Sustainable Softworks’ IPNetSentry 1.2 now blocks Code Red-type worms. The company said it’s a first for Macintosh security programs.
The Code Red worm has been circulating on the Internet for a while now — the worm seeks out HTTP servers. Sustainable Softworks said that while Macs aren’t inherently in danger from the Code Red worm itself, attempted intrusions can bog down a user’s Internet connection, eat up bandwidth and fill Web logs with pages of unsuccessful page load attempts.
The new feature in IPNetSentry looks at the contents of packets to detect certain patterns. If it finds a problem, it can then block the originating IP address, thus stopping the intruder in its tracks. Sustainable Softworks claims that the detection mechanism doesn’t affect performance, and features intelligent payload inspection. That way, if a new worm is detected in the future, IPNetSentry can fix the problem.
Sustainable Softworks plans to publish new command lines for IPNetSentry config files as new worm fingerprints become available; the company’s Configuration Web page will feature downloadable updates.
IPNetSentry is US$35. The software can be downloaded from
Sustainable Softworks’ Web site. The upgrade to version 1.2 is free to registered users.
