Class WebSecurity

  • All Implemented Interfaces:
    Service
    public final class WebSecurity
extends Object
implements Service
    Integration of security into Web Server.

    Methods that start with "from" are to register WebSecurity with WebServer - to create SecurityContext for requests:

    Example: 

     // Web server routing builder - this is our integration point
 Routing routing = Routing.builder()
 // register the WebSecurity to create context (shared by all routes)
 .register(WebSecurity.from(security))

    Other methods are to create security enforcement points (gates) for routes (e.g. you are expected to use them for a get, post etc. routes on specific path). These methods are starting points that provide an instance of SecurityHandler that has finer grained methods to control the gate behavior.
    Note that if any gate is configured, auditing will be enabled by default except for GET and HEAD methods - if you want to audit any method, invoke audit() to create a gate that will always audit the route. If you want to create a gate and not audit it, use SecurityHandler.skipAudit() on the returned instance.

    Example: 

     // continue from example above...
 // create a gate for method GET: authenticate all paths under /user and require role "user" for authorization
 .get("/user[/{*}]", WebSecurity.rolesAllowed("user"))

      • CONTEXT_ADD_HEADERS

        public static final String CONTEXT_ADD_HEADERS
        Security can accept additional headers to be added to security request. This will be used to obtain multivalue string map (a map of string to list of strings) from context (appropriate to the integration).

    • Method Detail

      • create

        public static WebSecurity create​(Security security)
        Create a consumer of routing config to be registered with web server routing to process security requests. This method is to be used together with other routing methods to protect web resources programmatically. Example: 
         .get("/user[/{*}]", WebSecurity.authenticate()
 .rolesAllowed("user"))
        Parameters:
        security - initialized security
        Returns:
        routing config consumer

      • create

        public static WebSecurity create​(Config config)
        Create a consumer of routing config to be registered with web server routing to process security requests. This method configures security and web server integration from a config instance
        Parameters:
        config - Config instance to load security and web server integration from configuration
        Returns:
        routing config consumer

      • create

        public static WebSecurity create​(Security security,
                                 Config config)
        Create a consumer of routing config to be registered with web server routing to process security requests. This method expects initialized security and creates web server integration from a config instance
        Parameters:
        security - Security instance to use
        config - Config instance to load security and web server integration from configuration
        Returns:
        routing config consumer

      • secure

        public static SecurityHandler secure()
        Secure access using authentication and authorization. Auditing is enabled by default for methods modifying content. When using RBAC (role based access control), just use rolesAllowed(String...). If you use a security provider, that requires additional data, use SecurityHandler.customObject(Object).

        Behavior:

        • Authentication: enabled and required
        • Authorization: enabled if provider configured
        • Audit: not modified (default: enabled except for GET and HEAD methods)
        Returns:
        SecurityHandler instance configured with authentication and authorization

      • authenticate

        public static SecurityHandler authenticate()
        If called, request will go through authentication process - defaults to false (even if authorize is true).

        Behavior:

        • Authentication: enabled and required
        • Authorization: not modified (default: disabled)
        • Audit: not modified (default: enabled except for GET and HEAD methods)
        Returns:
        SecurityHandler instance

      • audit

        public static SecurityHandler audit()
        Whether to audit this request - defaults to false for GET and HEAD methods, true otherwise. Request is audited with event type "request".

        Behavior:

        • Authentication: not modified (default: disabled)
        • Authorization: not modified (default: disabled)
        • Audit: enabled for any method this gate is registered on
        Returns:
        SecurityHandler instance

      • authenticator

        public static SecurityHandler authenticator​(String explicitAuthenticator)
        Use a named authenticator (as supported by security - if not defined, default authenticator is used).

        Behavior:

        • Authentication: enabled and required
        • Authorization: not modified (default: disabled)
        • Audit: not modified (default: enabled except for GET and HEAD methods)
        Parameters:
        explicitAuthenticator - name of authenticator as configured in Security
        Returns:
        SecurityHandler instance

      • authorizer

        public static SecurityHandler authorizer​(String explicitAuthorizer)
        Use a named authorizer (as supported by security - if not defined, default authorizer is used, if none defined, all is permitted).

        Behavior:

        • Authentication: enabled and required
        • Authorization: enabled with explicit provider
        • Audit: not modified (default: enabled except for GET and HEAD methods)
        Parameters:

        Returns:
        SecurityHandler instance

      • rolesAllowed

        public static SecurityHandler rolesAllowed​(String... roles)
        An array of allowed roles for this path - must have a security provider supporting roles.

        Behavior:

        • Authentication: enabled and required
        • Authorization: enabled
        • Audit: not modified (default: enabled except for GET and HEAD methods)
        Parameters:

        SecurityHandler instance

      • allowAnonymous

        public static SecurityHandler allowAnonymous()
