Now that more and more computers and other devices are hooked up to insecure networks, security has become a very important issue. The word "security" can have many meanings, but in a computer context, it generally means preventing unauthorized people from making your computer do things that you don't want it to do.
There are vast tracts of security information in books and on the Internet. This chapter provides a very brief introduction to the subject of security, points you toward outside information and resources, and discusses security issues that are unique to QNX Neutrino.
