I found this post while i am surfing,As this looks extremely good i decided to post here
Everything can be hacked!
That’s a quote I love, you hear it all over the net. Most people reversing software/hardware or people penetrating highly secure (or at least claimed) networks, state that most of today’s applications/hardware/networks can be compromised. Normally you see the vicious circle of stuff being released….hackers attempting to pwn it, vendors claiming it can’t be hacked, hackers publishing the hack. I might be exaggerating a little bit, but usually that’s the general consensus. Of course there are exceptions to the rule and there is hardware/software out there that hasn’t be hacked yet and maybe it really is NOT hackable. Today I wanted to write about one of those exceptions
This post will cover the devices and answer the question if I believe their 100% claim, it will also cover some of my midnight thoughts on how to use alternative ways to maybe get data back even when such a device is in place. These ideas DO NOT BYPASS the device, so don’t get your hopes up, it are just possible ideas to use other vectors instead of routing your traffic through the secure device.
Bold claims, the network is still vulnerable from attack. The theory is amazing, but in practice the information is still being passed from one point, to the diode, then into the secure area. So before it hits the diode it's still vulnerable classified data.
The branding of having the diode's installed alone will surely send the price of hardware and networking on this level through the roof, making it too expensive for smaller companies or the average joe to implement the solution...
