- All Implemented Interfaces:
Serializable,Guard
The
JDIPermission class represents access rights to
the VirtualMachineManager. This is the permission
which the SecurityManager will check when code that is running with
a SecurityManager requests access to the VirtualMachineManager, as
defined in the Java Debug Interface (JDI) for the Java platform.
A JDIPermission object 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 following table provides a summary description of what the permission allows, and discusses the risks of granting code the permission.
| Permission Target Name | What the Permission Allows | Risks of Allowing this Permission |
|---|---|---|
| virtualMachineManager | Ability to inspect and modify the JDI objects in the
VirtualMachineManager
|
This allows an attacker to control the
VirtualMachineManager and cause the system to
misbehave.
|
Programmers do not normally create JDIPermission objects directly. Instead they are created by the security policy code based on reading the security policy file.
