/**
 * This class is for Serializable permissions. A SerializablePermission
 * contains a name (also referred to as a "target name") but
 * no actions list; you either have the named permission
 * or you don't.
 *
 * 
 * The target name is the name of the Serializable permission (see below).
 *
 * 

 * The following table lists the standard {@code SerializablePermission} target names,
 * and for each provides a description of what the permission allows
 * and a discussion of the risks of granting code the permission.

enableSubclassImplementation Subclass implementation of ObjectOutputStream or ObjectInputStream
 * to override the default serialization or deserialization, respectively,
 * of objects Code can use this to serialize or
 * deserialize classes in a purposefully malfeasant manner. For example,
 * during serialization, malicious code can use this to
 * purposefully store confidential private field data in a way easily accessible
 * to attackers. Or, during deserialization it could, for example, deserialize
 * a class with all its private fields zeroed out.
enableSubstitution Substitution of one object for another during
 * serialization or deserialization This is dangerous because malicious code
 * can replace the actual object with one which has incorrect or
 * malignant data.
serialFilter Setting a filter for ObjectInputStreams. Code could remove a configured filter and remove protections
 *       already established.
