Applet Security
Local Applet Restrictions
When an applet is loaded from a local file system, instead of a network protocol, Web browsers and applet viewers may relax some, or even many, of the above restrictions. The reason for this is that local applets are assumed to be more trustworthy than anonymous applets from the network.
Intermediate applet security policies are also possible. For example, an applet viewer could be written that would place fewer restrictions on applets loaded from an internal corporate network than on those loaded from the Internet.
