Maintain an allow list of trusted content packagers
An allow list is a list of trusted entities. In the case of content packagers, these are organizations trusted by the content owner to package (or encrypt) the FLV/F4V video files, creating DRM protected content. When deploying Adobe Access, it is recommended that you maintain an allow list of trusted content packagers, and that you verify the identity of the content packager contained in the DRM metadata (the DRM header) of a DRM protected file prior to issuing a license.
To learn more about obtaining information about the entity that packaged the content, see V2ContentMetaData.getPackagerInfo() in the Adobe Access API Reference .
