Özet:

With the rapid increase in the use of wireless networks today, wireless devices in almost every area of everyday life have become an unchanged part of our lives. With rapid technological developments, security-based solutions are constantly renewed and new solutions are produced. Many protocols are used for the transmission of data and packages for network security in existing systems. The most important of these are IPSec Internet Protocol Security, WEP Wireless Equivalent Privacy, WPA Wireless Proteced Access, RSN Robust Security Network, ESP Encapsulated Security Payload, AHP Authentication Header protocols. Some of these protocols are security protocols that increase the level of encryption, some authorization, and some both encryption and authorization. In addition to these, the security wall is used in different methods, such as IKE Internet Key Exchange, to increase the security level. In addition, the VPN Virtual Private Network provides connectivity to networks via the Internet via the IP tunnel. All these methods still do not provide full security in wireless networks. This study examined the systems developed for various wireless networks and called them multi-layer and revealed how the implementation of multiple protocols, security walls and VPNs, which are the three key elements of security at the same time, increased the security in wireless networks and how the performance of average data traffic received in data transmission, along with these three factors, was affected.
