Java Security Warning

If you are accessing Blackboard on a PC, you may receive a security warning when attempting to use certain features. The error reads:


“Java has discovered application components that could indicate a security concern.”

 

 

 

Solution

In the security dialog, if the user clicks Yes, it blocks potentially unsafe components from running, and the program may terminate. If the user clicks the No button, the application or applet continues execution.
Raising a warning is the default behavior, but there are options available for users to manage this situation.

You can manage how mixed code programs are handled through the Java Control Panel.

Find the Java Control Panel

Mixed Code Protection Options in the Java Control Panel

  1. In the Java Control Panel, click on the Advanced tab.
  2. Expand the Mixed code (Sandboxed Vs. trusted) security verification option under the Security section.

3. Choose from one of the following two options:

  • Enable – hide warning and run with protections: This will hide the warning message and cause Java to act every time as though you had clicked “No.”.
  • Disable verification: This will disable the new security feature altogether, with the risk that you could run potentially unsafe code without being warned.
