| * 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. |
| * |
| * <P> |
| * The target name is the name of the Serializable permission (see below). |
| * |
| * <P> |
| * 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. |
| * <P> |
| * |
| * <table border=1 cellpadding=5 summary="Permission target name, what the permission allows, and associated risks"> |

| * <td>enableSubclassImplementation</td> |
| * <td>Subclass implementation of ObjectOutputStream or ObjectInputStream |
| * to override the default serialization or deserialization, respectively, |
| * of objects</td> |
| * <td>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.</td> |
| * </tr> |
| * |
| * <tr> |
| * <td>enableSubstitution</td> |
| * <td>Substitution of one object for another during |
| * serialization or deserialization</td> |

| * malignant data.</td> |
