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.

If one analyzes recent cyber incidents including personal information infringement cases, it seems like actual attack is targeting Internet service providers but actually they are targeting Internet service users. For many users, all the services were not provided to them as they have signed for in the contract or personal informations, which users have provided to service providers when signing contracts, were disclosed to public without users' consent causing aftereffect. As a result, importance of S-SLA indexes, which is to be included in the SLA to be signed between a user and a service provider, is ever more increasing. Especially, if there is a S-SLA indexes for anti-virus services, service providers have to provide a high quality of service as they have signed in the SLA. However, there wasn't any researches in the S-SLA area domestically and there are only limited SLA indexes related to system or service maintenances at the moment. Therefore, this paper analyses security functions in anti-virus services and proposes S-SLA indexes for different security level.

Security vulnerability quantification is the method that identify potential vulnerabilities by scoring vulnerabilities themselves and their countermeasures. However, due to the structural feature of smart grid system, it is difficult to apply existing security threat evaluation schemes. In this paper, we propose a network model to evaluate smartgrid security threat for AMI and derive attack scenarios. Additionally, we show that the result of security threat evaluation for proposed network model and attack scenario by applying MTTC scheme.

According to the NIS, damages due to leaking industrial technology are reaching tens of trillion won. The type of damages are classified according to insider leaks, joint research, and hacking, illegal technology leaks and collaborated camouflaged. But 80% of them turned out to be an insider leak about connecting with physical security. The convergence of IT and non IT is accelerating, and the boundaries between all area are crumbling. Information Security Industry has grown continuously focusing Private Information Security which is gradually expanding to Knowledge Information Security Industry, but Information Security Industry hereafter is concentrated with convergence of IT Security Technology and product, convergence of IT Security and Physical Security, and IT convergence Industry Security. In this paper, for preventing company information leaks, logical security and physical security both of them are managed at the same level. In particular, using convergence of physical security systems (access control systems, video security systems, and others) and IT integrated security control system, convergence security monitoring model is proposed that is the prevention of external attacks and insider leaks, blocked and how to maximize the synergy effect of the analysis.

The information space, the main components of which are information resources, means of information interaction, and information infrastructure, is a sphere of modern social life in which information communications play a leading role. The objective process is the gradual but stable entry of the national information space into the European and world information sphere, in the context of which there is a legitimate question of its protection as one of the components of the national security of Ukraine. However, the implementation of this issue in practice immediately faces the need to respect the rights and fundamental freedoms guaranteed by international regulations and the Constitution of Ukraine, especially in the field of cybersecurity. The peculiarity of the modern economy is related to its informational nature, which affects the sharp increase in cyber incidents in the field of information security, which is widespread and threatening and affects a wide range of private, corporate, and public interests. The problem of forming an effective information security system is exacerbated by the spread of cybercrime as a leading threat to information security both in Ukraine and around the world. The purpose of this study is to analyze the state of cybersecurity and on this basis to identify new areas of the fight against cybercrime in Ukraine. Methods: the study is based on an extensive regulatory framework, which primarily consists of regulatory acts of Ukraine. The main methods were inductions and deductions, generalizations, statistical, comparative, and system-structural analysis, grouping, descriptive statistics, interstate comparisons, and graphical methods. Results. It is noted that a very important component of Ukraine's national security is the concept of "information terrorism", which includes cyberterrorism and media terrorism that will require its introduction into the law. An assessment of the state of cybersecurity in Ukraine is given. Based on the trend analysis, further growth of cybercrimes was predicted, and ABC analysis showed the existence of problems in the field of security of payment systems. Insufficient accounting of cybercrime and the absence in the current legislation of all relevant components of cybersecurity does not allow the definition of a holistic system of counteraction. Therefore, the proposed new legal norms in the field of information security take into account modern research in the field of promising areas of information technology development and the latest algorithms for creating media content.

The advent of the Internet of Things (IoT) technology, which brings many benefits to our lives, has resulted in numerous IoT devices in many parts of our living environment. However, to adapt to the rapid changes in the IoT market, numerous IoT devices were widely deployed without implementing security by design at the time of development. As a result, malicious attackers have targeted IoT devices, and IoT devices lacking security features have been compromised by attackers, resulting in many security incidents. In particular, an attacker can take control of an IoT device, such as Mirai Botnet, that has insufficient security features. The IoT device can be used to paralyze numerous websites by performing a DDoS attack against a DNS service provider. Therefore, this study proposes a scheme to minimize security vulnerabilities and threats in IoT devices to improve the security of the IoT service environment.

We introduce a novel high-level security metrics objective taxonomization model for software- intensive systems. The model systematizes and organizes security metrics development activities. It focuses on the security level and security performance of technical systems while taking into account the alignment of metrics objectives with different business and other management goals. The model emphasizes the roles of security-enforcing mechanisms, the overall security quality of the system under investigation, and secure system lifecycle, project and business management. Security correctness, effectiveness and efficiency are seen as the fundamental measurement objectives, determining the directions for more detailed security metrics development. Integration of the proposed model with riskdriven security metrics development approaches is also discussed.

Smart environment of health information technology, u-Healthcare architecture, ad-hoc networking and wireless communications environment are major factors that increase vulnerability of u-healthcare information systems. Traffic domain is the concept of network route that identifies the u-Healthcare information systems area as the traffic passing and security technologies application. The criterion of division is an area requiring the application of security technology. u-Healthcare information system domains are derived from the intranet section. the public switched network infrastructure, and networking sectors. Domains of health information systems are separated by domain vulnerability reason. In this study, domain-specific security vulnerability assessment system based on the USN in u-Healthcare system is derived. The model used in this study suggests how to establish more effective measurement USN-based health information network security vulnerability which has been vague until now.
