This site (http://security.drupal.org) is used internally by the Drupal security team to coordinate their work, track issues and prepare security announcements. Here you can view the official list of Security Team members.

Announcements for Drupal itself as well as community contributed modules are posted by the team on Drupal.org along public service announcements.

If you need to contact the security team about a general issue use the Drupal.org contact form. We also have instructions for securely reporting a security issue.
