root does also have access to a remote link. so does the attacker. the
linux system doesn't have any mean of whom exactly is changing the
cdrom. there's an abstraction layer to identify you with, typically, a
password in the system. this stuff is stored on easy-to-modificate
media. you must have a proection in the kernel in a secure environment
and even then it's not secure.
