Address Resolution Protocol (ARP) cache poisoning is a MAC layer attack that can only be carried out when an attacker is connected to the same local network as the target machines. ARP is not a new problem, but wireless network introduces a new attack point and more vulnerable to the attack. The attack on wireless network cannot be detected by current detection tool installed on wired network. In order to detect the ARP poisoning attack, there must be a ARP poisoning detection tool for wireless LAN environment. This paper proposes linux-based ARP poisoning detection system equipped with wireless LAN card and Host AP device driver

In this paper, we developed the tools enabling to manage the IoT systems owned by managers. Since equipment agents consists based on open-source block-chain framework, we can secure the invariance on data and furthermore can locate the resources by searching the AP connected to the equipments. Also the manager can trace the connecting details on equipments from their block-chain accounts. In addition, we work on the possibility of protecting ARP poisoning attacks by removing the credibility on additional ARP requests being generated during the process of network creation.

This paper proposes mechanism to build a economical access control system when a user's host requires block to an external network, such as computer class conducted at educational institutions. The proposed mechanism is to block clients from accessing the external network by using the one of MITM(Man In The Middle) technique, ARP Spoofing. It prevents packets from being forwarded to outside by gateway. So It can build system simply and economically because Client hosts are don't need to install firewall or any extra agent.

본 논문은 MITM 공격기법을 역이용한 네트워크 보안 기술 및 구현 방안을 제시한다. MITM(Man In The Middle) 공격은 통신 경로 중간에 개입하여 양 단간의 통신 내용을 가로채거나 행위 제어를 수행하는 전통적인 해킹 방법으로 그 공격 기법을 역이용하여 네트워크 공격을 방어하는 보안기술 및 시스템 구현에 대해 기술한다. Linux 시스템을 이용하여 ARP Poisoning을 통해 양단간 통신 트래픽에 개입하며, Netfilter 및 Suricata를 이용하여 Network IDS/IPS 및 Firewall을 구현하였고, Contents 필터링 및 Anti-Virus 구현이 가능하며, 여러 기능을 확장하여 UTM(Unified Threats Management) 시스템을 구현하였다.

Is need Remote Access through internet for business of Ubiquitous Computing age, and apply OTP for confidentiality about inputed ID and Password, network security of integrity. Current OTP must be possessing hardware or Token, and there is limitation in security. Install a Snooping tool to OTP network in this treatise, and because using Cain, enforce ARP Cache Poisoning attack and confirm limitation by Snooping about user password. Wish to propose new system that can apply Tokenless OTP by new security way, and secure confidentiality and integrity. Do test for access control inflecting Tokenless OTP at Remote Access from outside. and could worm and do interface control with certification system in hundred. Even if encounter hacking at certification process, thing that connection is impossible without pin number that only user knows confirmed. Because becoming defense about outward flow and misuse and hacking of password when apply this result Tokenless OTP, solidify security, and evaluated by security system that heighten safety.

In this paper, we propose a reversely using the "Man In The Middle Attack" attack technique as a way to introduce network security without changing the physical structure and configuration of the existing network, a Virtual Network Overlay is formed with only a single Ethernet Interface. Implementing In-line mode to protect the network from external attacks, we propose an integrated control method through a micro network security sensor and cloud service. As a result of the experiment, it was possible to implement a logical In-line mode by forming a Virtual Network Overlay with only a single Ethernet Interface, and to implement Network IDS/IPS, Anti-Virus, Network Access Control, Firewall, etc.,. It was possible to perform integrated monitor and control in the service. The proposed system in this paper is helpful for small and medium-sized enterprises that expect high-performance network security at low cost, and can provide a network security environment with safety and reliability in the field of IoT and embedded systems.
