Securing temporary buildings can be a tricky task. Generally buildings of this nature, while on a private site do not benefit from the security of the site itself, because they are geographically detached from the main site.

This is an issue, because assuming your site has a security system installed, it will be designed to secure buildings that were there when the system was being designed and temporary structures have been added at a later time to the existing area.

Temporary structures can in fact reduce the security of the site. Large structural additions to the site can act as cover for approaching intruders and may provide a protected route around the site.

The best way to secure the site is to consider and design the security system after the temporary buildings have been installed. If this is not possible then make allowances for temporary buildings if you think they may be used in he future.
