Abstract	Wireless Sensor Networks (WSNs) have become an essential part of modern intelligent systems such as smart healthcare, home automation, traffic monitoring, and environmental sensing. Since sensor nodes operate with limited battery power, storage, and processing capability, they are highly vulnerable to different security attacks. Although several methods including encryption, secure routing, authentication, and key management have been proposed ,none of them alone can fully safeguard of the network. This paper reviews the major security challenges in WSNs and examines commonly reported attacks such as Sybil and Sinkhole attacks. It also provides an overview of intrusion detection techniques used in recent research and compares their performance in terms of accuracy, energy consumption, and real-time capability. Finally, the study highlights open issues in existing approaches and suggests future research directions for designing lightweight and more efficient security solutions for WSNs
