Presents your XML AND WEB SERVICES E-NEWSLETTER for July 21, 2003 <-------------------------------------------> BUILD BETTER WEB SERVICE USER AUTHENTICATION Some of the secrets of Web services technology are its inherent security risks. That's why developers must be familiar with a variety of techniques to maintain strict control over the Web services they employ. By default, any exposed Web service is available to any technically savvy party that calls it (which is a bit like leaving your server room door open for any passerby to use).User authentication thus becomes of paramount importance; you don't want just anyone taking your carefully developed Web services for a spin. There are two favored and reliable methods for user-authenticated access to exposed Web services: programmatic validation and operating system validation. Neither is perfect, but both offer some assurances against rampant Web service abuse. This article discusses the pros and cons of programmatic and OS-based Web service user authentication. Find out which one might be right for your situation and where each method might still leave you exposed to attack. http://cl.com.com/Click?q=89-h2zbQ-JArajzkI4upwH-p0V9WW8a ----------------------------------------
