Wireless networks spread in areas of without physical access to reach the available smart phone or laptop network, as well as meet the needs of convenience. Although wireless networks send and receive data wirelessly, they can be intercepted when compared to a vulnerable wired network security. In this paper, the signature-based detection with Snort Wireless and iptables uses Wireless attack detection and prevention measures to implement a wireless intrusion prevention system. Additionally, to validate the performance of a wireless intrusion prevention system a mock hacking can be conducted. Keywords: iptables, Kali Linux, Snort, Snort Wireless 1. Introduction Portable Equipment Use Increase Due to Wireless Network Usage Increasing A wireless Network Cable Network Physical Connection Without Internet Use Possible That Convenience and Cable Network and Analogous Quality Provides but Wireless Network Propagation Using the Data, Send and receive Because of Such Features of the Security Vulnerability to Implies A. Security Vulnerability to Complement For Certification and Encryption Techniques [1] But Attack Of technologies Development of Due to Security Technology Limit Had reached [2]. Wireless Invasion Prevention System [3] Outside Invasions Detection and by blocking Inside System Protect and Wireless Use Specific Environment Based on Operation [4]. Commercial Wireless Invasion Prevention System Wireless Network Required Cost Reduction was not suitable. This Paper Open Sources Using the Built and simulated Hack Conducted by Invasion Prevention System Requirements Meets Verified. 2.
