The type of attack in which one malicious node behaves like multiple nodes

The type of attack in which one malicious node behaves like multiple nodes

Sybil attack: Sybil attack is launched by a malicious node which has virtually multiple identities (IDs). We refer to a malicious node's additional identities as Sybil nodes.

What is node tampering attack?

2.2.1.2 Node Capture (Tampering): An adversary. takes over the control of the sensor node by a physical. attack, e.g. attaching cables to its circuit board and reading. stored data as well as ongoing transmission in the WSN [1].

What is the attack in wireless sensor network?

Wormhole attack – The most devastating and complicated attack in a wireless sensor network is the Wormhole attack. In this attack, the attacker keeps track of the packets and makes a tunnel with other nodes of different communication networks, and thus the attacker passes the packets through this tunnel [21].

Which attack can be launched on a WSN?

The attacks on WSN can be largely classified as interception, interruption, modification and fabrication [13]. access of the sensor node and its stored data/keys [11].

What is meant by attack describe the various attacks and threats in WSN?

The WSN attacks can also be classified as passive or active, internal or external, different protocol layer attacks, stealthy or non-stealthy, cryptographic, or non-cryptographic attacks [28] . ... The application layer attacks include clock skewing, selective message forwarding, and data aggregation forwarding [36]. ...

What is sinkhole attack?

Sinkhole attack is a type of attack were compromised node tries to attract network traffic by advertise its fake routing update. One of the impacts of sinkhole attack is that, it can be used to launch other attacks like selective forwarding attack, acknowledge spoofing attack and drops or altered routing information.

What is compromised node?

1. A node on which an attacker has gained control after network deployment. Generally compromise occurs once an attacker has found a node, and then directly connects the node to their computer via a wired connection of some sort.

What is a jamming attack?

A jamming attack is the transmission of radio signals that disrupt communications by decreasing the Signal-to-Inference-plus-Noise ratio (SINR) (Berg, 2008). ... Wireless signal jamming devices are most often used to interfere with wireless networks, a type of denial of service (DoS) attack.

What is Sybil attack in WSN?

The Sybil attack is a massive destructive attack against the sensor network where numerous genuine identities with forged identities are used for getting an illegal entry into a network. ... Basically a Sybil attack means a node which pretends its identity to other nodes.

In which attack high powered wireless signals are used to prevent successful sensor communications?

The main aim of a DoS attack is to direct malicious signals towards the sensor nodes' communication channels to deplete their resources such as the battery life, bandwidth, and storage in order to prevent transmitted sensor data from reaching its destination, thereby affecting its long-term availability [6].

What is active and passive attack in cyber security?

In an active attack, an attacker tries to modify the content of the messages. In a passive attack, an attacker observes the messages and copies them.

What kind of attacks could an adversary initiate by accessing a single sensor node in a large scale WSN?

The unattended nature of wireless sensor networks can be exploited by adversaries which are able to launch an array of different physical attacks including node replication attack, signal or radio jamming, denial of service (DoS) attack, node outage, eavesdropping, and Sybil attack.

What are the application of wireless sensor network?

Applications of WSN:

Surveillance and Monitoring for security, threat detection. Environmental temperature, humidity, and air pressure. Noise Level of the surrounding. Medical applications like patient monitoring.

What is wormhole attack?

Wormhole attack is a severe and popular attack in VANETs and other ad-hoc networks. This attack involves two or more than two malicious nodes and the data packet from one end of the malicious node is tunneled to the other spiteful/malicious node at the other point, and these data packets are broadcasted.

What is sinkhole in Palo Alto?

The DNS sinkhole enables the Palo Alto Networks device to forge a response to a DNS query for a known malicious domain/URL and causes the malicious domain name to resolve to a definable IP address (fake IP) that is given to the client.

What is an Anubis sinkhole?

A sinkhole is where a defender has successfully taken contol of the the malicious domain name, and redirected it to a benign server that gathers information about the infected system. The Anubis Networks Sinkhole is one such server.
