DoorStop 1.0 Released -- Open Door Networks has released DoorStop 1.0, a software-based firewall that promises to improve security on Macintosh-based Internet servers, particularly those providing AppleShare-over-IP services via Open Door's ShareWay IP. Operating only on the Macintosh on which it is installed, DoorStop enables you to block or grant access to specific TCP services - see "Open Door Slams Network Doors" in TidBITS-444 for more details. DoorStop requires a PowerPC-based Macintosh, Mac OS 8.1, and Open Transport 1.3 or later. Single copies of DoorStop cost $299 or $199 for education customers; other volume and site licenses are available. You can download a 680K evaluation version. [ACE]
