Web Application Security

<debug>

Enables Spring Security debugging infrastructure. This will provide human-readable (multi-line) debugging information to monitor requests coming into the security filters. This may include sensitive information, such as request parameters or headers, and should only be used in a development environment.

<http>

If you use an <http> element within your application, a FilterChainProxy bean named "springSecurityFilterChain" is created and the configuration within the element is used to build a filter chain within FilterChainProxy. As of Spring Security 3.1, additional http elements can be used to add extra filter chains [1] for how to set up the mapping from your web.xml ]. Some core filters are always created in a filter chain and others will be added to the stack depending on the attributes and child elements which are present. The positions of the standard filters are fixed (see the filter order table in the namespace introduction), removing a common source of errors with previous versions of the framework when users had to configure the filter chain explicitly in the FilterChainProxy bean. You can, of course, still do this if you need full control of the configuration.

All filters which require a reference to the AuthenticationManager will be automatically injected with the internal instance created by the namespace configuration.

Each <http> namespace block always creates an SecurityContextPersistenceFilter, an ExceptionTranslationFilter and a FilterSecurityInterceptor. These are fixed and cannot be replaced with alternatives.

<http> Attributes

The attributes on the <http> element control some of the properties on the core filters.

  • access-decision-manager-ref Optional attribute specifying the ID of the AccessDecisionManager implementation which should be used for authorizing HTTP requests. By default an AffirmativeBased implementation is used for with a RoleVoter and an AuthenticatedVoter.

  • authentication-manager-ref A reference to the AuthenticationManager used for the FilterChain created by this http element.

  • auto-config Automatically registers a login form, BASIC authentication, logout services. If set to "true", all of these capabilities are added (although you can still customize the configuration of each by providing the respective element). If unspecified, defaults to "false". Use of this attribute is not recommended. Use explicit configuration elements instead to avoid confusion.

  • create-session Controls the eagerness with which an HTTP session is created by Spring Security classes. Options include:

    • always - Spring Security will proactively create a session if one does not exist.

    • ifRequired - Spring Security will only create a session only if one is required (default value).

    • never - Spring Security will never create a session, but will make use of one if the application does.

    • stateless - Spring Security will not create a session and ignore the session for obtaining a Spring Authentication.

  • disable-url-rewriting Prevents session IDs from being appended to URLs in the application. Clients must use cookies if this attribute is set to true. The default is true.

  • entry-point-ref Normally the AuthenticationEntryPoint used will be set depending on which authentication mechanisms have been configured. This attribute allows this behaviour to be overridden by defining a customized AuthenticationEntryPoint bean which will start the authentication process.

  • jaas-api-provision If available, runs the request as the Subject acquired from the JaasAuthenticationToken which is implemented by adding a JaasApiIntegrationFilter bean to the stack. Defaults to false.

  • name A bean identifier, used for referring to the bean elsewhere in the context.

  • once-per-request Corresponds to the observeOncePerRequest property of FilterSecurityInterceptor. Defaults to true.

  • pattern Defining a pattern for the http element controls the requests which will be filtered through the list of filters which it defines. The interpretation is dependent on the configured request-matcher. If no pattern is defined, all requests will be matched, so the most specific patterns should be declared first.

  • realm Sets the realm name used for basic authentication (if enabled). Corresponds to the realmName property on BasicAuthenticationEntryPoint.

  • request-matcher Defines the RequestMatcher strategy used in the FilterChainProxy and the beans created by the intercept-url to match incoming requests. Options are currently mvc, ant, regex and ciRegex, for Spring MVC, ant, regular-expression and case-insensitive regular-expression respectively. A separate instance is created for each intercept-url element using its pattern, method and servlet-path attributes. Ant paths are matched using an AntPathRequestMatcher, regular expressions are matched using a RegexRequestMatcher and for Spring MVC path matching the MvcRequestMatcher is used. See the Javadoc for these classes for more details on exactly how the matching is performed. Ant paths are the default strategy.

  • request-matcher-ref A reference to a bean that implements RequestMatcher that will determine if this FilterChain should be used. This is a more powerful alternative to pattern.

  • security A request pattern can be mapped to an empty filter chain, by setting this attribute to none. No security will be applied and none of Spring Security’s features will be available.

  • security-context-explicit-save If true, use SecurityContextHolderFilter instead of SecurityContextPersistenceFilter. Requires explicit save

  • security-context-repository-ref Allows injection of a custom SecurityContextRepository into the SecurityContextPersistenceFilter.

  • servlet-api-provision Provides versions of HttpServletRequest security methods such as isUserInRole() and getPrincipal() which are implemented by adding a SecurityContextHolderAwareRequestFilter bean to the stack. Defaults to true.

  • use-expressions Enables EL-expressions in the access attribute, as described in the chapter on expression-based access-control. The default value is true.

<access-denied-handler>

This element allows you to set the errorPage property for the default AccessDeniedHandler used by the ExceptionTranslationFilter, using the error-page attribute, or to supply your own implementation using the ref attribute. This is discussed in more detail in the section on the ExceptionTranslationFilter.

Parent Elements of <access-denied-handler>

<access-denied-handler> Attributes

  • error-page The access denied page that an authenticated user will be redirected to if they request a page which they don’t have the authority to access.

  • ref Defines a reference to a Spring bean of type AccessDeniedHandler.

<cors>

This element allows for configuring a CorsFilter. If no CorsFilter or CorsConfigurationSource is specified and Spring MVC is on the classpath, a HandlerMappingIntrospector is used as the CorsConfigurationSource.

<cors> Attributes

The attributes on the <cors> element control the headers element.

  • ref Optional attribute that specifies the bean name of a CorsFilter.

  • cors-configuration-source-ref Optional attribute that specifies the bean name of a CorsConfigurationSource to be injected into a CorsFilter created by the XML namespace.

<headers>

This element allows for configuring additional (security) headers to be send with the response. It enables easy configuration for several headers and also allows for setting custom headers through the header element. Additional information, can be found in the Security Headers section of the reference.

  • Feature-Policy - Can be set using the feature-policy element, Feature-Policy is a mechanism that allows web developers to selectively enable, disable, and modify the behavior of certain APIs and web features in the browser.

  • Cross-Origin-Opener-Policy - Can be set using the cross-origin-opener-policy element, Cross-Origin-Opener-Policy is a mechanism that allows you to ensure a top-level document does not share a browsing context group with cross-origin documents.

  • Cross-Origin-Embedder-Policy - Can be set using the cross-origin-embedder-policy element, Cross-Origin-Embedder-Policy is a mechanism that prevents a document from loading any cross-origin resources that don’t explicitly grant the document permission.

  • Cross-Origin-Resource-Policy - Can be set using the cross-origin-resource-policy element, Cross-Origin-Resource-Policy is a mechanism that conveys a desire that the browser blocks no-cors cross-origin/cross-site requests to the given resource.

    • DENY The page cannot be displayed in a frame, regardless of the site attempting to do so. This is the default when frame-options-policy is specified.

    • SAMEORIGIN The page can only be displayed in a frame on the same origin as the page itself

    In other words, if you specify DENY, not only will attempts to load the page in a frame fail when loaded from other sites, attempts to do so will fail when loaded from the same site. On the other hand, if you specify SAMEORIGIN, you can still use the page in a frame as long as the site including it in a frame it is the same as the one serving the page.

  • xss-protection-block When true and xss-protection-enabled is true, adds mode=block to the header. This indicates to the browser that the page should not be loaded at all. When false and xss-protection-enabled is true, the page will still be rendered when an reflected attack is detected but the response will be modified to protect against the attack. Note that there are sometimes ways of bypassing this mode which can often times make blocking the page more desirable.

  • key The key shared between the provider and filter. This generally does not need to be set. If unset, it will default to a secure randomly generated value. This means setting this value can improve startup time when using the anonymous functionality since secure random values can take a while to be generated.

  • username The username that should be assigned to the anonymous request. This allows the principal to be identified, which may be important for logging and auditing. if unset, defaults to anonymousUser.

It is used to construct the FilterInvocationSecurityMetadataSource used by the FilterSecurityInterceptor. It is also responsible for configuring a ChannelProcessingFilter if particular URLs need to be accessed by HTTPS, for example. When matching the specified patterns against an incoming request, the matching is done in the order in which the elements are declared. So the most specific patterns should come first and the most general should come last.

Parent Elements of <intercept-url>

<intercept-url> Attributes

  • access Lists the access attributes which will be stored in the FilterInvocationSecurityMetadataSource for the defined URL pattern/method combination. This should be a comma-separated list of the security configuration attributes (such as role names).

  • method The HTTP Method which will be used in combination with the pattern and servlet path (optional) to match an incoming request. If omitted, any method will match. If an identical pattern is specified with and without a method, the method-specific match will take precedence.

  • pattern The pattern which defines the URL path. The content will depend on the request-matcher attribute from the containing http element, so will default to ant path syntax.

  • request-matcher-ref A reference to a RequestMatcher that will be used to determine if this <intercept-url> is used.

  • requires-channel Can be "http" or "https" depending on whether a particular URL pattern should be accessed over HTTP or HTTPS respectively. Alternatively the value "any" can be used when there is no preference. If this attribute is present on any <intercept-url> element, then a ChannelProcessingFilter will be added to the filter stack and its additional dependencies added to the application context.

If a <port-mappings> configuration is added, this will be used to by the SecureChannelProcessor and InsecureChannelProcessor beans to determine the ports used for redirecting to HTTP/HTTPS.

This property is invalid for filter-security-metadata-source
  • servlet-path The servlet path which will be used in combination with the pattern and HTTP method to match an incoming request. This attribute is only applicable when request-matcher is 'mvc'. In addition, the value is only required in the following 2 use cases: 1) There are 2 or more HttpServlet 's registered in the ServletContext that have mappings starting with '/' and are different; 2) The pattern starts with the same value of a registered HttpServlet path, excluding the default (root) HttpServlet '/'.

This property is invalid for filter-security-metadata-source

<jee>

Adds a J2eePreAuthenticatedProcessingFilter to the filter chain to provide integration with container authentication.

Parent Elements of <jee>

<jee> Attributes

  • mappable-roles A comma-separate list of roles to look for in the incoming HttpServletRequest.

  • user-service-ref A reference to a user-service (or UserDetailsService bean) Id

<logout>

Adds a LogoutFilter to the filter stack. This is configured with a SecurityContextLogoutHandler.

Parent Elements of <logout>

<logout> Attributes

  • delete-cookies A comma-separated list of the names of cookies which should be deleted when the user logs out.

  • invalidate-session Maps to the invalidateHttpSession of the SecurityContextLogoutHandler. Defaults to "true", so the session will be invalidated on logout.

  • logout-success-url The destination URL which the user will be taken to after logging out. Defaults to <form-login-login-page>/?logout (i.e. /login?logout)

    Setting this attribute will inject the SessionManagementFilter with a SimpleRedirectInvalidSessionStrategy configured with the attribute value. When an invalid session ID is submitted, the strategy will be invoked, redirecting to the configured URL.

  • logout-url The URL which will cause a logout (i.e. which will be processed by the filter). Defaults to "/logout".

  • success-handler-ref May be used to supply an instance of LogoutSuccessHandler which will be invoked to control the navigation after logging out.

<openid-login>

Similar to <form-login> and has the same attributes. The default value for login-processing-url is "/login/openid". An OpenIDAuthenticationFilter and OpenIDAuthenticationProvider will be registered. The latter requires a reference to a UserDetailsService. Again, this can be specified by id, using the user-service-ref attribute, or will be located automatically in the application context.

Parent Elements of <openid-login>

<openid-login> Attributes

  • always-use-default-target Whether the user should always be redirected to the default-target-url after login.

  • authentication-details-source-ref Reference to an AuthenticationDetailsSource which will be used by the authentication filter

  • authentication-failure-handler-ref Reference to an AuthenticationFailureHandler bean which should be used to handle a failed authentication request. Should not be used in combination with authentication-failure-url as the implementation should always deal with navigation to the subsequent destination

  • authentication-failure-url The URL for the login failure page. If no login failure URL is specified, Spring Security will automatically create a failure login URL at /login?login_error and a corresponding filter to render that login failure URL when requested.

  • authentication-success-forward-url Maps a ForwardAuthenticationSuccessHandler to authenticationSuccessHandler property of UsernamePasswordAuthenticationFilter.

  • authentication-failure-forward-url Maps a ForwardAuthenticationFailureHandler to authenticationFailureHandler property of UsernamePasswordAuthenticationFilter.

  • authentication-success-handler-ref Reference to an AuthenticationSuccessHandler bean which should be used to handle a successful authentication request. Should not be used in combination with default-target-url (or always-use-default-target) as the implementation should always deal with navigation to the subsequent destination

  • default-target-url The URL that will be redirected to after successful authentication, if the user’s previous action could not be resumed. This generally happens if the user visits a login page without having first requested a secured operation that triggers authentication. If unspecified, defaults to the root of the application.

  • login-page The URL for the login page. If no login URL is specified, Spring Security will automatically create a login URL at /login and a corresponding filter to render that login URL when requested.

  • login-processing-url The URL that the login form is posted to. If unspecified, it defaults to /login.

  • password-parameter The name of the request parameter which contains the password. Defaults to "password".

  • user-service-ref A reference to a user-service (or UserDetailsService bean) Id

  • username-parameter The name of the request parameter which contains the username. Defaults to "username".

  • logout-response-resolver-ref Reference to the Saml2LogoutResponseResolver.

<attribute-exchange>

The attribute-exchange element defines the list of attributes which should be requested from the identity provider. An example can be found in the OpenID Support section of the namespace configuration chapter. More than one can be used, in which case each must have an identifier-match attribute, containing a regular expression which is matched against the supplied OpenID identifier. This allows different attribute lists to be fetched from different providers (Google, Yahoo etc).

Parent Elements of <attribute-exchange>

<attribute-exchange> Attributes

  • identifier-match A regular expression which will be compared against the claimed identity, when deciding which attribute-exchange configuration to use during authentication.

Child Elements of <attribute-exchange>

<openid-attribute>

Attributes used when making an OpenID AX Fetch Request

Parent Elements of <openid-attribute>

<openid-attribute> Attributes

  • count Specifies the number of attributes that you wish to get back. For example, return 3 emails. The default value is 1.

  • name Specifies the name of the attribute that you wish to get back. For example, email.

  • required Specifies if this attribute is required to the OP, but does not error out if the OP does not return the attribute. Default is false.

  • type Specifies the attribute type. For example, axschema.org/contact/email. See your OP’s documentation for valid attribute types.

<password-management>

This element configures password management.

Parent Elements of <password-management>

<password-management> Attributes

  • change-password-page The change password page. Defaults to "/change-password".

<port-mappings>

By default, an instance of PortMapperImpl will be added to the configuration for use in redirecting to secure and insecure URLs. This element can optionally be used to override the default mappings which that class defines. Each child <port-mapping> element defines a pair of HTTP:HTTPS ports. The default mappings are 80:443 and 8080:8443. An example of overriding these can be found in Redirect to HTTPS.

Parent Elements of <port-mappings>

Child Elements of <port-mappings>

<port-mapping>

Provides a method to map http ports to https ports when forcing a redirect.

Parent Elements of <port-mapping>

<port-mapping> Attributes

  • http The http port to use.

  • https The https port to use.

<remember-me>

Adds the RememberMeAuthenticationFilter to the stack. This in turn will be configured with either a TokenBasedRememberMeServices, a PersistentTokenBasedRememberMeServices or a user-specified bean implementing RememberMeServices depending on the attribute settings.

Parent Elements of <remember-me>

<remember-me> Attributes

  • authentication-success-handler-ref Sets the authenticationSuccessHandler property on the RememberMeAuthenticationFilter if custom navigation is required. The value should be the name of a AuthenticationSuccessHandler bean in the application context.

  • data-source-ref A reference to a DataSource bean. If this is set, PersistentTokenBasedRememberMeServices will be used and configured with a JdbcTokenRepositoryImpl instance.

  • remember-me-parameter The name of the request parameter which toggles remember-me authentication. Defaults to "remember-me". Maps to the "parameter" property of AbstractRememberMeServices.

  • key Maps to the "key" property of AbstractRememberMeServices. Should be set to a unique value to ensure that remember-me cookies are only valid within the one application [3]. If this is not set a secure random value will be generated. Since generating secure random values can take a while, setting this value explicitly can help improve startup times when using the remember-me functionality.

  • services-alias Exports the internally defined RememberMeServices as a bean alias, allowing it to be used by other beans in the application context.

  • services-ref Allows complete control of the RememberMeServices implementation that will be used by the filter. The value should be the id of a bean in the application context which implements this interface. Should also implement LogoutHandler if a logout filter is in use.

  • token-repository-ref Configures a PersistentTokenBasedRememberMeServices but allows the use of a custom PersistentTokenRepository bean.

  • token-validity-seconds Maps to the tokenValiditySeconds property of AbstractRememberMeServices. Specifies the period in seconds for which the remember-me cookie should be valid. By default it will be valid for 14 days.

  • user-service-ref The remember-me services implementations require access to a UserDetailsService, so there has to be one defined in the application context. If there is only one, it will be selected and used automatically by the namespace configuration. If there are multiple instances, you can specify a bean id explicitly using this attribute.

<request-cache> Element

Sets the RequestCache instance which will be used by the ExceptionTranslationFilter to store request information before invoking an AuthenticationEntryPoint.

Parent Elements of <request-cache>

<request-cache> Attributes

  • ref Defines a reference to a Spring bean that is a RequestCache.

<session-management>

Session-management related functionality is implemented by the addition of a SessionManagementFilter to the filter stack.

Parent Elements of <session-management>

<session-management> Attributes

  • invalid-session-url Setting this attribute will inject the SessionManagementFilter with a SimpleRedirectInvalidSessionStrategy configured with the attribute value. When an invalid session ID is submitted, the strategy will be invoked, redirecting to the configured URL.

  • invalid-session-url Allows injection of the InvalidSessionStrategy instance used by the SessionManagementFilter. Use either this or the invalid-session-url attribute but not both.

  • session-authentication-error-url Defines the URL of the error page which should be shown when the SessionAuthenticationStrategy raises an exception. If not set, an unauthorized (401) error code will be returned to the client. Note that this attribute doesn’t apply if the error occurs during a form-based login, where the URL for authentication failure will take precedence.

  • session-authentication-strategy-ref Allows injection of the SessionAuthenticationStrategy instance used by the SessionManagementFilter

  • session-fixation-protection Indicates how session fixation protection will be applied when a user authenticates. If set to "none", no protection will be applied. "newSession" will create a new empty session, with only Spring Security-related attributes migrated. "migrateSession" will create a new session and copy all session attributes to the new session. In Servlet 3.1 (Java EE 7) and newer containers, specifying "changeSessionId" will keep the existing session and use the container-supplied session fixation protection (HttpServletRequest#changeSessionId()). Defaults to "changeSessionId" in Servlet 3.1 and newer containers, "migrateSession" in older containers. Throws an exception if "changeSessionId" is used in older containers.

    If session fixation protection is enabled, the SessionManagementFilter is injected with an appropriately configured DefaultSessionAuthenticationStrategy. See the Javadoc for this class for more details.

Child Elements of <session-management>

<concurrency-control>

Adds support for concurrent session control, allowing limits to be placed on the number of active sessions a user can have. A ConcurrentSessionFilter will be created, and a ConcurrentSessionControlAuthenticationStrategy will be used with the SessionManagementFilter. If a form-login element has been declared, the strategy object will also be injected into the created authentication filter. An instance of SessionRegistry (a SessionRegistryImpl instance unless the user wishes to use a custom bean) will be created for use by the strategy.

Parent Elements of <concurrency-control>

<concurrency-control> Attributes

  • error-if-maximum-exceeded If set to "true" a SessionAuthenticationException will be raised when a user attempts to exceed the maximum allowed number of sessions. The default behaviour is to expire the original session.

  • expired-url The URL a user will be redirected to if they attempt to use a session which has been "expired" by the concurrent session controller because the user has exceeded the number of allowed sessions and has logged in again elsewhere. Should be set unless exception-if-maximum-exceeded is set. If no value is supplied, an expiry message will just be written directly back to the response.

  • expired-url Allows injection of the ExpiredSessionStrategy instance used by the ConcurrentSessionFilter

  • max-sessions Maps to the maximumSessions property of ConcurrentSessionControlAuthenticationStrategy. Specify -1 as the value to support unlimited sessions.

  • session-registry-alias It can also be useful to have a reference to the internal session registry for use in your own beans or an admin interface. You can expose the internal bean using the session-registry-alias attribute, giving it a name that you can use elsewhere in your configuration.

  • session-registry-ref The user can supply their own SessionRegistry implementation using the session-registry-ref attribute. The other concurrent session control beans will be wired up to use it.

<x509>

Adds support for X.509 authentication. An X509AuthenticationFilter will be added to the stack and an Http403ForbiddenEntryPoint bean will be created. The latter will only be used if no other authentication mechanisms are in use (its only functionality is to return an HTTP 403 error code). A PreAuthenticatedAuthenticationProvider will also be created which delegates the loading of user authorities to a UserDetailsService.

Parent Elements of <x509>

<x509> Attributes

  • authentication-details-source-ref A reference to an AuthenticationDetailsSource

  • subject-principal-regex Defines a regular expression which will be used to extract the username from the certificate (for use with the UserDetailsService).

  • user-service-ref Allows a specific UserDetailsService to be used with X.509 in the case where multiple instances are configured. If not set, an attempt will be made to locate a suitable instance automatically and use that.

<filter-chain-map>

Used to explicitly configure a FilterChainProxy instance with a FilterChainMap

<filter-chain-map> Attributes

  • request-matcher Defines the strategy to use for matching incoming requests. Currently the options are 'ant' (for ant path patterns), 'regex' for regular expressions and 'ciRegex' for case-insensitive regular expressions.

Child Elements of <filter-chain-map>

<filter-chain>

Used within to define a specific URL pattern and the list of filters which apply to the URLs matching that pattern. When multiple filter-chain elements are assembled in a list in order to configure a FilterChainProxy, the most specific patterns must be placed at the top of the list, with most general ones at the bottom.

Parent Elements of <filter-chain>

<filter-chain> Attributes

  • filters A comma separated list of references to Spring beans that implement Filter. The value "none" means that no Filter should be used for this FilterChain.

  • pattern A pattern that creates RequestMatcher in combination with the request-matcher

  • request-matcher-ref A reference to a RequestMatcher that will be used to determine if any Filter from the filters attribute should be invoked.

<filter-security-metadata-source>

Used to explicitly configure a FilterSecurityMetadataSource bean for use with a FilterSecurityInterceptor. Usually only needed if you are configuring a FilterChainProxy explicitly, rather than using the<http> element. The intercept-url elements used should only contain pattern, method and access attributes. Any others will result in a configuration error.

<filter-security-metadata-source> Attributes

  • id A bean identifier, used for referring to the bean elsewhere in the context.

  • request-matcher Defines the strategy use for matching incoming requests. Currently the options are 'ant' (for ant path patterns), 'regex' for regular expressions and 'ciRegex' for case-insensitive regular expressions.

  • use-expressions Enables the use of expressions in the 'access' attributes in <intercept-url> elements rather than the traditional list of configuration attributes. Defaults to 'true'. If enabled, each attribute should contain a single Boolean expression. If the expression evaluates to 'true', access will be granted.

Child Elements of <filter-security-metadata-source>


1. See the xref:servlet/configuration/xml-namespace.adoc#ns-web-xml[introductory chapter
2. This feature is really just provided for convenience and is not intended for production (where a view technology will have been chosen and can be used to render a customized login page). The class DefaultLoginPageGeneratingFilter is responsible for rendering the login page and will provide login forms for both normal form login and/or OpenID if required.
3. This doesn’t affect the use of PersistentTokenBasedRememberMeServices, where the tokens are stored on the server side.
