How to disable Java in browsers and system homeland security alert howto

January 12, 2013

In response to a Homeland security alert released today I wanted to quickly post on how to disable java or remove it if you are super cautious. Because homeland security alert news did not do two important things

1. tell you how to protect yourself.

2. what is the actual issue: who dafuq are the so called security experts and why is it not critical to mention source as well details of the said exploit.

On windows you can uninstall Java from the control panel and reboot.

If you just want to disable browsers you can do so in Chrome by going to Options menu -> Settings tab -> Under Privacy click “Content Settings” Button. In the following popup you will see a Plugins section. Select “disable individual plug-ins”. A new chrome page will lload with the long list of plugins you have installed.  Disable Java (TM) from here.

On Firefox, Java is usually disabled. But just in case you want to verify it is much easier. Click the Firefox menu -> Select “Add Ons” and then the “Plugins” tab in the following screen. You can disable Java from here. Additionally Firefox will disable other known vulnerable plugins so if you find those in Chrome you might as well disable them there.

You may also want to disable the “java deployment toolkit” or anything that references Java. Though I am not certain if this is safest and therefore recommend uninstalling Java. The reason being that a lot of 3rd party plugins do integrate Java technology within itself. Your choice.

Internet Explorer. You may want to “try” and uninstall that.

Additionally. I recommend disabling or removing “Adobe Reader” plugins as it is the second most vulnerable as reported by “security experts”. For all we know this is just another industry play at screwing with the most prominent Browser plugin and the Android platforms being as omnipresent as they are , are also based on Java software.

The best thing to do is check extension/plugins or addons on your browsers regularly and disable those that seem to be unused or you cannot recall why they are there. Unused and low quality 3rd party plugins are actually much bigger threat as they most likely developed by organizations without much security auditing and do not see security maintenance regularly if at all. Remove them if you can.
