Like the other open source BSDs, the whole operating system is developed by the same group of people with OpenBSD. Programmes from other sources are available separately. OpenBSD is often the first to add new security tools to make it harder to break. Developers have also carefully read through the programming code to check for mistakes more than once. The project is led by [[Theo de Raadt]] from [[Calgary, Alberta]], [[Canada]]. There are few restrictions on people that use the source code, the [[BS
