SAML uses XML to enable new Web-based security functions that interoperate across different Web sites, which will help create federated networks. http://www.oasis-open.org/committees/security In April 2002, Microsoft, IBM, and VeriSign announced Web Services Security (WS-Security), and in the June 12, 2002, Security UPDATE commentary, I discussed WS-Security to some extent (see the first URL below). The specification will support many types of credential information, including Kerberos, public key infrastructure (PKI), Extensible Rights Markup Language (XrML), SAML, and Secure Sockets Layer (SSL)/Transport Layer Security (TLS). Sun Microsystems also announced Liberty Alliance, its effort to help develop federated network technology. http://www.secadministrator.com/articles/index.cfm?articleid=25593 http://www.ws-i.org According to James Kobielus, senior analyst at Burton Group, "SAML 1.0 supports secure interchange of authentication and authorization information by leveraging the core Web services standards of Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), and Transport Layer Security (TLS). Most vendors of Web access management solutions have committed to SAML 1.0 and are currently implementing the specification in their products." http://www.oasis-open.org/news/oasis_news_11_06_02.shtml Joe Pato of Hewlett-Packard (HP), co-chair of the OASIS Security Services Technical Committee, said that a major SAML design goal was single sign-on (SSO) capabilities, which would let users authenticate in one domain and access resources in another domain. SAML 1.0 includes that capability. In addition, according to Pato, "Several profiles of SAML are currently being defined that support different styles of SSO and the securing of SOAP payloads." If you're completely unfamiliar with WS-Security, read Christa Anderson's summary of the technology, which helps explain what it is and what it can do. You'll find her article, "WS-Security Sets Standard for Web Services Transactions" at the URL below. http://www.secadministrator.com/articles/index.cfm?articleid=24401 If you're a Web developer or you administer Web server security, you might be interested in reading about SAML assertions and protocols. The document you'll find at the first URL below outlines the syntax and semantics. Another specification document can help you obtain a better understanding of how SAML works with WS-Security. That document (see the second URL below) describes how to use WS-Security headers to securely add SAML assertions. http://www.oasis-open.org/committees/security/docs/cs-sstc-core-01.pdf http://www.oasis-open.org/committees/security/docs/draft-sstc-ws-sec-profile-04.pdf But there's a catch regarding Microsoft's implementation of SAML. In July, "Network World Fusion" (see the first URL below) reported that Microsoft is implementing SAML 1.0, but only to a limited extent. In the article, Kobielus said, "[Microsoft is] not implementing the full suite of SAML assertions and profiles the way others are ... At some point you have to ask what is the purpose, if Microsoft is going to do it their own way." The article points out that Microsoft used the same tactic when the company implemented Kerberos in Windows 2000. To learn more about how Microsoft implements SAML, be sure to read the related Microsoft document, "WS-Security Profile for XML-based Tokens," on the Microsoft Web site (see the second URL below). http://www.nwfusion.com/news/2002/0716msla.html http://msdn.microsoft.com/library/en-us/dnglobspec/html/ws-security-xml-tokens.asp According to OASIS, Baltimore Technologies, BEA Systems, Computer Associates (CA), Entrust, HP, Hitachi, IBM, Netegrity, Oblix, OpenNetwork, Quadrasis, RSA Security, Sun, VeriSign, and other members of the OASIS Security Services Technical Committee developed the SAML OASIS Open Standard. Many vendors support SAML, and some of you might have begun using the technology before its official approval. Please participate in our Instant Poll this week and tell us whether you use SAML or some other credential technology for your Web applications. ~~~~~~~~~~~~~~~~~~~~ ~~~~ SPONSOR: TIPS & TRICKS WEB SUMMIT ~~~~ ATTEND OUR FREE TIPS & TRICKS WEB SUMMIT Join us on December 19th for our Tips & Tricks Web Summit featuring three eye-opening events: Disaster Recovery Tips & Tricks, Intrusion Detection: Win2K Security Log Secrets, and Merging Exchange Systems: Tips for Managing 5 Key Challenges.

This vulnerability stems from a buffer-overflow condition in the iSQL application. The vendor, Oracle, has released Security Alert #46 to address this vulnerability and recommends that affected users apply the appropriate patch mentioned in Oracle's alert. http://www.secadministrator.com/articles/index.cfm?articleid=27240 * DoS IN MICROSOFT WINDOWS XP AND WIN2K PPTP A Denial of Service (DoS) vulnerability exists in Windows XP and Windows 2000 PPTP. This DoS vulnerability results from an unchecked buffer in a section of code that processes the control data used to establish, maintain, and tear down PPTP connections. The vendor, Microsoft, has released Security Bulletin MS02-063 (Unchecked Buffer in PPTP Implementation Could Enable Denial of Service Attacks) to address this vulnerability and recommends that affected users apply the appropriate patch mentioned in the bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=27227 * MULTIPLE VULNERABILITIES IN MICROSOFT IIS 5.1, 5.0, AND 4.0 Four new vulnerabilities exist in Microsoft IIS. The most serious problem lets an attacker escalate privileges. Another problem results in a Denial of Service (DoS) condition on the vulnerable server. The vendor, Microsoft, has released Security Bulletin MS02-062 (Cumulative Patch for Internet Information Service) to address these vulnerabilities and recommends that affected users apply the appropriate patch mentioned in the bulletin. This patch is cumulative and addresses all previously discovered vulnerabilities. http://www.secadministrator.com/articles/index.cfm?articleid=27228 3. ==== ANNOUNCEMENTS ==== (brought to you by Windows & .NET Magazine and its partners) * HOW CAN YOU RECLAIM 30% TO 50% OF WINDOWS SERVER SPACE?

EventComb is a new free tool from Microsoft that lets you search event logs for specific information. EventComb is part of a Microsoft document called "Security Operations Guide for Windows 2000 Server." To obtain EventComb, you need to go to Microsoft's Web site (the URL is linked in this article) and download secops.exe. When you run secops.exe, the program creates a folder called SecurityOps. Within SecurityOps is a folder named EventComb, which contains a compiled HTML Help file and the EventComb program. http://www.secadministrator.com/articles/index.cfm?articleid=27132 * NEWS: FIRE & WATER TOOLKIT BETA AVAILABLE NTObjectives (NTO) announced that its new Fire & Water Toolkit is now available for public beta. The toolkit is an assessment and defense tool that you can use on local and remote networks. NTO said, "Fire & Water is a collection of cohesive, interactive command-line tools that perform network discovery, mapping, assessment, and reporting, as well as robust Web server defense." By using XML output interactively, Fire & Water can effectively manage multiple scans and their resulting output through standard output in the command line, Comma Separated Value (CSV), and HTML reports (created through Extensible Style Language--XSL templates provided with the tools) or through custom report formats. http://www.secadministrator.com/articles/index.cfm?articleid=27273 5. ==== HOT RELEASES (ADVERTISEMENTS) ==== * FOCUS YOUR IT RESOURCES Learn how better infrastructure management practices can speed the integration of e-business enterprises, while providing assurance of continuous availability, flexibility and scalability.
