RMI wants you to provide a security manager for all RMI servers; for RMI servers that load client classes, a security manager is required. There is a default RMI security manager that you may use for this purpose, or you may write your own.

In a customized browser

If you’re writing your own Java-enabled browser, you’ll want to provide a security manager. In addition, if you’re using an existing browser, you may want to use a different security manager in that browser. Some browsers already allow the user to specify a different security manager via a property; other browsers can be licensed for this type of customization.
