<![CDATA[Security and frozen modules]]>Through the REPL, is it possible to get access to frozen modules and boot-loaded firmware if it is not encrypted? Or does one only have access to the scripts and the high level files?

And if not through the REPL/FTP, how difficult is it to get access to the firmware? I am trying to weigh out how important secure boot/encryption is vs just using frozen modules as a security barrier.

Thanks
