Web Services Security (Application Development)

Signing and signature verification can be done using asymmetric or symmetric keys.

Signature ensures non-repudiation of the signing entity and proves that messages have not been altered since they were signed. In addition, WS-Security provides profiles for 5 security tokens: Username with password digest , X.

Web Service Security Cheat Sheet

The SOAP envelope body includes the business payload, for example a purchase order, a financial document, or simply a call to another Web service. SAML is one of the most interesting security tokens because it supports both authentication and authorization. SAML includes 3 parts:. The full SAML specification is used in browser-based federation cases. The SAML security token is particularly relevant in situations where identity propagation is essential.

The use of transport security to protect the communication channel between the Web service consumer and Web service provider. Message-level security to ensure confidentiality by digitally encrypting message parts; integrity using digital signatures; and authentication by requiring username, X. Oracle Web Services Manager WSM is designed to define and implement Web services security in heterogeneous environments, including authentication, authorization, message encryption and decryption, signature generation and validation, and identity propagation across multiple Web services used to complete a single transaction.

How Oracle Fusion Middleware Secures Web Services and Clients

Figure shows an Oracle Fusion Middleware application that demonstrates some common interactions between Web services and their clients. How security is managed at each step in the process is explained following the figure. As shown in the previous figure, there are two types of policies that can be attached to Web services: The following describes in more detail the Web service and client interactions called out in the previous figure, and how security is managed at each step in the process. Policies that are attached to WebLogic Web services at design time cannot be detached at deployment time.

You can only attach new policies. At the Web service client side, Oracle WSM intercepts the SOAP message request to the service, injects the relevant tokens, and signs and encrypts the message, as required by the attached policies. At the Web service side, Oracle WSM intercepts the SOAP message request to the service, extracts the tokens, and verifies the client's credentials against an identity management infrastructure for example, a file, an LDAP-compliant directory, or Oracle Access Manager , as required by the attached policies.

Again, at the Web service client side, Oracle WSM intercepts the SOAP message request to the service, injects the relevant tokens, and signs and encrypts the message, as required by the attached policies. In this case, components in a larger composite application interact with the WebLogic Web service. Configure policy sets through metadata exchange WS-MetadataExchange.

Securing JAX-WS web services using message-level security

For web application assessment, the ISO uses Quayls, an automated web application and web services vulnerability assessment tool that is specifically designed to assess potential security flaws and to provide all the information needed to fix them. As an assessment is initiated, Quayls assigns "assessment agents" that dynamically catalog all areas of a Web application. As these agents complete the assessment, findings are reported to a main security engine that analyzes the results. Quayls then launches audit engines to evaluate the gathered information and apply attack algorithms to locate vulnerabilities and determine their severity.

Manual assessment using Quayls is also possible for in-depth testing. Reporting is provided in the mail GUI console and as stand alone reports in numerous formats. These references provide general guidance to the technologies addressed in these sections and the specific recommendations contained therein. This section addresses authentication issues, ensuring a user has the appropriate privileges to view a resource.

Topics such as principle of least privilege, client-side authorization tokens, etc. This section addresses topics such as authenticated users having a robust and cryptographically secure association with their session, applications enforcing authorization checks and applications avoiding or preventing common web attacks, such as replay, request forging and man-in-the-middle. This section deals with applications being robust against all forms of input data, whether obtained from the user, infrastructure, external entities or databases.

This section addresses application issues so they are secure from well-known parameter manipulation attacks against common interpreters. This section addresses issues that help to ensure the application is robust when subjected to encoded, internationalized and Unicode input. This section deals with designing well-written applications that have dual-purpose logs and activity traces for audit and monitoring. This makes it easy to track a transaction without excessive effort or access to the system.
