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.
