VANETs privacy and security have attracted a lot of attention over the last couple of years. VANETs are being used to boost road safety and empower a wide variety of services like internet, Emergency Message etc. The Vehicular Ad-hoc Network is a collection of smart devices with their vehicle interface. It can play a significant role in the routing process and provide better Security. An increased number of vehicles can raise a number of accidents. That can be part of life loss. So it is the need for smart vehicles that can establish interpersonal communication and warn each other for safety and security. On the other hand, many forms of attacks against VANETs have emerged recently that attempt to compromise the security of VANET networks. Such security attacks on VANETs might cause harmful results. Therefore, making VANETs security has become a key objective for VANET designers. To modify and deploy secure VANET infrastructures remains a significant challenge. The authors portray the different routing protocol by using Octopus diagram, number of attacks and its solution in VANET. With the help of safety and road traffic info among vehicles and related network attacks which improve security under possible attacks in VANETs.
