JavaScript Security - Because JavaScript is downloaded from an
unknown origin and executed on your computer, JavaScript has the potential of being a virus
or doing other malicious things to your computer. To address this issue, Sun implemented
tight security features from the earlier stages of Java development. These features
include verification of byte codes (to ensure they don't violate access restrictions and
more), as well as configurable network security that ranges from disabling network access
to limiting access by an applet only to the host where the code originated, all the way to
completely free network access.
