This is a dual purpose page, covering the standard by the name of WS-Security, as well as security concerns for WebServices.
WebServicesSecurity (WS-Security) has been evolving for a few years and was adopted in Apr2004. See http://www.thestandard.com/article.php?story=20040409040946753
WebServicesSecurity (WS-Security) is a higher level ExtensibleMarkupLanguage stack, and it will break if lower level protocols such as SimpleObjectAccessProtocol uses extensions that do not conform to requirements of ExtensibleMarkupLanguage (e.g. when DirectInternetMessageEncapulation? is used for opaque data transmission).
See a Apr03 writeup of a 2002 consultancy performed by IBM at http://www-128.ibm.com/developerworks/webservices/library/ws-security.html
Security concerns for WebServices

Standardization efforts
Big guns back web services standards
In Jul05 Oracle joined MS and IBM to back the WS-Trust, WS-SecureConversation, and WS-SecurityPolicy? trough the OasisOrganization. However WebServicesFederation? is not included in this arrangement. See http://www.vnunet.com/articles/print/2140082 "This is too bad. See below"
OASIS, in Aug04, approved draft for review of SecurityAssertionMarkupLanguage (SAML), which is a protocol to be used by another OASIS offering, WebServicesSecurity. See http://www.xmlmania.com/news_article_1451-OASIS-Security-Services-TC-Releases-Approved-SAML-2.0-Committee-Drafts-for-Review.php
Implementation aspects
In Ref A above, one company uses two-way SecureSocketsLayer connections, and another uses XML security gateways for multiple partners

No clear winner in .NET/J2EE security race
Secure web servers are the equivalent of heavy armored cars. The problem is, they are being used to transfer rolls of coins and checks written in crayon by people on park benches to merchants doing business in cardboard boxes from beneath highway bridges. Further, the roads are subject to random detours, anyone with a screwdriver can control the traffic lights, and there are no police. -- Eugene SpaffordThat's great stuff. Looking for you to further enhance your analogy later. More seriously, can you create a HomePage here so I can beg and nag you for comments on SecurityForTheInsecureAndUnsure? My Yahoomail account is dl UNDERSCORE australia and I hope to hear from you. Cheers from David -- dl DeleteWhenRead
