Monitoring and Evaluating Open Wireless LAN using Hybrid IDS

In this ever-growing wireless technology era, the number of Open Wireless Local Area Network (WLAN) are on the rise. From cafes to shopping areas, most of them offer users with a free-to-use WLAN which popularly known as Open Wi-Fi or Wi-Fi Hotspots. Although it is a convenient for them to access the Internet at these places, later they know it also makes them a vulnerable target for attackers that might be lurking in the same network they are connected. Therefore, a Hybrid IDS that combines both SNORT, a network-based IDS (NIDS) and OSSEC, a host-based IDS (HIDS) was developed to curb the problem. NIDS was used to monitor network traffics while HIDS monitor user’s system for any suspicious activities. Then, a system that can control and manage both IDS in the much easier and simpler way was developed using Python programming language. The system then can generate alerts with the help of both IDS to notify users for any suspicious activities that might occur in the network or user’s system. Several attacks were launched from the attacker’s laptop to test whether Hybrid IDS can generate alerts to notify the victim. As a result, the system breeze through the testing phase by showing necessary output. All the results were taken and then compared with other scenarios to determine whether they can give the same results as Hybrid IDS. From the comparison results, it can be said that Hybrid IDS can give the extra protection layer towards Open Wi-Fi users. Therefore, the Hybrid IDS was proven to provide vast tracking detection for suspicious activity in the network environments by monitor and alert the users about malicious activities. 

NetFPGA: status, uses, developments, challenges, and evaluation

The constant growth of the Internet, driven by the demand for timely access to data center networks; has meant that the technological platforms necessary to achieve this purpose are outside the current budgets. In this order to make and validate relevant, timely and relevant contributions; it is necessary that a wider community, access to evaluation, experimentation and demonstration environments with specifications that can be compared with existing networking solutions. This article introduces the NetFPGA, which is a platform to develop network hardware for reconfigurable and rapid prototyping. It’s introduces the application areas in high-performance networks, advantages for traffic analysis, packet flow, hardware acceleration, power consumption and parallel processing in real time. Likewise, it presents the advantages of the platform for research, education, innovation, and future trends of this platform. Finally, we present a performance evaluation of the tool called OSNT (Open-Source Network Tester) and shows that OSNT has 95% accuracy of timestamp with resolution of 10ns for the generation of TCP traffic, and 90% efficiency capturing packets at 10Gbps of full line-rate
