A Survey on Various Security Threats and Classification of Malware Attacks, Vulnerabilities and Detection Techniques

The rapid growth of Wireless Network has raised a great concern for security threats. Currently, security is regarded as one of the critical parameter for the acceptance of any wireless networking technology. Any node under attack in wireless network presents an anomalous behavior called the malicious behavior. In this circumstance, the entire operation of a network gets troubled and to prevent such malicious behaviors, several security resolutions have been found. Malware is a common term that is used to define the type of malicious software that plays a vital role in security threats to the computer and Internet. In this paper, the categories of malware, malware vulnerabilities and the existing handling mechanisms are discussed. Keywords Security Threats, Malware Attacks, Malware Vulnerabilities, Malicious propagation. 1. Introduction A security threat is a potential cause of unwanted event, which may result in damage to a system or a network. Wireless networks are exposed to various threats and attacks. Out of which malware attacks pose serious threats to the wireless networks exploiting the fundamental limitations of wireless network [1], such as limited energy, dynamism in topology due to mobility and unreliable communication.
