The purpose of this study is to analyse motor vehicle communication network hacking attacks and to provide its prevention. First, the definition of motor vehicle communication network was provided and types of in-vehicle communication network were discussed. Also, bluetooth hacking attack cases were analysed in order to illustrate dangers of hacking attacks. Based on the analysis, two preventive measures were provided. First, Motor Vehicle Safety Standard Law should be revised. Although the law provides the definition of electronic control system and its standards as well as manufacturing and maintenance for safe driving standards, the law does not have standards for electronic control system hacking prevention and defensive security programs or firmware. Second, to protect motor vehicle communication network, it is necessary to create new laws for motor vehicle communication network protection.

This study is a file management security system that encrypts and decrypts computer and cloud data by using Bluetooth based cryptographic module. It is a necessary solution in terms of abuse of personal information and protection of social and national information. We developed H/W and S/W for SFMS(: Safe File Management Security) related Bluetooth module in cloud environment and implemented firmware development, encryption key generation and issuance, client program for system mobile and key management system. In the terminal internal encryption and decryption, SFMS was developed to ensure high security that the hacking itself is not possible because key values exist separately for each file.

To defend against information leakage or malware inflow by USB memory, security technologies such as copy protection and device control have being researched and developed. However, countermeasure are insufficient despite being recognized as a fatal security-hole for BadUSB presented at the Black Hat Security Conference 2014. To solve this problem, the countermeasures for BadUSB vulnerability are proposed.

There are many modern societies use the digital products in everyday life in the Middle, convenience, give him plenty of Bluetooth is one of the users. Bluetooth (IEEE 802.15.1) means equipment in the close range between the low-power wireless communication standard for the connection to use the technology. Currently, Bluetooth earphone, Bluetooth speaker, wearable mounted devices also used a lot because it takes people to exploit the benefits had been lifted and thereby increases your damage. So, reducing the damage the user's further research about the security technique that can stop completely. I am sure that many Bluetooth hacking techniques, a Bluetooth device firmware vulnerability within the stored data to allow the approach to attacking the BlueTooth Snarfing and want to analyze.

After the corona virus, as non-face-to-face services are activated, domain services that guarantee integrity by embedding sensing information of the Internet of Things (IoT) with block chain technology are expanding. For example, in areas such as safety and security using CCTV, a process is required to safely update firmware in real time and to confirm that there is no malicious intrusion. In the existing safe security processing procedures, in many cases, the person in charge performing official duties carried a USB device and directly updated the firmware. However, when private blockchain technology such as Hyperledger is used, the convenience and work efficiency of the Internet of Things environment can be expected to increase. This article describes scenarios in how to prevent vulnerabilities in the operating environment of various customers such as firmware updates and device changes in a non-face-to-face environment. In particular, we introduced the optimal blockchain technique for the Internet of Things (IoT), which is easily exposed to malicious security risks such as hacking and information leakage. In this article, we tried to present the necessity and implications of security management that guarantees integrity through operation applying block chain technology in the increasingly expanding Internet of Things environment. If this is used, it is expected to gain insight into how to apply the blockchain technique to guidelines for strengthening the security of the IoT environment in the future.
