Overview—Applet Security Model

Basic Security Model

Java^TM Plug-in supports the Java 2 SDK, Standard Edition v 1.4 security model. This means that:

• All applets are run under the standard applet security manager. This prevents untrusted applets from performing potentially dangerous operations, such as reading local files. See the Java Security FAQ for details on the restrictions on applets.
• Signed applets are allowed full access to the local system. See Deploying RSA Signed Applets for details on how to use signed applets with Java Plug-in.
