ARP poisoning attack
Source publication
In today's world maintaining the security of information is a must. LAN is generally most common & very useful network in every organization. ARP is a mapping protocols from IP to MAC.ARP has two limitations. First it is a stateless protocol. And second no authentication process required for any host of the LAN. Attacker can easily exploit these vu...

An increasing reliance on cloud and distributed processing of scientific and big data in commercial, academic, and government institutions necessitate new approaches to optimize file transfers. Lossless data compression and decompression is essential in improving the overall effectiveness of file transfers between edge devices and the cloud by incr...
We analyze the statistical properties of the local
area network (LAN) traffic data collected from a part of the
campus of St. Petersburg Electrotechnical University. The entire
LAN is subdivided into several subnets, thus we focus on the
analysis of the downlink traffic fluctuations at several levels,
including individual end users’ devices (end-IP...
Commonly abbreviated Local Area Network LAN is a computer network that covers only a small area networks, such as campus computer networks, buildings, offices, in homes, schools or smaller. Currently, most LANs based on the IEEE 802.3 Ethernet technology using devices such as hubs and switches devices, which have a data transfer speed of 10, 100, o...

Contemporary data processing activities often producing, manipulating, or consuming large amount of data. These activities require a method of data compression to reduce bandwidth usage and speed up the process of sending data through a network. Compression method that used in compresed that researched in this paper is algorithms Rice Coding and co...

Nowadays security is a major concern. Address resolution Protocol (ARP) is a most popular communication protocol in the LAN. ARP is mapping from IP address (32 bits) into MAC address (48 bits). ARP has some limitations like lack of states and authentication. S o attacker can exploit these vulnerabilities and gain unauthorized access to one's sensitive data. There are some attacks against ARP like MAC S poofing, MAC duplicating, Man-in-the-middle (MITM) and denial of services (DOS). S o efficient and secure scheme is provided which prevents ARP attacks. This paper demonstrates a utility which gives users the authentication as well as detection and prevention of ARP poisoning in dynamic IP configuration. Utility provides a mechanism which is based on internet control management protocol (ICMP) which uses secondary cache for checking pair entry of IP-MAC respective the system in the network.
