Metamaterials are currently being extensively studied not only for their future potential applications in novel electromagnetic devices but also for the fundamental electromagnetic phenomena that cannot be observed in conventional media. Waveguides of metamaterial inclusions have been ones of significant research areas in metamaterials due to their potentials in near field optics and integrated circuit...
There are a lot of studies that have measured TCP traffic, but none of them provide the investigation results of TCP SYN packet. In this paper, we show and explain common behavior of TCP SYN packets in traces from a research center using various statistical analysis methods. We selected three parameters to find the behavior of TCP SYN traffic - number of received SYN packets in every 10 ms, SYN PPS...
Nowadays BcN is researched and developed for supporting the service e-commerce, telecommunication and ubiquitous computing. Internet gives us the benefit of remote access to the information but causes the attacks that can break the server and modify the information. Since 2000 Nimda, code red virus and DDoS attacks are actuated in Internet. This attack programs makes tremendously traffic packet on...
Signature-based IDS is known to have acceptable accuracy but suffers from high rates of false alarms. We show a behavior based alarm reduction by using a memory-based machine learning technique - instance based learner. Our extended form of IBL (XIBL) examines SNORT alarm signals if that signal is worthy sending signals to security manager. A preliminary experiment shows that these exists an apparent...
