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 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. 

Permission target name, what the permission allows, and associated risks



Permission Target Name
What the Permission Allows
Risks of Allowing this 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.
