How to manage your Java browser security

Have you ever seen the Java Console Panel icon in your task tray and wondered what it does and why you should update Java? Java is a programming language and is used by lots of applications. If you do not have Java, applications and websites will not work. If you don’t have Java installed on your PC you will need to visit the Java website:

Every new Java version contains important enhancements to improve performance, stability and security of the Java applications (and website browsing using JavaScript) that run on your machine. By installing the FREE update, you will ensure that your Java applications will run safely and efficiently.

Note: Java, which isn’t an application but a runtime environment, isn’t needed for every website you visit – some websites use it others don’t. You can disable Java if you so wish, but some websites you visit may still require Java to be enabled. I suggest you don’t disable Java but make sure it’s always up-to-date.

Some of my readers though have asked how do you remove the Java applets (used in web pages) which build up in the cache on your PC? Most cache cleaners do not clean the Java applets that are stored locally on your hard drive. Here are some simple steps using the Java Console Panel to delete your Java cache and improve your Java browsing security:

  • Go to the Control Panel (Windows only)
  • In Search Control Panel type “Java” and click the icon
  • On General TAB click ‘Settings’ on the Temporary Internet Files and ‘set the amount of disk space for storing temporary files’ to 500MB
  • Next on General TAB click ‘View’ and you will need to use the click down where it says ‘Show’ to highlight and delete the stored cache
  • Alternatively you can delete all of the stored cache from Temporary Internet Files – click ‘settings’ (as above) and click ‘Delete Files’

To improve your Java browsing security I suggest you consider using the Advanced option in the Java Console Panel:

Click on the Advanced TAB and click on ‘Security’ then ‘General’ and check the following:

  • Show site certificate from server even if it is valid
  • Check certificates for revocation using CRLs
  • Enable online certificate validation

For my more experienced readers:

Click on the Security TAB and click ‘Certificates’. Here you can manage the user and system trusted; secure site; Signer CA; Secure site CA; Client Authentication; as well as user-level and system-level certificates.

Safe surfing folks!

    Hmmm, it is very unlogic to me, these option to be disabled by default:
    – Check certificates for revocation using CRLs
    – Enable online certificate validation

    It ruins the whole Java application security 🙁
