<div dir="ltr">I am going to begin by being rather unhelpful and saying all this will depend on how valuable access to your network will really be. If you are a giant tier one ISP, a bank, or even worse an intelligence agency, I doubt you would put the resale value of a device less than $100K higher than its ensured destruction (and that of it's contained data).<div>
<br></div><div>Being likely to be flash based / NVRAM, and most likely embedded into the device (otherwise you would simply keep the storage media) - you are going to have to be a pretty small player to be concerned about resale, yes?</div>
<div><br></div><div>And being a smaller player - who is really going to invest the time and materials required to make your life difficult for no other potential gain? To recover something you have overwritten by either making a false config you have copied nteenth times to fill and overwrite the storage - what is any sensible person going to be able to do with the hardware to bring back any kind of configuration data that can damage your network?</div>

I imagine this would be fun (For a few weeks at least) :D<br>
<br>
Another idea might be to look at a LOW level format which would flip the 0 and 1's numerous times, this is another good way of destroying data<br>

So at what point do you destroy and not sell.<br>
<br>
So I am thinking inbuilt cmos/flash in a closed box, I could write a file over the config file, but does that really work, you need multiple write over the same blocks on HDs. Do flash/cmos have the same issue.<br>
<br>
I am thinking about password for OSPF or BGP setups, all the per device password .... ie enable login die with the device..<br>
