by-service basis.
• Integration with our security blog. The blog can be searched from DoorStop X for the latest information on a service.
• Port lists. Service definitions can now contain arbitrary lists of ports, all of which are protected together.
• Editing of built-in services. Protection information for built-in services, like File and Printer Sharing, can now be edited or removed entirely.
• Allowing of IPv6. DoorStop X disables IPv6 by default, but can be set to allow IPv6 if desired.

DoorStop X 2.2 adds full support for Mac OS X 10.5 (Leopard) including protection options for Leopard's many new and changed networking services. It also includes our Internet security Top 10 list, new service definitions and various bug fixes.

Integration with Who's There? 2.2

From within DoorStop X 2.2, you can invoke Who's There? to display various aspects of the log file:

• Each line of the log file in an easy-to-read format
• A summary of access attempts on a service-by-service basis
• A summary of access attempts by IP address
• A summary of access attempts to a service selected in DoorStop
• A summary of access attempts from an address selected in DoorStop

Switching to Who's There? is as easy as choosing a menu item. And, of course, we've retained DoorStop's previous log functions. DoorStop will also share any custom icons or service names you've added with Who's There, which will use that information to label access attempts.

Integration with Internet Security for Your Macintosh

DoorStop X 2.2 is integrated with the electronic version of our security book Internet Security for Your Macintosh: A Guide for the Rest of Us, 2nd Edition, written by Alan Oppenheimer and Charles Whitaker, both of Open Door Networks. This version has been completely updated for Leopard. DoorStop X 2.2 is also integrated with the book's blog, isfym.com. Integration allows you to:

• Browse the book, section by section
• Have DoorStop display an index of all relevant entries in the book for a particular service
• Search the book's blog and Internet security Top 10 list for relevant entries for a particular service

DoorStop X Security Suite

The DoorStop X firewall is a component of Open Door's DoorStop X Security Suite. The Security Suite is an integrated set of applications that work together to help you protect your Macintosh, while at the same time understanding the details of specific security "events," as well as learning about the overall issues and concepts involved. The key products of the Security Suite include:

• DoorStop X Firewall - This product.
• Who's There? Firewall Advisor - Works with your Macintosh's firewall to help you analyze, understand and respond to access attempts detected by the firewall. Who's There? reads the log file produced by DoorStop X, and then allows you to:
  • view access attempts based on several criteria, including date and risk level
  • analyze access attempts to determine factors like risk level
  • understand issues associated with specific access attempts, as well as broader security concerns
  • summarize accesses by IP address and service type (port number)
  • investigate details of the accessor's IP address, including their network's location and administrator's email address
  • draft an email to the network administrator about the access
• Internet Security for Your Macintosh - Already integrated into the DoorStop X Firewall and the Who's There? Firewall Advisor, Internet Security for Your Macintosh is also available as a standalone product with features that lend themselves to browsing. As described in Accessing Internet Security for Your Macintosh, it is a PDF document with a hot-linked table of contents and index. Being all in one document, you can search the entire document at once for a given term.
• isfym.com - A blog associated with Internet Security for Your Macintosh and Macintosh Internet security in general.
• Internet security top 10 list - a simple, updated list of the top 10 things you can do to protect your Mac on the Internet.
