Info

The CSIv2 configuration properties are listed below. Certain security properties have supported/required property pairs. If the required property is enabled then communication with the server must satisfy this property. ► ► ► ► ► ► com.ibm.CSI.performStateful (true, false / true) - determines whether the authentication request should result in a stateful reply returning from the server. com.ibm.CSI.performTLClientAuthenticationRequired (true, false / false) and com.ibm.CSI.performTLClientAuthenticationSupported (true, false / false) - determines if transport-layer client authentication is required or supported. This will involve the client sending a digital certificate to the server during the authentication stage. If the Required property is set to true, the client will only authenticate with servers that support transport-layer client authentication. com.ibm.CSI.performTransportAssocSSLTLSRequired (true, false / false) and com.ibm.CSI.performTransportAssocSSLTLSSupported (true, false / true) - determines if the client can use SSL to communicate with the server. If the Required property is set to true, the client will only communicate with servers that support SSL. com.ibm.CSI.performClientAuthenticationRequired (true, false / true) and com.ibm.CSI.performClientAuthenticationSupported (true, false / true) - determines if message layer client authentication is required or supported. The com.ibm.CORBA.authenticationTarget property determines the type of authentication mechanism. com.ibm.CSI.performMessageIntegrityRequired (true, false / true) and com.ibm.CSI.performMessageIntegritySupported (true, false / true) - determines if a connection secured by a 40-bit cipher is supported or required. If the Required property is set to true then the connection will fail if the server does not support 40-bit ciphers. This property is only valid when SSL is enabled. com.ibm.CSI.performMessageConfidentialityRequired (true, false / false) and com.ibm.CSI.performMessageConfidentialitySupported (true, false / true) - determines if a connection secured by a 128-bit cipher is supported or required. If the Required property is set to true then the connection will fail if the server does not support 128-bit ciphers. This property is only valid when SSL is enabled. For a more complete list of directives, refer to the WebSphere Application Server InfoCenter for more details. The Application Server should also be configured to communicate with a client in the required fashion. If a Java client requires that client certificates be transmitted via SSL, for example, then the server must be set to expect this. Details on the configuration of the Application Server can be found in Chapter 10, “Administering WebSphere security” on page 233. 106 IBM WebSphere V5.0 Security Handbook
6.4 Identity Assertion Definition: Identity assertion is basically the process taking place when the invocation credential is asserted to the downstream server during a call. When a client authenticates to a server, the received credential is set. When authorization checks the credential to see if it is allowed access, it will also set the invocation credential so that if the EJB method calls another EJB method located on other servers, the invocation credential can be used as the identity to invoke the downstream method. Depending on the RunAs mode for the EJB, the invocation credential will be set as the originating client identity, the server's identity, or a specified different identity. Regardless of the identity that is set, when Identity Assertion is enabled, it is the invocation credential that is asserted to the downstream server. The invocation credential identity is sent to the downstream server in an identity token. In addition, the sending server's identity, including password or token, is sent in the client authentication token. Both are needed by the receiving server to accept the asserted identity. The receiving server does the following to accept the asserted identity. 1. First, it is determined whether the sending server's identity is on the trusted principal list of the receiving server. That is, is the sending server one which is allowed to send an identity token to the receiving server? 2. Second, once we have determined that the sending server is on the trusted list, we need to make sure it truly is the sending server by authenticating it. This could be simply comparing the user ID and password from the sending server to that of the receiving server. Or it could require a real authenticate call. 3. If the sending server's credentials are authenticated and on the trusted principal list, then evaluation of the identity token can proceed. Evaluation of the identity token consists of the following. There are four formats of identities which can be present in an identity token: – Principal name – Distinguished name – Certificate chain – Anonymous identity The WebSphere Application Servers that receive authentication information typically support all four identity types. The sending server decides which one will be chosen based on how the original client authenticated. The type that is present depends on how the client originally authenticates to the sending Chapter 6. Securing Java clients 107
