Wireless Sensor Network (WSN) is the most employed network service in commercial and industrial
applications, for the ease of its technical development in a processor, communication, and low-power usage of embedded
computing devices. Sensor nodes are used for constant sensing, event ID, event detection & local control of actuators. The
applications of WSN mainly include health, military, environmental, smart home technology, & other commercial areas.
When deployed in hostile environmental conditions, the sensor nodes are vulnerable to physical capture and other
constraints that puts security as a major challenge for the researcher’s in the field of computer networking. The inclusion of
wireless communication technology also incurs various types of security threats. The intent of this paper is to investigate
the security related issues and challenges in wireless sensor networks. We identify the security threats, review proposed
security mechanisms for wireless sensor networks. We also discuss the holistic view of security for ensuring layered and
robust security in wireless sensor networks.

Wireless Sensor Network, Security, Denial of Service (DoS), Intrusion Detection System (IDS), Authentication, Sensor,
Attacks, Holistic Approach
Most of the attacks against security in wireless sensor
networks are caused by the insertion of false information
by the compromised nodes within the network. For
defending the inclusion of false reports by compromised
nodes, a means is required for detecting false reports.
However, developing such a detection mechanism and making it efficient represents a great research challenge.
Trust management mechanism, as an important
complement for password-based system, has significant
advantages for the WSN in the settlement of internal
attack, identifying malicious nodes, system security and
reliability improvement, and so on. Again, ensuring
holistic security in wireless sensor network is a major
research issue. Many of today’s proposed security schemes
are based on specific network models. As there is a lack of
combined effort to take a common model to ensure
security for each layer, in future though the security
mechanisms become well-established for each individual
layer, combining all the mechanisms together for making
them work in collaboration with each other will incur a
hard research challenge. Even if holistic security could be
ensured for wireless sensor networks, the costeffectiveness
and energy efficiency to employ such
mechanisms could still pose great research challenge in the
