Build my GPL3'd Signals Intelligence device, and you can audit it :)

- peter_d_sherman 7y agoDidn't know that that existed... Looks really nice!!! (Although, technically, to be really secure, you'd have to audit the entire RF spectrum AND lower frequency wavelengths, i.e., ultrasonic AND have to figure out what to do with signals that are intermittent and/or frequency hop!!! Then of course you have the power supply lines and the ability to send super-low frequency signals via all of that... In other words, you'd have to audit all wave frequencies from all connected devices, simultaneously, and keep in mind such possibilities as frequency hopping, and intermittent periods of silence... like if someone really wanted to be stealthy, they could send something like 1 byte per hour... and that hour is randomized, so it's actually a random interval between 50 and 70 minutes... and/or hide that in random radio noise... the possibilities are endless... <g> (This is why I leave security to the security people and just assume that no information is private anymore...)) But, all of that being said, your link looks really nice, and I didn't know that existed before! It looks cool and worthy of experimentation!
