SerializablePermissionpublic final class SerializablePermission extends BasicPermission | 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 all the possible 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 |
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. |

public SerializablePermission(String name)Creates a new SerializablePermission with the specified name.
The name is the symbolic name of the SerializablePermission, such as
"enableSubstitution", etc.
super(name);
| public SerializablePermission(String name, String actions)Creates a new SerializablePermission object with the specified name.
The name is the symbolic name of the SerializablePermission, and the
actions String is currently unused and should be null.
super(name, actions);
