A common concern about Free Drupal Themes or any open-source product is whether or not it is secure. The fact is, in general, open-source software is as secure or more secure than proprietary, commercial software. The increased security of using open-source is cited as one of the reasons that the White House site switched to Drupal. Free Drupal themes ensure the security of your work like no other.
The reality with any piece of software is that all code has bugs (including security bugs). And the most important thing is to have an active group of coders and researchers finding and fixing bugs. Drupal has amassed a large community of web developers over its now 10-year lifetime who the source of reports made about bugs in Drupal. Any security bugs reported by Drupal’s community are examined by Drupal’s dedicated Security Team. When a bug fixed, this same Security Team evaluates the fix to confirm that the issue resolved. This is applicable to contributed modules as well as Drupal’s core.
When a security bug confirmed in a contributed module, the developer who maintains that particular module contacted about the bug and given a deadline. Failure to fix a security bug will result in the module being unpublished on Responsive Drupal’s site. Nodes are typically where you will find the main content of a site. You can think of them simply as pages of your website. In their simplest form, nodes contain a Title and a Body.
