What are the differences between mod_php and cgi and suphp

  1. What are the reasons of low security of mod_php?
  2. Is there any security problem in dedicated servers in which there exist only one user?
  3. How does mod_php cause security problems in shared servers?


  4. Is it right?

When cgi is used, web server delivers the requested file to cgi and cgi delivers the file to the PHP interpreter.


5. Why does `cgi` have better security than `mod_php?` Is this matter important in the dedicated server? 6. `Su_php` runs script under the user, what benefit can it have `su_php` with `mod_php` in a dedicated server with one user?
I have studied many articles and responses, but all of them have short answers and have not stated any details.:expressionless:
