Satellite based communication is networks in which users in a wide area can access without wired-based ground infrastructure. In particular, the need is emerging due to the recent Ukraine-Russia war. Satellite network systems acquire data that is difficult to observe on Earth as well as communication networks and are also used for research and development, which allows additional data to be produced. However, due to the nature of communication networks existing in outer space, certain vulnerabilities are revealed, and attacks based on them can be exposed. In this paper, we analyze vulnerabilities that may arise due to the nature of satellite communication networks and describes current research, countermeasures, and future research directions.

Common Criteria is a scheme that minimize IT products's vulnerabilities in accordance with the evaluation assurance level. SSDLC(Secure Software Development Lifecycle) is a methodology that reduce the weakness that can be used to generate vulnerabilities of software development life cycle. However, Common Criteria does not consider certificated IT products's vulnerabilities after certificated it. So, it can make a problem the safety and reliability of IT products. In addition, the developer and the evaluator have the burden of duplicating evaluations of IT products that introduce into the government business due to satisfy both Common Criteria and SSDLC. Thus, we researched the relationship among the Common Criteria, the static code analysis tools, and the SSDLC. And then, we proposed how to combine SSDLC into Common Criteria.

To enhance the reliability of programs, developers use fuzzing tools in test processes to identify vulnerabilities so that they can be fixed ahead of time. In this case, the developers consider the security-related vulnerabilities to be the most critical ones that should be urgently fixed to avoid possible exploitation by attackers. However, developers without much experience of analysis of vulnerabilities usually rely on tools to pick out the security-related crashes from the normal crashes. In this paper, we suggest a static analysis-based tool to help developers to make their programs more reliable by identifying security-related crashes among them. This paper includes experimental results, and compares them to the results from MSEC !exploitable for the same sets of crashes.

Following the development of Internet of Things (IoT) technology, the scope of application of IoT technology is expanding to industrial safety areas that detect and prevent possible risks in outdoor environments in advance, away from improving the convenience of living in indoor environments. Although this expansion of IoT service provides many advantages, it also causes security problems such as data leakage and modulation, so research on security response strategies is being actively carried out. In this paper, the IoT-based road construction risk management system in outdoor environment is proposed as a research subject. As a result of investigating the security vulnerabilities of the low-power wide-area (LPWA, BLE) communication protocol applied to the research targets, the security vulnerabilities were identified in terms of confidentiality, integrity, and availability, which are the three major elements of information security, and countermeasures for each vulnerability were proposed. This study is meaningful in investigating and analyzing possible vulnerabilities in the operation of the IoT-based risk management system and proposing practical security guidelines for each vulnerability.

Power control system like SCADA(Supervisory Control And Data Acquisition) is gathering information using RS232C and low-speed analog communication network. In general, these methods are known as secure because of the secure characteristics from the analog based communication network and serial communication. In this study, first we build DNP communication environment using commercial power control simulator and find some vulnerabilities by testing from the viewpoint of confidentiality, integrity and availability. Consequently, we see the necessity of a valid method for authentication and data encryption when gathering information, even though that is known as secure so far. Discussion of needs of DNP authentication and data encryption is started about several years ago, but there is still nowhere applied that on real environment because the current methods can not fully meet the security requirements of the real environment. This paper suggests a solution to the vulnerabilities, and propose some considerations for enhancing power control system's security level by applying DNP authentication and data encryption.

CNG which was released as a substitute of the previous CAPI (Cryptography API) library from Microsoft is constructed with individual modules based on the plug-in architecture, this means CNG is exceedingly helpful in the cost of development as well as the facility of extension. On the opposite side of these advantages, considerations on security issues are quite insufficient. Therefore, a research on security assurance is strongly required in the environment of distributing and utilizing the CNG library, hence, we analyze possible security vulnerabilities on the CNG library. Based on analyzed vulnerabilities, proof-of-concept tools are implemented and vulnerabilities are verified using them. Verified results are that contents of mail, account information of mail server, and authentication information of web-sites such as Amazon, E-bay, Google, and Facebook are exposed in Outlook program and Internet Explorer program using CNG library. We consider that the analyzed result in this paper can improve the security for various applications using CNG library.

The purpose of the present study is to empirically examine factors that affect the information security awareness and perceived information security risk of employees of port companies. In particular, in order to identify factors that affect the perceived information security risks, we investigated the relation of assets, threats, and vulnerabilities to it, using the risk analysis methodology. With A total of 252 valid questionnaires, we also performed the structural equation modeling analysis using AMOS. It was found that first, there was no meaningful relationship between the information assets and the perceived information security risk in the case of employees of port companies. Second, threats and vulnerabilities turned out to have positive influences on the perceived information security risk. Finally, there was a positive relationship not only between the information security awareness and the information security education, but also between the information security awareness and the intention of information security. However, there was no meaningful relationship between the information security concern and the information security awareness.

Today, the typical web hacking attacks are cross-site scripting(XSS) attacks, injection vulnerabilities, malicious file execution and insecure direct object reference included. Web hacking security systems, access control solutions, access only to the web service and flow inside but do not control the packet. So you have been illegally modified to pass the packet even if the packet is considered as a unnormal packet. The defense system is to fail to appropriate controls. Therefore, in order to ensure a successful web services diagnostic system development is necessary. Web application diagnostic system is real and urgent need and alternative. The diagnostic system development process mu st be carried out step of established diagnostic systems, diagnostic scoping web system vulnerabilities, web application, analysis, security vulnerability assessment and selecting items. And diagnostic system as required by the web system environment using tools, programming languages, interfaces, parameters must be set.
