Creating secure applications

Dishonest users might try to hack your application, whether you build a small portal site where users can log in and read articles or a large e‑commerce store. For this reason, consider the following steps to secure your application.

• Post data to HTTPS for data that needs to be secured. Encrypt values in Flash before sending them to a remote server to be processed.

  Important: Never store any information or code in a SWF file that you don't want users to see. It is easy to disassemble SWF files and view their contents using third-party software.

• Add a cross-domain policy, which prevents unauthorized domains from accessing your assets.
