Security covers the whole spectrum of activities that contribute to lower the impact of risks and threats. For enterprises as well as for collectivities, technology has become the only way to face the growing complexity that goes along with globalization of exchanges and exposure to international threats. On the physical standpoint, videosurveillance emerges as the best substitute to human presence to ensure observation, surveillance and intelligence missions. On the logical standpoint, supervision and intrusion detection have become the indispensible complements of the classic firewall.

But the race for security reaches another milestone when one realizes that the security management systems are themselves information systems that must be protected, even before the resources that they watch after. This way, access control and identity management are the cornerstones, the foundations of all the security infrastructure, logical as well as physical.
