CXF supports WS-SecurityPolicy versions 1.1 and later. It does not support WS-SecurityPolicy 1.0.

Enabling WS-SecurityPolicy

In CXF 2.2, if the cxf-rt-ws-policy and cxf-rt-ws-security modules are available on the classpath, the WS-SecurityPolicy stuff is automatically enabled. Since the entire security runtime is policy driven, the only requirement is that the policy engine and security policies be available.

If you are using the full "bundle" jar, all the security and policy stuff is already included.

Policy description

With WS-SecurityPolicy, the binding and/or operation in the wsdl references a WS-Policy fragment that describes the basic security requirements for interacting with that service. The WS-SecurityPolicy specification allows for specifying things like asymmetric/symmetric keys, using transports (https) for encryption, which parts/headers to encrypt or sign, whether to sign then encrypt or encrypt then sign, whether to include timestamps, whether to use derived keys, etc... Basically, it describes what actions are necessary to securely interact with the service described in the WSDL.

However, the WS-SecurityPolicy fragment does not include "everything" that is required for a runtime to be able to able to create the messages. It does not describe things such as locations of key stores, user names and passwords, etc... Those need to be configured in at runtime to augment the WS-SecurityPolicy fragment.

Configuring the extra properties

There are several extra properties that may need to be set to provide the additional bits of information to the runtime. Note that you should check that a particular property is supported in the version of CXF you are using.

User properties

ws-security.username

The user's name. It is used differently by each of the WS-Security functions, see here for more information.

ws-security.password

The user's password when "ws-security.callback-handler" is not defined. It is currently only used for the case of adding a password to a UsernameToken.

ws-security.signature.username

The user's name for signature. It is used as the alias name in the keystore to get the user's cert and private key for signature. See here for more information.

ws-security.encryption.username

The user's name for encryption. It is used as the alias name in the keystore to get the user's public key for encryption. See here for more information.

Callback Class and Crypto properties

ws-security.callback-handler

The CallbackHandler implementation class used to obtain passwords.

ws-security.saml-callback-handler

The SAML CallbackHandler implementation class used to construct SAML Assertions.

ws-security.signature.properties

The Crypto property configuration to use for signature, if "ws-security.signature.crypto" is not set instead.

ws-security.encryption.properties

The Crypto property configuration to use for encryption, if "ws-security.encryption.crypto" is not set instead.

ws-security.signature.crypto

A Crypto object to be used for signature. If this is not defined then "ws-security.signature.properties" is used instead.

ws-security.encryption.crypto

A Crypto object to be used for encryption. If this is not defined then "ws-security.encryption.properties" is used instead.

Note: for Symmetric bindings that specify a protection token, the ws-security-encryption properties are used.

Boolean WS-Security configuration tags, e.g. the value should be "true" or "false".

Backwards compatibility configuration note

From Apache CXF 3.1.0, some of the WS-Security based configuration tags have been changed to just start with "security-". This is so that they can be shared with the JAX-RS XML Security component. Apart from the prefix change, the tags are exactly the same. Older "ws-security-" values continue to be accepted in CXF 3.1.0. See the Security Configuration page for information on the new shared configuration tags.

Configuring the extra properties

There are several extra properties that may need to be set to provide the additional bits of information to the runtime. Note that you should check that a particular property is supported in the version of CXF you are using. First, see the Security Configuration page for information on the configuration tags that are shared with the JAX-RS XML Security component. Here are configuration tags that only apply to the WS-SecurityPolicy layer, and hence all start with "ws-security" (as opposed to the common tags which now start with "security-").

 

Boolean WS-Security configuration tags, e.g. the value should be "true" or "false".

constant

default

definition

ws-security.validate.token

true

Whether to validate the password of a received UsernameToken or not.

ws-security.username-token.always.encrypted

ws-security.sc.jaas-subjecttrueSet this to "false" if security context must not be created from JAAS Subject.
ws-security.validate.audience-restriction(varies)

If this is set to "true", then IF the SAML Token contains Audience Restriction URIs, one of them must match either the request URL or the Service QName. The default is "true" for CXF 3.0.x, and "false" for 2.7.x.

Non-boolean WS-Security Configuration parameters

A comma separated String of regular expressions which will be applied to the subject DN of the certificate used for signature validation, after trust verification of the certificate chain associated with the certificate. These constraints are not used when the certificate is contained in the keystore (direct trust)

ws-security.timestamp.timeToLive

The time in seconds to append to the Creation value of an incoming Timestamp to determine whether to accept the Timestamp as valid or not. The default value is 300 seconds (5 minutes).

ws-security.timestamp.futureTimeToLive

The time in seconds in the future within which the Created time of an incoming Timestamp is valid. The default value is "60". See here for more information.

ws-security.saml-role-attributename

The attribute URI of the SAML AttributeStatement where the role information is stored. The default is "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/role".. The default value is "60". See here for more information.

ws-security.spnego.client.action

The SpnegoClientAction implementation to use for SPNEGO. This allows the user to plug in a different implementation to obtain a service ticket.

ws-security.nonce.cache.instance

This holds a reference to a ReplayCache instance used to cache UsernameToken nonces. The default instance that is used is the EHCacheReplayCache.

ws-security.timestamp.cache.instance

This holds a reference to a ReplayCache instance used to cache Timestamp Created Strings. The default instance that is used is the EHCacheReplayCache.

ws-security.saml.cache.instanceThis holds a reference to a ReplayCache instance used to cache SAML2 Token Identifiers, when the token has a "OneTimeUse" Condition. The default instance that is used is the EHCacheReplayCache.

ws-security.cache.config.file

Set this property to point to a configuration file for the underlying caching implementation. The default configuration file that is used is cxf-ehcache.xml in the cxf-rt-ws-security module.

org.apache.cxf.ws.security.tokenstore.TokenStore

The TokenStore instance to use to cache security tokens. By default this uses the EHCacheTokenStore if EhCache is available. Otherwise it uses the MemoryTokenStore.

ws-security.cache.identifierThe Cache Identifier to use with the TokenStore. CXF uses the following key to retrieve a token store: "org.apache.cxf.ws.security.tokenstore.TokenStore-<identifier>". This key can be used to configure service-specific cache configuration. If the identifier does not match, then it falls back to a cache configuration with key "org.apache.cxf.ws.security.tokenstore.TokenStore". The default "<identifier>" is the QName of the service in question.

ws-security.subject.cert.constraints

default "<identifier>" is the QName of the service in question.

ws-security.role.classifier

If one of the WSS4J Validators returns a JAAS Subject from Validation, then the WSS4JInInterceptor will attempt to create a SecurityContext based on this Subject. If this value is not specified, then it tries to get roles using the DefaultSecurityContext in cxf-rt-core. Otherwise it uses this value in combination with the SUBJECT_ROLE_CLASSIFIER_TYPE to get the roles from the Subject.

ws-security.role.classifier.type

If one of the WSS4J Validators returns a JAAS Subject from Validation, then the WSS4JInInterceptor will attempt to create a SecurityContext based on this Subject. Currently accepted values are "prefix" or "classname". Must be used in conjunction with the SUBJECT_ROLE_CLASSIFIER. The default value is "prefix".

ws-security.asymmetric.signature.algorithm

This configuration tag overrides the default Asymmetric Signature algorithm (RSA-SHA1) for use in WS-SecurityPolicy, as the WS-SecurityPolicy specification does not allow the use of other algorithms at present.

ws-security.password.encryptor.instance

A PasswordEncryptor instance, which is used to encrypt or decrypt passwords in the Merlin Crypto implementation

ws-security.delegated.credentialA delegated credential to use for WS-Security. Currently only a Kerberos GSSCredential Object is supported. This is used to retrieve a service ticket instead of using the client credentials.
