Description
Java applications could contain malicious code; sites located in this security zone are more likely to be hosted by malicious individuals. This policy setting allows you to manage permissions for Java applets. If you enable this policy setting, options can be chosen from the drop-down box. Use of the Custom permission will control permissions settings individually. Use of the Low Safety permission enables applets to perform all operations. Use of the Medium Safety permission enables applets to run in their sandbox (an area in memory outside of which the program cannot make calls), plus adds capabilities like scratch space (a safe and secure storage area on the client computer) and a user-controlled file I/O. Use of the High Safety permission enables applets to run in their sandbox. If you disable this policy setting, Java applets cannot run. If you do not configure this policy setting, the permission is set to High Safety.
