java.lang.management
Class ManagementPermission
- Guard, Serializable
Represents the permission to view or modify the data
which forms part of the system management interfaces.
Calls to methods of the system management beans,
provided by the
ManagementFactory, may perform
checks against the current
SecurityManager
(if any) before allowing the operation to proceed.
Instances of this object are supplied to the
SecurityManager in order to perform
these checks. It is not normal for instances of this
class to be created outside the use of the
SecurityManager.
This object can represent two types of management
permission:
- monitor — this allows access
to information such as the arguments supplied to the
virtual machine, the currently loaded classes and the
stack traces of running threads. Malicious code may
use this to obtain information about the system and
exploit any vulnerabilities found.
- control — this allows the
information stored by the management beans to be altered.
For example, additional debugging information (such
as class loading traces) may be turned on or memory
usage limits changed. Malicious code could use
this to alter the behaviour of the system.
