Security/safety today has to be global and subtle, which requires the consequences for the orientation of training to be taken on board. It is now essential to pass on detailed knowledge on the working of the various functions of a company (production, marketing, finance, communication, human resources, legal affairs, etc.) to allow security experts to suggest working arrangements that are compatible with the primary goal of any company: continual improvement of its financial results. It is also important for overall security systems to be seen as temporary arrangements that can always be improved. Lastly, security must chime with competitiveness, not only in the private sector but also in the public, the latter being a decisive actor in businesses’ security.
