NAS Device on DMZ Security

[twwong]

   

I'm considering having my Linkstation Live on the DMZ of my router (so that I can get to it from the Internet).  Does anyone have any knowledge as to how secure it is to do this?

 

It is my understanding that the Linkstation Live runs a variant of the Linux OS.  How secure is this on the Internet?  Assume all of my folders on the NAS are username and password protected (except the Info folder that is created by Buffalo).

 

Thanks...Titus
