Recently, new variants of Ransomware are becoming a new security issue. Ransomware continues to evolve to avoid network of security solutions and extort users' information to demand Bitcoin using social engineering technique. Ransomware is damaging to users not only in Korea but also in all around the world. In this thesis, it will present research solution to prevent and cope from damage by new variants Ransomware, by studying on the types and damage cases of Ransomware that cause social problems. Ransomware which introduced in this paper, is the most issued malicious code in 2016, so it will evolve to a new and more powerful Ransomware which security officers cannot predict to gain profit. In this thesis, it proposes 4 methods to prevent the damage from the new variants of Ransomware to minimize the damage and infection from Ransomware. Most importantly, if user infected from Ransomware, it is very hard to recover. Thus, it is important that users understand the basic security rules and effort to prevent them from infection.

The widespread use of the Internet brings about the issue regarding intellectual property and copyright. This paper describes DRM (Digital Rights Management) technologies and their related issues. Current approaches on DRM architecture are examined first. Based on the review, we discuss some security issues that would be essential to design security mood and architecture appropriate for DRM. Having these security issues in mind, we propose a new approach on DRM security architecture, based on our trust model.

Recently, The cloud computing technology is emerging as an important issue in the world, and In technology and services, has attracted much attention. However, the positive aspects of cloud computing unlike the includes several vulnerabilities. For this reason, the Hacking techniques according to the evolution of a variety of attacks and damages is expected. Therefore, this paper will be analyzed management models through case studies and experiments to the threats and vulnerabilities of the cloud computing. and In the future, this is expected to be utilized as a basis for the security design and performance improvement.

In January, 2005, "railroad security law" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad security issue, and each of railroad operative institutions accepted such situation that construct the integral railroad security system, resulting in constructing the emergent system coping with the railroad fire accident through the relevant study business to improve the railroad security efficiency against fire. This study tried to present the studying direction on developing the emergent educational program coping with the railroad fire accident, which is distributed to the spot, about the railroad worker for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedure of emergent system against the railroad fire accident.

Inernet of Things(IoT) is interaction with each other, collecting, sharing, and analysing the data. IoT has been noted in combining the fields of medical service in particular. However, the security issue is caused, while IoT is receiving attention. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. This study analyzes cases of leakage of personal medical information, security of IoT, privacy flow, and the response strategies.

As more users use mobile devices, shoulder surfing attacks have emerged as an important issue in security. According to research report, in fact, the result showed that about 30% of smartphone users are hit by shoulder surfing attacks. To this end, in this paper, we consider a shoulder surfing attack and propose a partially hidden password system to resistant to its attack. In order to help readers understand, we describe the proposed password system in more detail using one simple example. The core idea behind the proposed system is to place the user's password randomly in the specified grid instead of entering a password directly. As a result, even if an attacker makes a shoulder surfing attack to observe the password, the user can hide the preset password and defend against the attack. We also show how the security of the password system proposed in this paper is improved. In addition, even if there are consecutive shoulder surfing attacks, the security of the proposed password system is robust.

In this paper, we develop a Secure File Management Security(: SFMS) based on media in a cloud environment to encrypt and decrypt cloud data on a computer using a Bluetooth - based cryptographic module. The Bluetooth cipher module makes it easy to browse files stored in the cloud, but it is never possible to browse without a module. It is a solution that fundamentally blocks the problems such as hacking and leakage of personal data that have recently become an issue.

Traditional Cloud Computing would be unable to safely host IoT data due to its high latency as the number of IoT sensors and physical devices accommodated on the Internet grows by the day. Because of the difficulty of processing all IoT large data on Cloud facilities, there hasn't been enough research done on automating the security of all components in the IoT-Cloud ecosystem that deal with big data and real-time jobs. It's difficult, for example, to build an automatic, secure data transfer from the IoT layer to the cloud layer, which incorporates a large number of scattered devices. Addressing this issue this article presents an intelligent algorithm that deals with enhancing security aspects in IoT cloud ecosystem using butterfly optimization algorithm.

The article identifies areas for effective management of innovative development. The competitiveness of the economy in the context of European integration and economic security is assessed. The level of innovative economy of some countries of the world is analyzed. The issue of attracting foreign investors to stimulate innovative production in Ukraine is raised. It is identified the need for the formation of an updated state policy capable of providing innovative development and improving the competitive position of the state in international rankings. Emphasis is placed on the need to form a critical mass of managers-civil servants capable of developing, implementing and monitoring the policy of innovative development of entrepreneurship.

The issue "Exploring Social Media and Other Crucial Success Elements of Attitude towards Politics and Intention for Voting in Pakistan" is a huge study embracing more issues. The politics of Pakistan is basically the politics of semantic groups. Pakistan is a multilingual state more than six languages. There are 245 religious parties in Pakistan, as elaborated by the Daily Times research. The use of social media sites in Pakistan peaked to its maximum after announcement of election schedule by the Election Commission of Pakistan in March 22, 2013. Most of the political parties used it for the recent elections in Pakistan to promote their agenda and attract country's 80 million registered electors. This study was aiming to investigate the role of social media and other critical variables in the attitude towards politics and intention for voting.
