Security Attacks in Wireless Communication

Question: Describe about the Security Attacks in Wireless Communication? Answer: The Security attacks targeting the WLANs Wireless Local Area Network brings a new way of complete mobility where the source of communication is not bounded within the infrastructure of wires[1]. Various security attacks are present in the wireless infrastructure. Some attacks are present which are not particularly dangerous. The state-of-the-art security attacks that target the WLANs are: Channel congestion: The security attackers are responsible for jamming the wireless channel present in the physical layer. They effectively reject the network access to valid users. Unauthorized right to use: The time when authentication is not available, the attackers get the opportunity to use free network. They even use the Access Point for accessing the internal network and bypassing the firewall[2]. Analysis of Traffic: The security attackers have the capacity to examine the recorded wireless traffic for obtaining information related to network usage patterns. Session hijack: A security attackers require only two steps to hijack an existing session. At first, the hijacker breaks the course with the help of wireless conflict. Then the hijacker covers the official station and recaps the earlier validation messages. Countermeasures for overcoming the security attacks The proposed countermeasures that can protect WLANs from any security attacks are as follows: At first, the WLAN connection provider needs to create a WLAN security policy to secure their networks. They need to modify the default Service Set Identifier[3]. The WLAN network provider needs to implement strong encryption rules for protecting the system. The implementation of integrated wireless intrusion protection can protect the WLAN network connections without interrupting the services[4]. References Vani, B., 2014.
