The Cloud Computing is growing rapidly in the current IT industry. Cloud computing has become a buzzword in relation to Grid & Utility computing. It provides on demand services to customers and customers will pay for what they get. Various "Cloud Service Provider" such as Microsoft Azure, Google Web Services etc. enables the users to access the cloud in cost effective manner. However, security, privacy and integrity of data is a major concern. In this paper various security challenges have been identified and the survey briefs the comprehensive overview of various security issues in cloud computing. The classification of security issues in cloud computing have been studied. In this paper we have discussed security challenges in cloud computing and also list recommended methods available for addressing them in the literature.

Internet of Things (IoT) is now spreading everywhere. It's the technology of every person's need so we can't step back from IoT but we can secure it as it is spreading quickly so it has greater chances of danger and being misused. There is an urgent need to make IoT devices secure from getting cracked or hacked. A lot of methods had tried and still trying to mitigate IoT security issues. In this paper Blockchain is going to be the solution of most of the IoT issues or problems. We have discussed or highlighted security issues with centralized IoT and then provided solution of such security challenges through the use of blockchain because is based on a decentralized technology that is hard to modify or update.

In the data economy era, various policies are being implemented to create an active data distribution environment. In South Korea, the formation of a big data distribution platform and data trading began with the launch of the Financial Data Exchange under public data governance. In the case of major advanced countries in the data field, they have built a data distribution environment based on the data broker industry for decades and have strengthened national data competitiveness through added values generated from the industry. However, behind the active data distribution through data brokers, there are numerous information security issues, which have resulted in various privacy issues and national security threats. These problems can occur sufficiently in the process of domestic financial data exchange. In our study, we analyzed various information security issues of data trading caused by data brokers and derived information security requirements to be considered when trading data. We verified whether information security requirements are well reflected in the information security policy for each transaction stage of the domestic financial data exchange. Based on the verification, measurements to strengthen information security for financial data exchange are presented in our paper.

The importance of communication security is increased in the power industry. The representative communication network of power industry is the SCADA(Supervisory Control and Data Acquisition) systems. The SCADA system has been used for remote measurement and control in the power industry. Recently, many studies of SCADA network security have been carried out around the world. In this paper, we introduce recent security issues in the SCADA network and propose the application of a symmetric encryption method to the Korea SCADA network.

RFID security and privacy issues have been intensively studied in the research field, the authentication between RFID reader and tag is the fundamental them. Most of the existing authentication protocols draw assumptions on classic primitives. Since tags have small capacities, the security mechanisms which are in use in computer networks and communication are not suitable. In this paper, we compare and analyze recent technical research on the problems of privacy and security. It consists of security mechanism, threats and performance evaluation, etc.

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.

Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its read. Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its reader. This paper will approach consideration of security analysis with cryptographic primitive based on hardware basis.

A mobile agent system is an infrastructure that supports the mobile agent paradigm. The main challenges encountered in designing this infrastructure are discussed in this paper. After introducing a generic mobile agent system, we discuss the design issues at two levels. System level issues like the provision of agent mobility and security, are mainly encountered in developing the runtime environments for agent execution. Language level issues, such as agent programming models and primitives, arise in providing support for mobile agent programming, mainly at the library level. This paper Identifies such system and language-level issues, and illustrates the different ways developers ate addressing them. We outline the specific challenges addressed by this dissertation, primarily in the area of mobile agent security.

Despite much discussions on cyber-terrorism in South Korea, several missing issues could be addressed. This paper attempts to deal with such missing but important issues. In South Korea, there has been little attentions on cyber-terrorism with the respects of national security strategy development under macro framework responding to future security environment. This article focuses on such issues. In other words, the purpose of this paper evaluates the meaning of national security threats raised from cyber-terrorism as a mode of security threats and proposes the matter of cyber-terrorism within the development of national security strategy in the future security environment. several issues in this discussion pass some important messages for the construction of national security strategic approach framework within the future security environment adding cyber-space. in the future environment, a new space called cyber is added as an important external condition which might determine the security of individuals, societies, and nations. Therefore, the fundamental strategic framework should be prepared. After that, the trend and direction of future technological advancement should be understood and the identity, nature, and types of threat should be analyzed. Also, after that, various responses and countermeasures are together constituted in the aspect of function and system regarding various anticipated threats of the future human society including cyber-terrorism.

Security and privacy issues complicate wireless local area network deployment. for a wired network, certain levels of security are maintained since access to the physical medium is restricted to the devices physically connected to the network. Though wireless local area networks offer some built-in security features, security breaches are possible if appropriate precautions are not taken. This paper describes security issues related to wireless local area networks and presents a software approach for restricting and controlling wireless access. The system authenticates users on the basis of identity, privileges and access hardware by distributed software agents that implement security policy and restrict unauthorized access.
