Context-based remote security control for Mobile Communication Device

Recently, as smartphone is becoming more and more popular, concern about security threats against Mobile Communication Device (MCD) is getting higher. The MCD can not only become the target of the cyber attacks, but also be used as the tool of the cyber attacks. This paper proposes a context-based remote security control scheme for MCD. The proposed scheme consists of two systems: Context-based Mobile Security (CMS) client and server. The proposed scheme can automatically not only protect the MCD from cyber attacks, but also prevent the MCD from being used as an attack tool, by help of CMS server. As an additional advantage, the proposed scheme can maximize performance of the MCD in terms of computing resource efficiency and user convenience because it automatically manages the security of the MCD.

Design and Implementation of Mechanism for Effectively Exchanging Cybersecurity Information between Independent Security Management Domains

As a way for defending against cyber security threats, there has been a research on cybersecurity information exchange between security management domains in order to raise security performance of the whole network. One of the hottest issues in exchanging cybersecurity information between security management domains is that the requirements of those domains on information sharing are different with each other because each is autonomous domain. This paper proposes a mechanism for effective cybersecurity Information exchange between independent security management domains, which can satisfy their requirements on information sharing through sharing policy and sharing policy control protocol, proposed in this paper. In this paper we have developed an integrated security control system that supports the proposed mechanism. Through the system the performance of the proposed mechanism is measured and evaluated.
