You can find more details on the enabling WildFly to use the out of the box Elytron components for securing the management interfaces in the Default Management Authentication Configuration section.
The elytron subsystem provides application-http-authentication by default which can be used to secure applications. For more details on how application-http-authentication is configured, see the Out of the Box Configuration section.
To configure applications to use application-http-authentication, see Configure Applications to Use Elytron or Legacy Security for Authentication. You can also override the default behavior of all applications using the steps in Override an Application's Authentication Configuration.
WildFly does provide a default one-way SSL/TLS configuration using the legacy core management authentication but does not provide one in the elytron subsystem. You can find more details on configuring SSL/TLS using the elytron subsystem for both the management interfaces as well as for applications in Configure SSL/TLS
In addition to securing applications and management interfaces, Elytron also integrates with other subsystems in WildFly.
|batch-jberet||You can configure the batch-jberet to run batch jobs using an Elytron security domain.|
|datasources||You can use a credential store or an Elytron security domain to provide authentication information in a datasource definition.|
|messaging-activemq||You can secure remote connections to the remote connections used by the messaging-activemq subsystem.|
|iiop-openjdk||You can use the elytron subsystem to configure SSL/TLS between clients and servers using the iiop-openjdk subsystem.|
|You can use a credential store to provide authentication information in a server definition in the mail subsystem.|
|undertow||You can use the elytron subsystem to configure both SSL/TLS and application authentication.|
There is adapter in webservices subsystem to make authentication works for elytron security domain automatically. Like configure with legacy security domain, you can configure elytron security domain in deployment descriptor or annotation to secure webservice endpoint.
As previously described, Elytron based security is configured by chaining together different capability references to form a complete security policy. To allow an incremental migration from the legacy Security subsystem some of the major components of this subsystem can be mapped to Elytron capabilities and used within an Elytron based set up.
