Use Drupal, other CMS or hand-made?

[Ashran]

Hi. I want make a webpage and I began it with drupal. I'm now learning it (it's a bit complicated, but i'm going on).
Now, I'm told that CMS have many security bugs such as SQL injection that are a real ****.

So... what should I do? I go on with my drupal project? I start something new?

Thanks guys!
