do you know the level of security they put their code through? Especially for mission critical systems? Most of us programmers take for granted libraries and COTS products that we find online when we have little idea who coded them and if they put backdoors in them. Most programmers have no idea security of their systems especially if most are put together as fast a humanly possible. Simply put ... you cannot use COTS&#x2F;Open Source for warefare systems. There is a reason the military now considers battles spaces land, sea, air, and cyberspace.
