Introduction

• Vehicular ad-hoc network is a special kind of
  network in which nodes (Vehicles) can communicate
  with each other on the road and with its
  Infrastructure.

VANET Security Requirements

• Vehicular network applications require security
  and the objective of these applications is to
  serve users and make their journey secure and
  comfortable.
• Attackers have their own role in this network and
  we cannot predict the dynamic behavior of the
  attacker. If an attacker works on a safety
  application and changes the content of the safety
  message then it poses a very difficult condition
  on the road and many users will be affected due
  to this kind of attack.
• Accidents are often the result of an alteration
  of any safety message or the sending of even one
  wrong safety message in a network and many human
  lives are at risk 1.

Attacks on Availability in VANET

• DENIAL OF SERVICE (DOS)
• In VANET, DOS shall not be allowed to happen,
  where seamless life critical information must
  reach its intended destination securely and
  timely. In summary, there are three ways the
  attackers may achieve DOS attacks.
• There are three levels of DOS attacks as
  described below.
• Basic Level Overwhelm the Node Resources
• Extended Level Jamming the Channel

Security goals (CIA) with threat levels in VANET

Conclusion

• Based on the literature survey, it is understood
  that attackers launch different types of attacks
  while communication is in progress in the
  network. These attacks break the security goals
  like confidentiality, integrity and availability
  (CIA) in the VANET environment.
• These goals have equal importance to serve the
  users but the availability leads to high
  priority. It is observed that the attacks related
  to the availability have more threat level as
  compare to the integrity and confidently.
