@Exported public final class AttachPermission extends BasicPermission
SecurityManager set, this
is the permission which will be checked when code invokes VirtalMachine.attach to attach to a target virtual
machine.
This permission is also checked when an AttachProvider is created.
An AttachPermission 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 |
|---|---|---|
| attachVirtualMachine | Ability to attach to another Java virtual machine and load agents into that VM. | This allows an attacker to control the target VM which can potentially cause it to misbehave. |
| createAttachProvider | Ability to create an AttachProvider instance.
|
This allows an attacker to create an AttachProvider which can potentially be used to attach to other Java virtual machines. |
Programmers do not normally create AttachPermission objects directly. Instead they are created by the security policy code based on reading the security policy file.
