6 What is SOA? Service Oriented Architecture Term originated from IBM Web Services work in 2000? Million and one attempts to produce a catchy paragraph Strategy (both IT and Business) Services Interoperable Standards Aims to address perceived limitations in previous application integration techniques. 6

7 SOA Evolution Service Oriented Architecture Plateau of Productivity Not just about enabling a legacy application to be called as a web service. High level business process design SOA Maturity Model Availability of tools Server : Oracle SOA Suite (+ others, I guess!) Designer : Oracle JDeveloper (ditto) SCA Service Component Architecture (OASIS Standard) 7

8 What are Web Services? Not just an API! Salient points Platform independent (XML everywhere ) Transport independent (i.e. not tied to a specific protocol) Loosely coupled Contract Standards (next slide!) 8

9 What are Web Services? Gradual emergence of standards XML & XSD SOAP WSDL [Side note: even W3C gets confused between Web Service Definition Language and Web Services Description Language!] Java Platform JAX-RPC JAX-WS (initially called JAX-RPC 2.0) 9

10 Anatomy of a SOAP Message SOAP Envelope SOAP Header SOAP Body Message Payload 10

11 Anatomy of a WSDL Definition Messages Operations Ports 11

12 Content What is SOA? What is Web Services Security? Web Services Security in OTM Futures 12

13 Security Before Web Services Security Applies to OTM versions from v5.0 to v6.2 Credentials were passed according to transport protocol For example, SOAP over HTTP used Basic Authentication HTTP Header Encryption required SOAP over HTTPS Commonly include credentials in the message itself. OTM accepted Transmission Header with username/password or username and IP authentication. 13

14 Web Services Security WS-Security WSS: SOAP Message Security v1.1 OASIS Specification of an XML syntax for security related data in the SOAP Header Supports different profiles Username Token Profile SAML Token Profile X.509 Token Profile Kerberos Token Profile Rights Expression Language (REL) Token Profile 14

15 Web Services Policy WS-Policy WSP: Web Service Policy 1.5 Framework & Attachment W3C Recommendation for an XML syntax to describe the requirements and capabilities of a web service. Defines the concept of an assertion and how to declare policy alternatives. Examples :- Security Transactions Reliable Messaging Addressing 15

16 Web Services Security Policy WS-SecurityPolicy WSSP: WS-SecurityPolicy 1.3 OASIS Specification for WSS related policy assertions Service can specify which token profiles are required or supported Service can specify which transport protocols are required or supported Declared in the service WSDL 16

17 WSSP Example Username Token 17

18 Content What is SOA? What is Web Services Security? Web Services Security in OTM Futures 18

19 WSS in OTM v6.2 - Inbound Partial support for Username Token Profile Full support for HTTP and HTTPS Not declared in WSDL Password Digest was initially supported but may be removed 19

20 WSS in OTM v6.2 - Outbound Partial support for Username Token Profile Full support for HTTP and HTTPS External WSDL is not parsed for WSSP assertions Password Digest was initially supported but may be removed Requires settings on Web Service and External System records in OTM. 20

21 Web Service Manager 21

22 External System Manager 22

23 WSS in OTM v6.3 - Inbound Full support for Username Token Profile (except Password Digest type) Full support for HTTP and HTTPS Full support for Message Encryption Declares security policy in WSDL for inbound services Defaults to Username Token over HTTPS Policy can be customised 23

24 24

25 Custom Policy Installation deploys a policy file for each web service <otm home>/glog/glog_resources/policies/<service name>-policy.xml For example, <otm home>/glog/glog_resources/policies/intxmlservice-policy.xml To override default policy DO NOT EDIT base file Create file under configured custom directory, for example <otm home>/glog/glog_resources/custom/policies/intxmlservice- Policy.xml 25

26 Custom Policy (contd.) Sample files installed otm-default-policy.xml policy installed by default (currently Username Token over HTTPS) otm-wssp https-usernametoken-plain.template.xml otm-wssp usernametoken-plain.template.xml otm-wssp1.2- wss10_username_token_with_message_protection_policy.template.xml 26

27 WSS in OTM v6.3 Outbound Full support for Username Token Profile (except Password Digest type) Full support for HTTP and HTTPS Full support for Message Encryption WebLogic Server handles parsing of policy assertions Requires additional WebLogic Server administration All pre-existing outbound Web Services defined in OTM will operate according to v6.2 logic i.e. will not automatically have access to v6.3 capability 27

28 WSS in OTM v6.3 Outbound (contd.) WSDL Document content needs to be URL Existing records would not contain any WS-Policy details and so need to be reloaded. Use of Message Encryption requires additional administration tasks. Storage of external X.509 Certificate in WebLogic keystore New Web Service Security Configuration via Console (or config.xml) Configure OTM property to match keystore alias to service endpoint glog.webservice.pki.alias.myalias= onservice 28

29 WSS in OTM v6.3 Outbound (contd.) Credential Mapping 29
