Apache Subversion (often abbreviated to SVN) helps software developers work together and maintain a complete history of their work.
Version Control System Goals:
Drupal is no doubt one of the best content management systems out there and is being used by thousands of sites across the world. The system is very secure but as soon as some security vulnerabilities are found it may be prone to attack/spam.

I recently had one of my Drupal sites hacked. The Drupal core wasn't up to date with its security patches and consequently it left the backdoor open, allowing a hacker to add malicious script to the Drupal core files.
This hack added a malicious script to Drupal’s core files namely index.php, .php and .js files inside themes directory etc.
