TruSecure awarded certification to three firewalls: ZoneAlarm Pro, Tiny Personal Firewall for Windows 2000, and Norton Personal Firewall for Windows. You can read more about this story at the URL below. http://www.secadministrator.com/articles/index.cfm?articleid=23173 Shortly after we published that story, I received email from a reader who wrote that a group of researchers has discovered a weakness in ZoneAlarm: The firewall might not protect a system against attack under certain circumstances. Users can reproduce the problem, and the firewall-maker, Zone Labs, is aware of the problem. No patch is available yet, but help is on the way I spoke with Zone Labs CEO and founder, Gregor Freund, who says the company expects to make a patch available within the next 2 weeks. Freund said that the company hasn't finished its research yet, so it isn't certain which legacy versions of the firewall the problem affects, but that the current version (2.6.362) is definitely vulnerable. A glitch in multilevel communication is causing the vulnerability. ZoneAlarm uses high-level filtering to govern activity at the application level, and low-level, stateful-inspection filtering to handle activity at the lower layers of the network. The two filtering levels communicate with each other, and a bug in the related code might cause a monitoring oversight. Freund said that Zone Labs hopes to make the patch available before any exploit details become public knowledge. ZoneAlarm users can expect to see a pop-up notice when the patch becomes available. http://www.zonealarm.com Consumers need to be aware that even the most well-intentioned product makers and certification agencies are fallible, and users shouldn't adopt the opinion that these organizations' security solutions are totally secure. We're conducting a new poll this week. If you use a personal firewall, we'd like to know which one? ZoneAlarm, Tiny Personal Firewall, Norton Personal Firewall, Sygate, or another? Please stop by the Security Administrator home page and answer the poll! http://www.secadministrator.com Until next time, have a great week.

Cornell University and AT&T Labs are developing Cyclone, a new computer-programming language similar to C, but which makes introducing bugs into the code much more difficult. The developers claim that Cyclone's data representation and calling conventions are interoperable with C-like programming styles, which will simplify porting code to Cyclone. http://lists.win2000mag.net/cgi-bin3/flo?y=eJIE0CJgSH0BVg0olz0Ac 4. ==== HOT RELEASE (ADVERTISEMENT) ==== * SPONSORED BY VERISIGN -- THE VALUE OF TRUST Secure your servers with 128-bit SSL encryption!

Go to the Security Administrator Channel home page and submit your vote. http://www.secadministrator.com 6. ==== SECURITY TOOLKIT ==== * VIRUS CENTER Panda Software and the Windows 2000 Magazine Network have teamed to bring you the Center for Virus Control. Visit the site often to remain informed about the latest threats to your system security. http://www.secadministrator.com/panda Virus Alert: W32/Badtrans.B Badtrans.B is a worm that spreads rapidly through email by using a file attachment whose name varies randomly. As with W32/Aliz, W32/Badtrans.B exploits a security problem in Internet Explorer (IE) 5.01 and 5.5. The problem in IE lets Microsoft Outlook's preview pane activate the file. When the attachment executes, the worm copies itself to the Windows system directory and attempts to obtain data from the system. Learn more about this worm at the URL below. http://220.127.116.11/panda/index.cfm?fuseaction=virus&virusid=1123 * FAQ: WHY DOES AN EAP-TLS RESUMED SESSION GENERATE ERROR 691? ( contributed by John Savill, http://www.windows2000faq.com ) A. Extensible Authentication Protocol-Transport Layer Security (EAP- TLS) is a Point-to-Point Protocol (PPP) extension supporting additional authentication methods within PPP. TLS provides mutual authentication, integrity-protected cipher-suite negotiation, and key exchange between two endpoints. When you try to reconnect an EAP-TLS connection, the session sometimes stops working and returns error 691 Access was denied because the username and/or password was invalid on the domain. To work around the problem, wait at least 2 minutes before you try to reconnect. Note: If you're using smart cards for remote-access authentication in Windows 2000, you must use the EAP-TLS authentication method. http://www.windows2000faq.com 7. ==== NEW AND IMPROVED ==== (contributed by Scott Firestone, IV, productsat_private) * SECURE PDAS Trust Digital released PDASecure Policy Editor, software that works in conjunction with the company's PDASecure Enterprise security software. You can install PDASecure Policy Editor on a server in a network and install PDASecure Enterprise on each PDA. You can then use the software to push security policies to every PDA device. The software supports Pocket PC, the Palm OS, and PDAs running Microsoft Windows CE. For pricing, contact Trust Digital at 703-246-9198. http://www.trustdigital.com * TEST THE VULNERABILITY OF YOUR EMAIL SYSTEM GFI announced the Email Security Testing Zone, a Web site that lets companies check the vulnerability of their email system. An organization can instantly discover whether its system is secure against current and future email threats, such as email messages containing infected attachments and malformed MIME headers, and HTML email messages with embedded scripts. Users submit their names and email addresses at GFI's Email Security Testing Zone, and GFI sends the users harmless tests to check their email system's vulnerability. Contact GFI at 919-388-3373 or 888-243-4329. http://www.gfi.com 8. ==== HOT THREADS ==== * WINDOWS 2000 MAGAZINE ONLINE FORUMS http://www.win2000mag.net/forums Featured Thread: IE 5.0 Update Files (Six messages in this thread) Chris said he's updating Internet Explorer (IE) 5.0 with Service Pack 2 (SP2) to close holes the Nimda worm exploits. However, he finds that the ie5setup.exe program is only an installer that pulls actual update files from a site on the Internet. This method is slow, and he wonders whether a way exists to download a copy of the entire update to a file or set of files so that he can more easily install it across his network. Can you help?

He also wonders whether System Management Services (SMS) is capable of distributing patches. Can you help?
