Drone remote identification (ID) capability is essential to ensure public safety, help law enforcement, and secure the safety and efficiency of the national airspace. Remote ID technology can be used to differentiate compliant drones from illegal drones that pose a potential security risk by providing airspace awareness to the civil aviation agency and law enforcement entities. In addition, the increased safety and efficiency obtained by mandating remote ID will make it possible to operate drones over populated areas and beyond visual lines of sight. In addition, remote ID will allow drones to be safely integrated into unmanned traffic management systems and the national airspace. Remote ID devices can be categorized by type, i.e., broadcast remote ID or network remote ID. The broadcast remote ID, which has high technical maturity and will be applied in the near future, is primarily considered to ensure the security of drones. The network remote ID, which is being developed and tested and will be applied in the distant future, can be used additionally to ensure the safety and the efficiency of the national airspace. In this paper, we analyze the trends on regulation and standardization activities for drone remote ID primarily in the United State and Europe.

In 2012, Sonwanshi et al. suggested an efficient smar card based remote user authentication scheme using hash function. In this paper, we point out that their scheme is vulnerable to offline password guessing attack, sever impersonation attack, insider attack, and replay attack and it has weakness for session key vulnerability and privacy problem. Furthermore, we propose an improved scheme which resolves security flaws and show that the scheme is more secure and efficient than others.

Management for security product and application is becoming more difficult because they became more specialized. Most of research is focused on combining policies for information security management policy, security standard, and security tools. However, there are no researches for total solution for both application and security policy. Thereby, the purpose of this research is to propose a remote integrated management system based on linux. The system could efficiently manage data update for application and policy update for a server supporting the distinct configuration of each server. By using the remote integrated management system, system manager with poor secure knowledge also could easily manage their system securely.

The pandemic caused by the COVID-19 virus, which has lasted for the past three years, has changed society and the way people live in many ways. These changes also affect cyberspace, so the pre-pandemic information security model and standards have limitations when applied to the current situation. In this paper, a new method to improve the information security model of public institutions was proposed in consideration of various situations in the new normal era. In other words, through the proposed information security model, the possibility of external intrusion is blocked in advance through the policy and technical supplementation of remote work, which is a weakness of the existing information security operation of public institutions. Also, how to prevent abnormal authentication attempts by building a secure VPN environment, how to prevent social engineering cyber attacks targeting fear and uncertainty caused by COVID-19, and how to use a smooth network and create a remote work environment. For this purpose, methods for securing service availability were additionally presented.

In the current cloud environments, the applications are executed on the remote cloud server, and they also utilize computing resources of the remote cloud server such as physical memory and CPU. Therefore, if remote server is exposed to security threat, every applications in remote server can be victim by several security-attacks. Especially, despite many advantages, both individuals and businesses often have trouble to start the cloud services according to the malicious administrator of the cloud server. We propose a security-enhanced local process executing scheme resolving vulnerability of current cloud computing environments. Since secret data is stored in the local, we can protect secret data from security threats of the cloud server. By utilizing computing resource of local computer instead of remote server, high-secure processes can be set free from vulnerability of remote server.

This paper presents new type remote home automation that can control and manage hi-directionally and efficiently home appliances and home security systems in home through Internet. The system is used virtual reality technology to construct very easy user interface and used Internet as network for remote control. Here, the user interface is 3D GUI which gives user feeling to be at his home on web-browser, and also shows him present state of control objects at home. This system has been implemented on the basis of Java and VRML. In this paper we propose the internet-based remote control system, and show usefulness of the suggested system by applying to home automation system.

Currently, most companies have security solutions such as firewalls or WAF (Web Application Firewall) for web services, cloud systems, and data centers. Recently, as the need for remote access increases, the task of overcoming the security vulnerabilities of remote access control is becoming more important. In this paper, the concept of the network security model from the perspective of zero trust and the strategy and security system using it will be reviewed.

Drone refers to an unmanned flying system according to the remote control. That is a remote control systems on the ground or a system that automatically or semi auto-piloted system without pilot on board. Drones have been used and developed before for military purposes. However there are currently utilized in a variety of areas such as logistics and distribution of relief supplies disaster areas, wireless Internet connection, TV, video shooting and disaster observation, tracking criminals etc. Especially it can be actively used in activities such as search or the structure of the disaster site, and may be able to detect the movement of people and an attacker using an infrared camera at night. Drones are very effective for private security.

A VPN(Virtual Private Network) is constructed using public wires to connect nodes. It can be used like the dedicated line and maintain the security of the data on the VPN. And It uses encryption and other security mechanisms to ensure that only authorized users can access the network. In this paper we summarize IPsec and VPN technology and construct pilot VPN system for analyzing the performance of remote access VPN. Then we analyze the performance of remote VPN system using VPN concentrator in case of single user and in case of multi users.
