Managing Java on your computer

Installing & Updating Java

Please read this important advisory

On 1/10/13 the Department of Homeland Security issued an alert recommending that all Internet users "consider disabling Java in web browsers until adequate updates are available" due to recently discovered security flaws in the software. Although Oracle (publisher of Java) regularly issues security patches (and has patched the flaw(s) announced on 1/10/13), Java remains a favorite target of hackers.

  • Java is active by default on most computers.  Consequently, it  is vital that you always keep it up-to-date.  This applies to your office and home computers alike.  Even if you disable Java, it is important to keep it up-to-date in the event you discover a (trusted) web page or program that requires it.  Then, if you must enable it for a one-time use, you'll have the most secure version already installed.
  • Typically mobile devices (smart phones, tablets) do not have Java installed.  If you deliberately installed Java on your mobile device, you should also keep it up-to-date. 

NOTE: Java is not the same thing as JavaScript. You can leave JavaScript alone.
