LinkPermission

public final class LinkPermission
extends BasicPermission

java.lang.Object
↳	java.security.Permission
	↳	java.security.BasicPermission
		↳	java.nio.file.LinkPermission

The Permission class for link creation operations.

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

hard Ability to add an existing file to a directory. This is sometimes known as creating a link, or hard link. Extreme care should be taken when granting this permission. It allows linking to any file or directory in the file system thus allowing the attacker access to all files.

symbolic Ability to create symbolic links. Extreme care should be taken when granting this permission. It allows linking to any file or directory in the file system thus allowing the attacker to access to all files.
