Effects of Attackers and Attacks on Availability
Requirement in Vehicular Network A Survey

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.

AVAILABILITY REQUIREMENT IN VANET

• Availability is one of the hot research topics in
  vehicular communication. The purpose of a
  vehicular network is to serve the users. But if
  the network is not available for communication
  then the main goal of the network has become
• useless.
• If an accident happens in location X and the user
  sends this information to another vehicle but the
  channel is not available due to a DoS attack,
  this makes availability of network a significant
  factor.

ATTACKERS AND ATTACKS ON AVAILABILITY IN VANET
10
A.DENIAL OF SERVICE (DOS) ATTACK IN VANET

• 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

11
A. DENIAL OF SERVICE (DOS) ATTACK IN VANET

• Drop Communication Packets
• It is also called network DoS attack, selfish
  node or malicious node drop communication packets
  in network. This is also one of the aspects
  related to behavior of an attacker in which an
  attacker just drops the packets the purpose of
  this is to ensure that users do not perform any
  type of communication in the network.

12
B. Distributed Denial of Service (DDoS) Attack
13
C- Broadcast Tampering Attack

• In this case, an attacker tampers with the
  broadcast safety message and possibly injects
  false safety message. The purpose of this is to
  cause road accidents or change the flow of
  traffic on some specific route.

14
D- Malware Attack

• A vehicle has its own software and application
  unit (AU) which performs its own task and
  communicates with other users as well as the road
  side unit (RSU).
• There is some possibility to enter a virus and
  worm into the vehicle and disturb the operation
  of the network.

15
E- Spamming Attack

• In this situation, the sole purpose of the
  attacker is to increase the latency of the
  transmission and use up the bandwidth of the
  network so no service is available to other
• users this is achieved by sending spam messages
  through the network.
• It is nearly impossible to control attacks of
  this type when there is no basic infrastructure
  or centralized administration available.

16
F- Black Hole Attack

• Blackhole is a different kind of attack and there
  are two possible cases in any particular
  vehicular network.
• When any new user wants to start communication
  with other users or simply participate in a
  network, then other users simply refuse it. In
  Fig. 11, user D wants to start communication with
  user X, but user X refuses it and simply sends a
  reply with SORRY. So now user D tries To
  communicate with any other user of that network.
• One user starts communication with other users of
  the network and it is suddenly dropped out of the
  communication.

ATTACKS ON AVAILABILITY WITH THREAT LEVELS
18
Conclusion

• In vehicular network, the attackers can launch
  different kind of attacks in network and purposes
  of these attacks are creating problems for
  authentic users of network and also break the
  security requirements.
• So, availability is one of the key security
  requirements in network and due to negative
  behaviour of attackers and attackers this
  security requirements is also effected.
• In this paper, we have provided the detail
  description about the availability security
  requirements and also mentioned the different
  types of attackers who launch attacks related to
  availability of network.
