There
are various types of attacks possible in WSN. Wireless sensor network is
vulnerable to attacks due to its deployment over the environment. Attacks are
classified into two types active and passive. Active attack modifies the data
(information) stored or communicate over the system, but passive attacks
doesn’t do any modification so passive attacks are hard to detect 5.

Different
types of attack possible in wireless sensor network are:

Jamming
Attack: This attack is caused by meddling the radio
frequency of attacker nodes with alternate nodes. This is completed by
transmission of radio signals. It mainly causes refusal of administration and
called as Denial of service attack.

Collision
Attack: In this collision attack, at whatever
point the authentic node is transmitting information, the attacker hears the
transmission and transmits its own flag for creating disturbance. Indeed, even
a collision of single byte can create mistake and harm whole message. This
collision attack is superior to sticking attack as for utilization of energy
and discovery capacity.

Sinkhole
Attack:  In the Sinkhole
attack, the primary goal of the attacker is to draw in all the activity. The
traded off node may tune in for the demand for courses because flooding and it
tries to give a false course advising the nodes about the shortest path.

Sybil
Attack: The attacker is having numerous characters
and having copies and present in different areas. It essentially targets the
blame tolerant system like storage, network topology, multipath routing,
information accumulation, voting, trouble making discovery and reasonable asset
assignment etc.

Wormhole
Attack: This
attack requires the presence of at least two malicious nodes. They build up a
wormhole connection between the two malicious nodes. At that point, the packet
got at one area of the system are directed to the next area of the system.
