Provides core security classes of the Acegi Security System for Spring.

The {@link net.sf.acegisecurity.SecurityInterceptor} is the main class. It delegates to two interfaces, {@link net.sf.acegisecurity.AuthenticationManager} and {@link net.sf.acegisecurity.AccessDecisionManager} for authentication and authorization respectively.

When configuring SecurityInterceptor in the bean context, each method to be secured is provided a comma separated list of configuration attributes ({@link net.sf.acegisecurity.ConfigAttribute}). These configuration attributes are relevant only to AccessDecisionManagers.

Read the JavaDocs of the key classes listed above to learn more about how the security classes operate.
