NIST Guide to Secure Web Services
The National Institute of Standards and Technology has released a 128-page guide to securing web services. It discusses trust relationships, secure service-to-service exchanges, and threats such as denial-of-service attacks. It also covers current and emerging standards, such as SAML, XACML and WS-Trust.

Trusted Identity for Web Services
Patrick Harding discusses user identity authentication using Security Assertions Markup Language (SAML), Web Services Security (WSS) and Web Services Trust (WS-Trust).

Mark Colan, Jeff Carmichael, Rajiv Gupta, Thor Larholm and Gene Thurston discuss web services security in video interviews and presentations at the SDSIC Web Services conference at the San Diego Supercomputer Center.

 

Articles, Papers, Specifications

A Guide to Building Secure Web Applications
This is a guide developed by the Open Web Application Security Project.

An Overview of Security in the .NET Framework
Dr. Demien Watkins (Project 42), Sebastian Lange (Microsoft)

This white paper describes the .NET role-based security model and its primary abstractions (Principals and Identity). .NET Framework provides code access security (evidence-based security).

An Overview of Virus Activity in 2003
This is an informative summary by Kaspersky Labs of viruses, worms and security problems during 2003. It also discusses future concerns such as Trojan programs and retroviruses.

J2EE and Web Services Security
Pankaj Kumar

This is Chapter 11 of J2EE Security for Servlet, EJBs, and Web Services. It discusses security when developing Web services with Java, including servlet security, SSL, Axis, and WSSec-compliant messages.

.NET Security
"What about security?" seems to pop up in almost every conversation about Web services. This article discusses the security architecture of Microsoft's .NET framework.

Oracle SSL Update for CERT CA200326 and older SSL issues
This is an Oracle update about Open SSL vulnerabilities.

OVAL XML Specification Released
The final draft of the OVAL XML Specification is now available. Mitre is promoting OVAL as a standard for characterizing system vulnerabilities.

Packet Sniffing
Steve Gibson explains network monitoring using a sniffer.

Securing Web Services - Concepts, Standards and Requirements
This Sun Microsystems white paper explains issues related to securing web services from internal and external threats. 

Security in a Web Services World: A Proposed Architecture and Roadmap
This white paper presents a proposed web services security architecture from IBM and Microsoft. It layers web services security over SSL and IP security, and uses technologies such as XML encryption, X.509 certificates and Kerberos tickets.

Serious Flaw in Linux
This article describes a vulnerability that gives users unlimited access privileges to a computer running Linux.

SOAP Security Issues
Bruce Schneier discusses the risks of using SOAP, such as passing commands through firewalls.

Strong Names and Security in the .NET Framework
Keith Brown (DevelopMentor)

Strong names are a successor to Windows Globally Unique Identifiers (GUID). To generate unique assembly names, .NET CLR multiplies two large random prime numbers to produce a 1024-bit RSA public key.

Web Services Security Kerberos Binding
This document describes how to use Kerberos security with web services security specifications. This is a draft document from IBM and Microsoft.

Web Services Policy Framework (WS-Policy)
WS-Policy provides a grammar for expressing properties of entities as policies. A policy is a collection of policy assertions. The WS-Policy expression defines XML-based structures called policy expressions and a core grammar for expressing how policy assertions apply.

Web Services Secure Conversation Language 
This WS-SecureConversation specification defines mechanisms for establishing a security context, sharing contexts, and deriving session keys from contexts. The A <SecurityContextToken> security token represents a security context that can be embedded in the  <Security> header block of a SOAP message header.

Web Services Security (WS-Security)
This document explains key solutions for Web services security.

Web Services Security Kerberos Binding
This document describes how to use Kerberos security with web services security specifications. This is a draft document from IBM and Microsoft.

Web Services Security SOAP Message Security
This document SOAP enhancements to provide message integrity, message confidentiality, and single message authentication. WS-Security provides a solution for associating X.509 certificates, Kerberos tickets, and opaque encrypted keys with messages.

WebSphere and J2EE Security
This IBM Red Book is not specifically about Web services, but it discusses security with a leading platform for Web services (IBM WebSphere).

WS-I Security Profile
This is a draft of the Basic Security Profile Security Scenarios from the Web Services Interoperability Organization (WS-I). This document describes Web services security challenges, threats and countermeasures.

XACML 1.0
The OASIS eXtensible Access Control Markup Language (XACML) is an XML  vocabulary for expressing authorization policies against objects that are themselves identified in XML.

 

Encryption, Digital Signatures

Decryption Transform for XML Signature
This document by the XML Encryption Working Group suggests a method for verifying digital signatures in encrypted XML documents.

Digital Signatures
Ed Simon, Paul Madsen, Carlisle Adams

This article is an excellent starting point for developers whose applications require secure XML document processing.

Introduction to XML encryption and XML signature
Murdoch Mactaggart

Helpful overview of XML digital signatures, encryption and other XML-related security resources.

Key Management Specification (XKMS)
Exchanging human-readable documents presents security challenges. Solutions for secure XML processing includes digital signatures and encryption. XKMS defines protocols for public key handling. X-KISS describes a protocol for a trust service. X-KRSS describes a web service protocol for registering public keys.

XML-Digital Signatures (DSIG)
This is a IETF/W3C specification for digitally signing XML documents.

XML Encryption Syntax and Processing
This W3C spec defines a process for encrypting data and producing a result in XML. The data may be an XML element, document or arbitrary data.

 

Sites
