Regardless, the research being accomplished by federally-funded projects dealing with the issues of computer security are escalating. I've personally joined and examined many such conferences and have carefully examined the issues. Many of these issues will become future Phrack articles which I'll write. Others, such as limited-life semiconductors and deliberate telephone line noise sabotage caused by ACK packet detections in order to drive telecommunication costs higher, are sadly unpreventable problems of the future which won't be cured by simple awareness of the problem. Scores of other groups exist for every network, even every operating system.
Encryption stands in the way.
Computer Security is literally so VAST a concept that, once a person awakens to low-level computer mechanics, it becomes nearly impossible to prevent that person from gaining unauthorized access to machines. Because of the ease of breaking through security, it becomes very difficult to actually create an effective way to protect yourself from any form of computer hacking. Furthermore, totally non-CPU related attacks are taking place. I've memorized so many ways to bypass computer security that I can rattle them off in pyramid levels. If a computer is not even connected to a network or phone line, people can watch every keystroke typed and everything displayed on the screen.
