Current Version: 1.4.0 (March 9, 2004) / 1.7 (May 29, 2009)

The latest in a long line of network monitoring software from Sustainable Softworks, IPNetSentry is a simple and intelligent security application which protects your Macintosh from outside Internet intruders. This is particularly important for Macintosh users who have cable modem, DSL, or another high-speed Internet service where connections can be maintained and left unattended for hours (or days) at a time. Unlike most other Internet security products, IPNetSentry does not erect barriers for the safe use of your Internet connection. There is no need to "punch holes" in a firewall for specific applications you may wish to run. Instead, IPNetSentry silently and intelligently watches for suspicious behavior, and when triggered, invokes a solid filter which completely bans the potential intruder from your Macintosh.

Version 1.4.0 - the latest version for "Classic" Mac OS - makes the following changes:

• Added payload inspection support for a second version of the SSLammer worm. This worm is a direct attack on TCP Port 443 and can be a problem for Web* and other servers which are running SSL services.

Version 1.7 - the latest version for Mac OS X - adds/changes the following:

• First Run Install: pause after copy phase to allow time for file system to stabilize.
• First Run Install: changed to work the same for non-admin accounts.
• Increase filter table size to 1000 entries.
• ICMP: self repair ICMP server connection if it dies unexpectedly.
• Fixed obscure memory leaks found using Apple's Clang tool.
• Fix checking for idle time to handle equal comparisons correctly.
• Avoid repeated first run install alerts by not trying to install admin only tools when run from non-admin account.
• Fix possible bug in updating Security Log save to disk interval.
• Fix possible timing conflict when replacing and authorizing tools.
• Reorganized demo startup to be more consistent and support paid upgrades.
• Restructure project files to use Subversion based revision control.
• Fix Ethernet bridging to configure promiscous mode correctly.
• Application launch - skip asking for upgrade if there is a valid upgrade key in the pasteboard.
• Upgrade - ask user to authenticate to remove old key if necessary when upgrading, so upgrade will override any previous key even if not writable by the currently logged in user.
• System Requirements are now 10.4 or later.
• Release as version 1.7
