== Security
If Spring Security is on the classpath, then web applications are secure by default with
'`basic`' authentication on all HTTP endpoints. To add method-level security to a web
application, you can also add `@EnableGlobalMethodSecurity` with your desired settings.
Additional information can be found in the {spring-security-reference}#jc-method[Spring
If Spring Security is on the classpath, then web applications are secure by default. Spring Boot
relies on Spring Security’s content-negotiation strategy to determine whether to use `httpBasic`
or `formLogin`. To add method-level security to a web application, you can also add `@EnableGlobalMethodSecurity`
with your desired settings. Additional information can be found in the {spring-security-reference}#jc-method[Spring
Security Reference].

`org.springframework.boot.autoconfigure.security` category is set to log `INFO`-level
messages. Otherwise, the default password is not printed.
You can change the password by providing a `security.user.password`. This and other
useful properties are externalized via
{sc-spring-boot-autoconfigure}/security/SecurityProperties.{sc-ext}[`SecurityProperties`]
(properties with a prefix of "security").
The default security configuration is implemented in `SecurityAutoConfiguration` and in
the classes imported from there (`SpringBootWebSecurityConfiguration` for web security
and `AuthenticationManagerConfiguration` for authentication configuration, which is also
relevant in non-web applications). To switch off the default web application security
configuration completely, you can add a bean with `@EnableWebSecurity` (this does not
disable the authentication manager configuration or Actuator's security). To customize
it, you normally use external properties and beans of type `WebSecurityConfigurerAdapter`
(for example, to add form-based login).
NOTE: If you add `@EnableWebSecurity` and also disable Actuator security, you get the
default form-based login for the entire application, unless you add a custom
`WebSecurityConfigurerAdapter`.
configuration completely, you can add a bean of type `WebSecurityConfigurerAdapter` (this does not
disable the authentication manager configuration or Actuator's security).
To also switch off the authentication manager configuration, you can add a bean of type
`AuthenticationManager` or configure the global `AuthenticationManager` by autowiring an
`AuthenticationManagerBuilder` into a method in one of your `@Configuration` classes.
`UserDetailsService`, `AuthenticationProvider` or `AuthenticationManager`.
There are several secure applications in the {github-code}/spring-boot-samples/[Spring
Boot samples] to get you started with common use cases.
The basic features you get by default in a web application are:
* An `AuthenticationManager` bean with in-memory store and a single user (see
`SecurityProperties.User` for the properties of the user).
* Ignored (insecure) paths for common static resource locations (`+/css/**+`, `+/js/**+`,
`+/images/**+`, `+/webjars/**+`, and `+**/favicon.ico+`).
* HTTP Basic security for all other endpoints.
* Security events published to Spring's `ApplicationEventPublisher` (successful and
unsuccessful authentication and access denied).
* Common low-level features (HSTS, XSS, CSRF, caching) provided by Spring Security.
* A `UserDetailsService` bean with in-memory store and a single user with a generated password.
* Form-based login or HTTP Basic security (depending on Content-Type) for the entire application (including
actuator endpoints if actuator is on the classpath).
All of the above can be switched on and off or modified by setting external properties
(`+security.*+`). To override the access rules without changing any other auto-configured
features, add a `@Bean` of type `WebSecurityConfigurerAdapter` with
`@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)` and configure it to meet your needs.
NOTE: By default, a `WebSecurityConfigurerAdapter` matches any path. If you do not want
to completely override Spring Boot's auto-configured access rules, your adapter must
explicitly configure the paths that you do want to override.
Access rules can be overriden by adding a custom `WebSecurityConfigurerAdapter`. Spring Boot
provides convenience methods that can be used to override access rules for actuator endpoints
and static resources. `EndpointRequest` can be used to create a `RequestMatcher` that is based on the
`management.endpoints.web.base-path` property. `StaticResourceRequest` can be used to
create a `RequestMatcher` for static resources in commonly used locations.
