Abstract level security interception classes which are responsible for enforcing the configured security constraints for a secure object.

A secure object is a term frequently used throughout the security system. It does not refer to a business object that is being secured, but instead refers to some infrastructure object that can have security facilities provided for it by Spring Security. For example, one secure object would be MethodInvocation, whilst another would be HTTP Note these are infrastructure objects and their design allows them to represent a large variety of actual resources that might need to be secured, such as business objects or HTTP request URLs.

Each secure object typically has its own interceptor package. Each package usually includes a concrete security interceptor (which subclasses AbstractSecurityInterceptor) and an appropriate SecurityMetadataSource for the type of resources the secure object represents.
