I'm going to be buying a computer in the future here. I want to do an extreme local build I don't want anyway of allowing any type of transmissions to go in or out. 

 

I think the best way to go about this is wrapping it in some type of material to prevent any transmissions from being sent in or out. 

 

Does anyone know of a good material I could encase this system with or the best way to go about this? 

 

Basically I'm a writer and I would want something that has no chance or an extreme minimum to get any information sent in or out. 

 

Typewriters - too slow for me to type plus I enjoy fast corrections. Anything over 60 or 70 wpm doesn't seem to register properly. 

Paper - My handwriting would make a doctors look perfect plus I'm slow when I hand write.

If you are genuinely that concerned, you would need to consider peripherals as well, keyboard, screen... I'd suspect the only way might be to use the system in a cubicle that is a Faraday Cage.

You may find good reading if you use the keyword Tempest.

Thanks for the help. I'm going to build a faraday cage and play around with it.

Along with your writing activities, also consider having at least one if not two usb external pancake platter-clatter hard-drives, something similar to if not Macrium Reflect and/or Acronis True Image, having a weekly or bi-monthly routine of making at least one if not two full images of your OS and data partitions.  If your writings are going to be important, then restorable backups are going to be important.

Transmission?  Do you mean no external communication with the computer?  Why build a Faraday cage when you could simply disable the WLAN and LAN cards?

From the topic title and tone of posting, I believe w23 is thinking along the lines of:

Step 1, buy an unused missile silo in the midwest

Step 2, put computer at base

Step 3, close big metal door behind you

1. Disconnect from all wired and wireless network connections (Ethernet, Bluetooth, Infrared, Router, Wifi, Cable Satellite, Modem)
2. Remove all CD/DVD-ROM/DVD-RAM drives (and floppy disk/zip drive if you still have one).
3. Carefully super glue or expoxy shut ALL other connectors, especially Firewire/USB ports and Ethernet cable port. Advanced users can use high grade solder instead.
4. Hide the computer in an safe place where no other users have access,

quietman7, your tip #3, superglue, epoxy or silicone is a better alternative than solder.  Solder is conductive by design, almost all external connectors on a PC have both power and ground and connecting power and ground with conductive material is like crossing the streams (Ghostbusters reference).

What ? ...no comment on a UPS for power outages ?..Loss of Data.

 

And Agree with mremski..

Step 2, put computer at base

Step 3, close big metal door behind you

 Maybe a Security Gaurd  24/7 against Theft.

Thanks for the tips. 

 

All I needed was a faraday cage for now and to test it to make sure it works. I will disable whatever I can alongside that. 

 

I figure just back up what I can afford to lose. If I can afford to lose four hours of work then that's the way to do it. Figure back up once a day after I'm done. 

 

Got kali linux running and everything is up at this point. Just waiting on the faraday cage parts to arrive then build and test it out.

 

Kali Linux - high security

Faraday Cage - extra security

 

Just want to write like I'm writing on paper and not deal with anything else.

You might also want to perform a system image every so often.
