Enterprise security management system: Enterprise Security Management (EMS) is centralized integrated management of other kind of security solutions such as intrusion cutoff system, intrusion detection system and virtual private network. With the system, it is possible to establish security policies for entire IT system through interlocking of solutions. A security system of company network is progressing as a ESM(Enterprise Security Management) in existing security solution foundation. The establishment of the security policy is occupying very important area in ESM of the security system. We tried to analyze existing ESM system for this and designed security solution structure for enhancing the inside security. We applied implementing directly IDS system and tested. This test set the focus about inside security

Grid system is based on the Grid Security Infrastructure (GSI). GSI uses user's proxy to guarantee availability among multi-trust domains. Since grid system has been developed focusing on availability, GSI provides authentication and authorization performed by systems, but there are lacks of privacy consideration. For this reason, some researchers decide to use their own cluster system and do not want to use public grid systems. In this paper, we introduce a new privacy enhanced security mechanism for grid systems. With this mechanism, user can participate in resource allocation and authorization to user's contents more actively. This mechanism does not need to change previous middleware and minimize the computational overheads.

Is caused by with growth etc. of the digital contents circulation market which leads suddenly accommodates in order to control the network traffic which increases and the researches which are various are being advanced the explosive evidence and a electronic transaction of the Internet user. The present paper protects a digital contents and a copyright from CDN system environments which will appear the center of new network service with the plan for the dispersive DRM system of CDN bases plans. Respect this dispersion DRM package formats which provide a stronger security characteristic in the contents which is stored the operational process of the dispersive DRM system for to be defined, CDN system and of existing interoperability they present.

Current internet has evolved from the sharing and efficiency aspects of information, it is still vulnerable to the fact that the Internet is not secure in terms of security and is not safe to secure of security mechanism. Repeating patches on continuous hacking are continuously demanding additional resources for network or system equipment, and consequently the costs continue to increase. Businesses and individuals alike are speeding up the damage caused by crime like of ransomware, not jusy simple attacks, and businesses and individuals need to respond to cyber security. In addition, the ongoing introduce of security device, and separate of networks for secure transmission of contents in the existing TCP/IP system, but it is still lacking in security. To complement the security implications of this existing TCP/IP Internet Protocol, we intend to propose a Secure Contents Transport System (SCTS) on the network using the CCN concept.

Information security is becoming a more important factor in distribution of digital contents. Generally, illegal facsimile of high-quality multimedia products such as DVDs, MP3s and AACs is possible without damaging quality. Thus, the illegal distribution of duplicated contents on the Web is causing digital content providers great economic loss. Therefore, a study of security and efficient distribution of digital contents is required. The most important issues in the design of a digital content distribution system are user convenience, execution speed and security. In this study, we designed a digital contents distribution system that uses web caching technology and encryption/decryption techniques in hierarchical structures. We propose a digital content distribution system that improves user convenience, security and execution speed. The superior performance of the proposed system has been proven in the tests. The results of experiment show that the developed system has improved the security of DC without decreasing process speed.

The evolution of internet have opened the world of IPTV. With internet protocol, IPTV broadcasts contents stream. The IP protocol doesn't provide secure service due to IP characteristics. So, it is important to provide both connect and secure service. Conditional Access System and/or Digital Right Management are being used to protect IPTV contents. However, there exist restrictions in the view of security. In this paper, we analyse existing security technologies for IPTV and propose a novel method to enforce security efficiently. In the proposed method, OTP is used for encryption/decryption contents and CAS controls key for encryption/decryption and the right of user. With this scheme, it reduces the load of the system and provides more security.

Corporation's computerization developed by diffusion of internet, and dysfunction of Information is increasing greatly with virus, computing network infringement. Therefore, the today, corporation security is more and more emphasized. Security solution by that importance of security rises so is developing together Security solution is developing to ESM system in existing single system and important thing is function of each security solution and optimizing design of policy. Existent security policy taking a serious view security from external invasion but security of interior the importance rise the today. Accordingly, must construct ESM system of new structure for this. This paper proposes and embodied integration security administration system that solidify interior security utilizing IDS. Experiment external IP and ID access and analyzed the result.

As the electronic commercial transaction is being transacted by contents which can get an illegal intrusion from the outside, we sincerely require security for them. We must consider a protection countermeasure about intrusion from protection of the passive form to protection intrusion of the active one. So the security is required against hackers illegality intrusion into the contents. As soon as the intrusion happens about the contents, the tools providing the monitor of contents are required to minimize the damage to the systems. Modified web contents detection system in this paper prevents the loss of resources and manpower required through individually monitoring on the web. Also, this paper offers rapid support of security that it analyzes the weakness of contents security of the web environment and the cause of the problem with the leakage of information. So this system has the pur pose of protecting the weakness of contents security and the leakage of information.

This study explored the security of Industry 4.0 such as security trends and security threats in Industry 4.0, and security system in Industry 4.0. The threat elements in Industry 4.0 are changing from ICT to IoT and to CPS security, so security paradigm and security System should change accordingly. In particular, environmental and administrative security are more important to solve CPS security. The fourth industry-age security should change to customized security for individual systems, suggesting that the security technology that combines hardware and software in product production design should change from the beginning of development. The security system of the fourth industry proposes design and implementation as a CPS security system as a security system that can accommodate various devices and platforms from a security system in a single system such as a network to an individual system.

Recently, payment method is one of the most hot issues for transaction of contents in mobile and internet markets. Many kinds of mobile contents services are rapidly growing with the combination of internet application services. Payment method algorithms are demanded for the stable transaction between producer and consumer. Security protocol algorithms are widely adapted for mobile Platform terminals. In this Paper, we described security mechanism for the current wireless internet services and compared with the performance result. There are security protocols that based on java machine platform or WAP protocols. The system is based on J2ME technology for the java mobile platform. Based on this technology, a security system is proposed for the service of mobile commerce electronic payment. The system is designed for the stability of transaction so that it enables to apply into many kinds of internet payment system.
