com.sun.tools.attach.AttachPermission
- All Implemented Interfaces:
- Serializable,- Guard
When a 
 
 
 
SecurityManager set, this
 is the permission which will be checked when code invokes VirtualMachine.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 AttachProviderinstance. | 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.
