Cooperative Security Breaks the Limits of Traditional Security Measures

Just as broadband networking, high-performance and light-weight laptops and useful applications have significantly improved enterprise IT environments, the targets and complexities of security management have also tended to increase significantly. Actions against security problems are now required to be performed in no delay. The resulting movement of information and its carrying devices have produced many security issues that cannot be dealt with by a single, static security countermesure. In order to deal effectively with this situation, this paper proposes the notion of "cooperative security." Cooperative security allows security countermeasure utilities with different target domains to be mutually linked, thus achieving double or triple security management of the information and its carrying devices as well as maintaining a high security level for the enterprise. The new InfoCage series is a suite of utilities for implementing such management policies. It is also planned that "cooperative security" will be extended to the partner vendor products in order to enhance security linkages to the applications of other business fields such as paper documents and floor entrance/exit management systems, etc.
