METHODS OF DETERMINATION OF INTERFERENCES IN WIRELESS COMPUTER NETWORKS

Abstract

The subject of the latest research is wireless security, which remains a major issue in LANs around the world. While wireless networks offer convenience and flexibility, they also increase network vulnerability. Security threats such as unauthorized access, denial of service attacks, IP and MAC address spoofing, session theft, and eavesdropping can be problems for WLANs. To counter these threats, various standard authentication and encryption methods are combined with other access control mechanisms. These protocols, devices and methods combine to provide a WLAN level of security equal to or even greater than that of a wired LAN. The methods and technologies used in WLAN security in relation to this study include: Wired Equivalent Privacy (WEP). An older encryption standard used to eliminate security threats. WEP secures the WLAN by encrypting transmitted information so that only receivers with the correct encryption key can decrypt the information; WPA / WPA2 (Secure WI-FI Access). Improvement of WEP by introducing the Temporal Key Integrity Protocol (TKIP). Even when using RC4 encryption, TKIP uses a temporary encryption key that is regularly updated, making it difficult to steal. In addition, data integrity has been improved by using a more robust hashing mechanism; Wireless Intrusion Prevention Systems / Intrusion Detection Systems. Intrusion Detection and Prevention focuses on the radio frequency layers. This includes radio scanning to detect rogue access points or ad hoc networks for network access control. Advanced implementations are able to visually represent the network area along with potential threats and have automatic classification capabilities so that threats can be easily identified. The purpose of the study is to identify existing wireless sensor networks (WSNs) penetration methods by analyzing their methods of communication with each other, hardware and software for reliability and resistance to possible threats.
