Security threats of wireless networks: A survey

Security will play an important role in wireless networks. In the present scenario, 3G and 4G networks have separate security layers but still there is a possibility of certain prominent types of attacks. In this paper, a survey has been done on all the possible attacks that may occur in present and future scenarios. Wireless network attacks are classified on the basis of access control, authentication, availability, confidentiality and integrity as attacks can appear in the form of Access, channel assignment and at the source end. This paper also reflects about the next generation attacks like Man in the Middle Attack, Denial of Service Attack and Eavesdropping. The security methods and tools which helps to find the protection against different types of attacks is also shown in this paper.
