Internet Security Tip: Lock Your Doors! By Disabling Java Plug-in

Security Key purpleEffective Internet security practices are much like securing our houses from burglars or other intruders. At a minimum, we must lock our doors and windows to keep the bad guys out. Securing our computers involves locking our “doors and windows” by applying updates to vulnerable software and deleting or disabling unnecessary software that may be a probable “entry point” to our house…er, computer.

One of the ways we can improve our security is to disable the Java Plug-in. It’s used to provide interactive features to web applications that cannot be provided by HTML alone. It can capture mouse input (like rotating a 3D object) and also have controls like buttons or check boxes. These are useful tasks it performs, but the problem is that it’s also a huge target right now for malware attacks. That’s an open door to your house. Not all software applications use Java plug-ins, in fact, relatively few do, so disabling it and avoiding the threat of malware attack, in my opinion, outweighs the possibility that you may need to temporarily enable it once in a while to run a software application that needs it.

Mary Landesman at Mary’s Antivirus Software Blog recently explained how to disable the Java plug-in for Internet Explorer and Firefox browsers. It’s really pretty simple to do. Check out her post and then close and lock that door by disabling Java plug-in.

  2. Paul,

    Java is actually very innovative in terms of development and engineering; however, it is one of those things that is good, but is bad (in terms of computer security). Really is too bad it leaves an open avenue for trouble. As usual, a very professional post.


    • Rick,
      I agree wholeheartedly, Java is not the culprit here. Like Windows, it’s popularity makes it a target for malware. Thanks for reminding us about that. …and I sure appreciate you stopping by.

    Hey Paul,

    I have the ultimate answer. I don’t have Java installed, at all. I don’t need it, and I don’t like it. Problem solved lol.


  4. Absolutely agree Paul.

    I would never allow Java, or JavaScript to run unattended on my computer. Which is why a user with any experience will run NoScript in Firefox, or turn off Java in IE.

    The whole idea is that the user remain in control – not the web site. Seems like a no-brainer to me.



    • Bill,
      As usual, an excellent comment. You’re right in that folks with experience will be very cautious with Java and JavaScript; however, many users aren’t experienced…that’s our cross to bear as educators, I guess. I really like your statement “the whole idea is that the user remain in control”. That would make our jobs easier; and the Internet a better place.
      Thanks for the thoughtful, experienced comment, and for stopping by my humble blog.

  5. Paul,

    but once we will disable the java plugin most of the sites will stop working as they need java to be enabled in the browser
