The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies.
Data security typically goes one step further than database security and applies control directly to the data element. This is often referred to as data-centric security. On traditional relational databases, ABAC policies can control access to data at the table, column, field, cell and sub-cell using logical controls with filtering conditions ...
The XML processor then replaces occurrences of the named external entity with the contents that is referenced by the system identifier. If the system identifier contains tainted data and the XML processor dereferences this tainted data, the XML processor may disclose confidential information normally not accessible by the application.
Web API security entails authenticating programs or users who are invoking a web API. Along with the ease of API integrations come the difficulties of ensuring proper authentication (AuthN) and authorization (AuthZ). In a multitenant environment, security controls based on proper AuthN and AuthZ can help ensure that API access is limited to ...
Messages with a specific content may be routed differently. For example, some messages may have different priority or security policies. Policy: Enterprise messaging systems should provide some consideration for a centralized policy of messages such as what classes or roles of users can access different fields of any message.
Since WSDL files are an XML-based specification for describing a web service, WSDL files are susceptible to attack. [6] To mitigate vulnerability of these files, limiting access to generated WSDL files, setting proper access restrictions on WSDL definitions, and avoiding unnecessary definitions in web services is encouraged.
XML Encryption is reported to have severe security concerns. [11] [12] Hypertext Transfer Protocol (HTTP): SAML relies heavily on HTTP as its communications protocol. Simple Object Access Protocol (SOAP): SAML specifies the use of SOAP, specifically SOAP 1.1 . [13] SAML defines XML-based assertions and protocols, bindings, and profiles.
Service Provisioning Markup Language (SPML) is an XML-based framework, being developed by OASIS, for exchanging user, resource and service provisioning information between cooperating organizations. The Service Provisioning Markup language is the open standard for the integration and interoperation of service provisioning requests.
