The Pro version of Articles Anywhere offers advanced Security Control over who can use the extension and where it can be used.
These settings can be useful on websites where multiple people have rights to create and publish content.
You can control in which components or areas of the site Articles Anywhere should be enabled, and which User Groups are allowed to use it.
The advice is to not allow the usage in components where non-backend users can post content. For instance in forums and message boards.
See the "Security Options" tab in the Articles Anywhere system plugin settings for all the different settings
