Is it possible to secure swf files?

1- Obfuscate your ActionScript using an advanced obfuscator such as secureSWF.

2- Domain lock your SWF files.

3- Create a dummy loader, rename the original SWF files and change their extension, then load the original SWF files using the dummy loader.

4- Make sure to prevent hot linking. (this will depend on your web server)

5- Encrypt sensitive strings in your ActionScript; either manually in your code, or you can also use secureSWF for that.
