The Wireless sensor network (WSN) is one of the most emerging and developing technologies that promises a variety of security features. Providing security to the sensor network is the prominent characteristic to avoid network based attacks. The Sybil attack is the most frequently occurring attacks against the sensor networks, where one malicious node can gain access using different identities illegitimately. Here, we illustrate the threats presented by the Sybil attack and the defenses against such attacks to enhance the security for many network applications. This attack can be exactly determined with the help of certain functions such as position verification, routing, transitory master key. Various types of sybil attack have been organized and explained to have better knowledge about the differences between each type and the procedure to counteract against such threats. Thus, the approach has been presented to avoid such attacks to provide the effective sensor network .
