The problem of security starts with the elucidation of a paradox: the need for a secure space that is closed in on itself, whereas that need is more acute and pertinent within a company culture which is completely open and modernised. Security for us does not mean blocking information flow and exchanges, but making them possible and long-lasting by organising them. Lasting development (in its non-ecological sense) implies protection, reducing the gravity and the occurrence of risks.

The task of training in this domain thus assumes quite another aspect. The first requirement is for the right people; security and safety call for high-grade staff. Security is not just a question of physical guards. Risks and threats are both more diffuse and more varied than they were at the beginning of the 1990s. It has become essential to think about the vulnerabilities of any organisation in a systematic way, anticipating and abstracting as much as possible. Naturally, this goes with a preservation of and increase in operational capability, and even the resolution of the crises which tend to become recurrent situations for many actors, both institutional and private.

Security training further implies the acceptance of a significant effort (in terms of apprenticeship) in the search for cross-disciplinary activity, the pooling of knowledge and the comparison of experiences and expertise. Without being in any way exhaustive, the list of skills and theoretical knowledge needed for the security and safety function is massive:
