2 Outline Security Challenges 1 Security Principles 2 WSN Attacks 33 Conclusion 44 2Security in WSN

3 Security Challenges The broadcast nature of the wireless communication. The network deployment in hostile environments (e.g. battlefield, forest) with relatively poor physical protection. The limitations in energy, computational power and memory. The extremely large number of interacting devices in a sensor network. The dynamic nature of WSN (frequent changes in both its topology and its membership) 3Security in WSN

4 Security Principles Data Confidentiality: Ensuring that only authorized sensor nodes can access the content of the messages. Data Authentication : Ensuring that the data is originated from the correct source. Data Integrity: Ensuring that any received data has not been altered in transmit by unauthorized parties. Data Freshness: Ensuring that no old messages have been replayed. Availability: Ensuring that services offered by whole WSN or by a single sensor node must be available whenever required. 4Security in WSN

5 Type of Attacks From the point of view of how to Attack: Passive : Only monitors the communication channel. Threatens the confidentiality of data. Active: Attempts to delete, add or alter the transmission on the channel. Threatens data integrity, authentication and confidentiality. From the point of view of Attackers Device: Mote-Class Attacker: Has access to a few nodes with similar capabilities to those deployed in the network. Laptop-Class Attacker: Has access to more powerful devices like a laptop. Has advantages over legitimate nodes like greater battery power, more capable cpu and high-power antenna. From the point of view of penetration to Network: Insider: Has compromised some authorized nodes of the network (stolen key material, run malicious code). Outsider: Has no special access to the network. Security in WSN5

6 Attacks in WSN(1/6) Security in WSN6

7 Attacks in WSN(2/6) Physical Layer Jamming: Interference with the radio frequencies a network's nodes are using. 7Security in WSN

8 Attacks in WSN(3/6) Data Link Layer Collision: Altering of transmission octets to disrupt the packets. (checksum mismatch) 8Security in WSN

9 Attacks in WSN(4/6) Network Layer Sinkhole: The adversary attracts the surrounding nodes with unfaithful routing information. 9Security in WSN

10 Attacks in WSN(5/6) Network Layer Wormhole: The adversary tunnels the traffic received in a part of the network to another. 10Security in WSN

11 Attacks in WSN(6/6) Network Layer Sybil attack: A single node presents multiple identities to other nodes. E E C C M M Identity Table: Current = X F F B B D D A A Identity Table: Current = X,A Identity Table: Current = X,A,C Identity Table: Current = X,A,C,B Identity Table: Current = X,A,C,B,D N N 11Security in WSN

12 Conclusion Need for physical network protection (not always possible). Cryptography can provide link layer encryption and authentication mechanisms (MAC) but this is not enough. End to end security mechanisms are impractical. Careful protocol design (routing, localization, data aggregation) with respect to security principles and attacker models. Consideration of energy issues when adapting countermeasures. Security in WSN12
