About Flash Player security settings

Adobe has designed Flash Player to provide security settings that do not require you to explicitly allow or deny access in most situations. You might occasionally encounter legacy Flash content that was created using older security rules for Flash Player 7 or earlier. In these cases, Flash Player lets you allow the content to work as the developer intended, using the older security rules; or, you can choose to enforce the newer, stricter rules. The latter choice ensures that you only view or play content that meets the most recent standards of security, but it may sometimes prevent older Flash content from working properly.

All users who view SWF files (including non-Flash developers) can set permissions globally through the Global Security Settings panel in Flash Player Settings Manager (shown in the following figure).

When older content runs in a newer version of the player, and Flash Player needs you to make a decision about enforcing newer rules or not, you may see one of the following pop-up dialog boxes. These dialog boxes ask your permission before allowing the older Flash content to communicate with other locations on the Internet:

  • A dialog box might appear alerting you that the Flash content you are using is trying to use older security rules to access information from a site outside its own domain, and that information might be shared between two sites. Flash Player asks if you want to allow or deny such access.

    In addition to responding to the dialog box, you can use the Global Security Settings panel to specify whether Flash Player should always ask for your permission, through the dialog box, before allowing access; always deny access, without asking first; or always allow access to other sites or domains without asking your permission.

  • (Flash Player 8 and later) A dialog box might appear alerting you that a SWF file is trying to communicate with the Internet. Flash Player doesn't let local Flash content communicate with the Internet, by default.

    Click Settings to access the Global Security Settings panel, where you can specify that certain Flash applications on your computer may communicate with the Internet.

To change your security settings or learn more about your options, you use the Global Security Settings panel. Use this panel to reset the privacy settings in Adobe Flash Player:

  • If you select Always Deny and then confirm your selection, any website that tries to use your camera or microphone is denied access. You are not asked again whether a website can use your camera or microphone. This action applies both to websites you have already visited and to those you haven't yet visited.
  • If you select Always Ask and then confirm your selection, any website that tries to use your camera or microphone must ask your permission. This action applies both to websites you have already visited and to those you haven't yet visited.

If you previously selected Remember in the Privacy Settings panel (see the following figure) to permanently allow or deny access for one or more websites, selecting Always Ask or Always Deny has the effect of deselecting Remember for all those websites. In other words, the selection you make here overrides any previous selections you may have made in the Privacy Settings panel, shown in the following figure.

After you select either Always Ask or Always Deny (or instead of doing so), you can specify privacy settings for individual websites that you have already visited. For example, you might select Always Deny here, then use the Website Privacy Settings panel and select Always Allow for individual websites that you know and trust.

For locally deployed content and local data, users have another option: They can specify which SWF files may access the Internet using the Global Security Settings panel. For more information on specifying settings in the Global Security Settings panel, see Specifying trusted files using the Settings Manager.

NOTE

 

The selections users make in the Global Security Settings panel override any decisions made in the security pop-up dialog box.
