Oracle Revises Java: Prevent Apps from Running in Browsers + How to

The latest Java release, update 10 on December 11, allows users to restrict Java from running in web browsers. The newest version of the Java Development Kit, JDK 7 update 10, provides the ability to prevent any Java application from running in the browser. Since Java has been subject to so many security vulnerabilities and other miscellaneous attacks, this was the best move by Oracle.

It includes a good amount of security enhancements also, including the ability to set a specific level of security for any unsigned Java applets.

Some of the exploits seen in the past have made it clear that this was needed also for the unsigned Java applets. It calls for more default deny technology, which restricts quite a bit of features, but includes greater security.

That’s the biggest problem in applications and operating systems, is that developers do not want to suppress the features so much, but also don’t want a bunch of security threats. So, finding that balance is very important.

Allowing these new enhancements for the security of Java will help prevent a slew of Java attacks and keep people from turning away from Java. Most people will try to find alternatives if a plugin keeps getting attacked, e.g. Foxit Reader or Nitro Reader replacing Adobe Reader.

“The ability to select the desired level of security for unsigned applets, Java Web Start applications, and embedded JavaFX applications that run in a browser. Four levels of security are supported. This feature can be set in the Java Control Panel or (on Microsoft Windows platform only) using a command-line install argument,” Oracle said.

The final security feature released includes the ability to warn the user when the Runtime Environment (JRE) is out of date or below security standards.


How to enable this feature:

  • Go to the Control Panel.
  • Find the Java icon and double-click on it.
  • Click the Security tab.
  • Uncheck “enable Java content in the browser”.
