Security information sharing platform over multiple services

It is necessary to protect services and users from diversified sources of cyber attacks even in complexly interconnected systems and networks. If a large number of smartphones in a mobile network are controlled by malware, they may be exploited to attack an application service in a fixed network. In this case, the conventional approach, which only protects the ingress and egress of services, cannot trace and identify those attacking smartphones in another network and the malware. To solve this problem, we propose a platform to share security information over multiple service infrastructures such as a fixed network, mobile network, and smartphone application market.
