This policy setting allows you to manage permissions for Java applets. If you enable this
policy setting, you can choose options from the drop-down box. Set to Custom to control
permissions settings individually. Low Safety enables applets to perform all
operations. Medium Safety enables applets to run in their sandbox (an area in memory
outside of which the program cannot make calls), plus capabilities like scratch space (a safe
and secure storage area on the client computer) and user-controlled file I/O. High Safety
enables applets to run in their sandbox. Disable Java to prevent any applets from
running. If you disable this policy setting, Java applets cannot run. If you do not configure
this policy setting, Java applets are disabled. The recommended state for this setting is-
