"In a perfect world we never worry about backups because computers never have problems. As we all know that is not the case. Backups are very important to keep operational. DCS Netlink is an Internet and Network service provider offering many services and using backup software such as UltraBac is a very essential part of our operation", says Netlink's Backup Administrator Steven Gibbons. "Just recently our mail server, which provides hundreds of mail accounts, went down. We were able to completely rebuild and get the mail server up and running within two hours without losing any mail."

Sincerely, Mark Joseph Edwards, News Editor (mark () ntsecurity net) 2. ========== SECURITY RISKS ========= (contributed by Mark Joseph Edwards, mark () ntsecurity net) * IE ALLOWS SPOOFING OF TRUSTED WEB SITES Two newly discovered vulnerabilities in Microsoft Internet Explorer (IE) 5.01 and 5.5 let an attacker spoof trusted Web sites. The first vulnerability involves how IE validates digital certificates sent from Web servers. The second vulnerability can let a Web page display the URL from a different Web site in the IE address bar. Microsoft has released a patch and FAQ and will make article Q295106 available online soon. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=21178 * NETSCAPE ENTERPRISE SERVER ALLOWS REMOTE COMMAND EXECUTION A vulnerability in the Netscape Enterprise Server 4.1 for Windows NT Web Publisher can give an attacker system-level shell access on the server. By sending a large buffer containing executable code and a new instruction pointer, an attacker can gain remote system-level shell access to the vulnerable server. The vendor, iPlanet, acknowledges this vulnerability and has released a patch. iPlanet further recommends that users apply Service Pack 8 (SP8) when iPlanet makes it available. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=21179 * IIS MIGHT ALLOW REMOTE COMMAND EXECUTION Nsfocus discovered three vulnerabilities in Microsoft's IIS 4.0 and 5.0 that can lead to a Denial of Service (DoS) attack, remote code execution, and information disclosure. Microsoft has released an FAQ, patch, and articles Q293826, Q295534, Q294370, and Q288855 to address these matters. http://www.windowsitsecurity.com/articles/index.cfm?articleID=21101 * CARELLO E-COMMERCE SERVER ALLOWS REMOTE COMMAND EXECUTION Peter Grundl discovered that a vulnerability in Carello E-Commerce Server 1.2.1 for Windows NT lets an attacker use the System Security context to run programs located on the server. The carello.dll uses full physical paths to execute its scripts instead of paths relative to the Web root. Then vendor has released version 1.3, which corrects this problem. http://www.windowsitsecurity.com/articles/index.cfm?articleID=21102 3. ==== ANNOUNCEMENTS ==== * WE'RE WATCHING OUT FOR YOU!

You'll find eye-opening articles, white papers, a technical forum, and much more! http://www.win2000mag.net/channels/storage 4. ==== SECURITY ROUNDUP ==== * NEWS: NEW WORM PURPORTS TO BE EMAIL FROM SYMANTEC A new worm, called Hard.A, has been discovered that arrives in a spoofed email and appears to be a message from Symantec, a leading antivirus software vendor. The message subject reads "Symantec Anti-Virus Warning," and the message itself contains a file attachment (www.symantec.com.vbs) that, among other things, triggers the worm each November 24. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=21081 * NEWS: VISA MAKES E-COMMERCE SAFER WITH PASSWORDS AND SMART CARDS Visa International is offering its new Payer Authentication Service (PAS) to banks as a way to curb e-commerce-related fraud. By using a realtime password authentication mechanism, PAS helps banks verify a card user's identity more effectively. Arcot Systems announced its support for PAS, which is based on Arcot's TransFort product. TransFort authenticates and digitally signs transactions in realtime to provide nonrepudiation of online transactions. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=21122 * REVIEW: SYGATE ENTERPRISE NETWORK Personal firewalls are becoming more commonplace in enterprise networks. However, ensuring quality centralized management for these firewalls is a challenge when you roll out such technology. Sygate Technologies' Sygate Enterprise Network is an admirable solution: a centrally managed distributed personal firewall product that you can integrate with and scale to a network of almost any size. Read all about it in the review on our Web site. http://www.win2000mag.com/Articles/Index.cfm?ArticleID=20391 * EDITORIAL: WHERE THE REAL MONOPOLY IS Microsoft Office XP aptly demonstrates what we knew all along: The Department of Justice (DOJ) was wrong in prosecuting Microsoft over its browser; the company's real monopoly is in Office. Office XP embraces two of the most user-unfriendly concepts the industry has seen since Lotus attempted to add copy protection to Lotus 1-2-3: a subscription-based licensing option and forced registration. http://www.win2000mag.com/Articles/Index.cfm?ArticleID=20711 5. ==== HOT RELEASE (ADVERTISEMENT) ===== * MICROSOFT ISA SERVER 2000 ICSA Labs-certified, ISA Server provides packet/circuit/ application-layer filtering, integrated intrusion detection, stateful inspection, and granular, policy-based access control. Integration with Windows 2000 VPN, QoS, and Active Directory makes secure, enterprise-class Internet connectivity easy-to-manage.

Visit the site often to remain informed about the latest threats to your system security. http://www.windowsitsecurity.com/panda * FAQ: WHY CAN'T I CREATE A KERBEROS-BASED TRUST BETWEEN TWO DOMAINS IN DIFFERENT FORESTS? ( contributed by http://www.windows2000faq.com ) When you manually create trusts, you can select one of two authentication protocols. Kerberos V5 authentication protocol is the default authentication service for Windows 2000. You use Kerberos V5 to verify the identity of a user or host. This protocol is used for trusts between domains in a tree and between the root domains in a forest. The NT LAN Manager (NTLM) authentication protocol is the default for network authentication in Windows NT 4.0 and earlier; Win2K supports NTLM, but not as the default. NTLM is a challenge/response authentication protocol. A transitive Kerberos-based trust links domains within a forest. Thus, when you create a trust between two domains in different forests, you can select only NTLM because Kerberos isn't available for cross-forest trust relationships. This limitation isn't a Kerberos one, but a limitation of the Microsoft implementation. If you use a third-party Kerberos implementation (e.g., MIT), you can use Kerberos for cross-forest trusts. * SOHO SECURITY: GOOD THINGS COME IN SMALL PACKAGES After reviewing and testing a computer product, Jonathan Hassel often can't say that he would use the product in his own small office/home office (SOHO). Not many products show clear innovation, are designed with the end-user in mind, or offer seamless compatibility with other products. However, the Linksys Instant Broadband Cable/DSL Router series is one of the few exceptions. Learn all about it in Jonathan's latest column on our Web site. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=21053 7. ==== NEW AND IMPROVED ==== (contributed by Judy Drennen, products () win2000mag com) * FINGERPRINT RECOGNITION FOR COMPUTER SYSTEMS Guardware Systems released a biosensor that has been patented for use in the United States. Biosensor recognizes and rejects finger surrogates with which intruders might try to compromise a system. Fingerprint recognition is an effective and secure alternative to passwords for access to computer systems and data because each fingerprint is unique. Reliable living finger detection is a crucial feature of a high-end fingerprint recognition system. For more information, go to Guardware Systems' Web site. http://www.guardwaresystems.com * INTEROPERABLE AND SCALABLE SECURITY SOLUTIONS Aladdin Knowledge Systems announced eSafe Gateway 3.02 and eSafe Mail solutions. eSafe Gateway 3.02 offers OPSEC compatibility with the addition of built-in CVP interface. eSafe Mail is a scalable content security application that provides a clean flow of email, safe from vandals, viruses, Trojans, worms, scripts, and other malicious content. eSafe Mail can operate as a standalone SMTP mail relay, or you can install it on Exchange 2000 and 5.5 mail servers. Information about these solutions is available on Aladdin's Web site. http://www.ealaddin.com/esafe/ 8. ==== FEATURED THREAD ==== * WINDOWS 2000 MAGAZINE ONLINE FORUMS http://www.win2000mag.net/forums * FEATURED THREAD: DISABLE ACCESS DEPENDING ON THE IP ADDRESS Hubert Ming wants to know how to deny access to his Windows 2000 domain controller (DC) to all IP addresses outside the subnet of his DC.
