java.lang.management
class ManagementPermission
- All Implemented Interfaces:
- Serializable, Guard
public final class ManagementPermission
extends BasicPermission
The permission which the SecurityManager will check when code
that is running with a SecurityManager calls methods defined
in the management interface for the Java platform.
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 |
| control |
Ability to control the runtime characteristics of the Java virtual
machine, for example, setting the -verbose:gc and -verbose:class flag,
setting the threshold of a memory pool, and enabling and disabling
the thread contention monitoring support.
|
This allows an attacker to control the runtime characteristics
of the Java virtual machine and cause the system to misbehave.
|
| monitor |
Ability to retrieve runtime information about
the Java virtual machine such as thread
stack trace, a list of all loaded class names, and input arguments
to the Java virtual machine. |
This allows malicious code to monitor runtime information and
uncover vulnerabilities. |
Programmers do not normally create ManagementPermission objects directly.
Instead they are created by the security policy code based on reading
the security policy file.
