4. ESRIN, 15 July 2009 Introduction  The Toolbox is a framework which facilitate the integration of web services in the HMA infrastructure.  The component that has been provided in this project is finalized of providing WS-Security at Ground Segment level, enabling existing GS to wrap and connect their own catalogues/services to the HMA infrastructure.  It implements OGC 07-118r1 0.0.5  Both internal (deployed on the Toolbox) and external (proxy) services can be secured with this extension.

8. ESRIN, 15 July 2009 Toolbox Security Architecture  Axis2 as basic SOAP engine  Axis2 module Rampart (Apache Software Foundation) for WS-Security layer: its behaviour has been extended to cover the HMAT security requirements (HMAT- SRD-1200-INT_1.1)  ToolboxSecurityWrapper: Axis2 service with link to the Policy Enforcement Point (PEP, Application Security Layer) and Toolbox Application Layer Axis2 RAMPART 4HMAT RAMPART 4HMAT WS-Policy ToolboxSecurity Wrapper (Axis2 service) Service Description ToolboxPEP XACML Policies Toolbox Application Layer SOAP

10. ESRIN, 15 July 2009 Toolbox Security Architecture: ToolboxPDP  ToolboxPDP: invoked by the ToolboxSecurityWrapper when WS-Security check is successful; enforces XACML policies check  XACML policies are stored in dedicated XML files  Each policy owns information about the wrapped service and (optionally) SOAP action for which the policy applies Owns a list of policy rules; each rule can refer SAML token and/or SOAP (body) attributes values. ToolboxPEP XACML Policies

11. ESRIN, 15 July 2009 XACML example for EO EbRim profile (1/3) The target wrapped service for which this policy applies: wrs (Web Registry Service)

14. ESRIN, 15 July 2009 Proxy patterns supported Service Toolbox PEP http requestresponse Secured Client External Service http requestresponse Service Toolbox PEP http requestresponse Secured Client External Service http requestresponse PEP The token can be not encrypted or encrypted with the public key of the receiver

15. ESRIN, 15 July 2009 General configuration Slide 15 This keystore should contains all the public key of the trusted IDP. The Toolbox uses this keys to check the signature. It loops on all the keys and go ahead only if a key allow checking the signature

16. ESRIN, 15 July 2009 Service creation: Catalogue proxy (1) Slide 16 Select the service name and click on Next Select the type of service and click on Next Enter a Service Abstract and a Service Description and click on next

17. ESRIN, 15 July 2009 Service creation: Catalogue proxy (2) Slide 17 Select the interface and click on Next Select the type of Service and click on Next Enter the security parameters and click on next Upload the keystore storing the service private KEY to be used to decrypt the incoming tokens. In case the service is configured as security proxy and the outgoing messages have to be re-encrypted the keystore should also contain the public key of the connected end point. Enter Alias and Password: - Alias is the identifier of the key in the keystore - Password of the keystore Enter Alias and Password: - Alias is the identifier of the key in the keystore - Password of the keystore XACML file specifying the filtering rules to be applied to the incoming messages.

18. ESRIN, 15 July 2009 Service creation: Catalogue proxy (3) Slide 18 Configure the type of proxy you want to create and click on configure Select the operation you want to proxy Tick this if you want to forward the message with the security token unencrypted Tick this if you want to forward the message with the security token encrypted using the key of the receiver (to be included in the keystore of the service and identified via the Alias below) End point of the receiver Alias of the key to be used to encrypt the security token
