Information About Java Applet Filtering
Java applets may pose security risks because they can contain code intended to attack hosts and servers
on a protected network. You can remove Java applets with the filter java command.
Note Use the filter activex command to remove Java applets that are embedded in <object> tags.
The filter java command filters out Java applets that return to the ASA from an outbound connection.
You still receive the HTML page, but the web page source for the applet is commented out so that the
applet cannot execute. The filter java command does not filter clientless SSL VPN traffic.
Licensing Requirements for Java Applet Filtering
The following table shows the licensing requirements for Java applet filtering:
