Voice over Internet Protocol (VoIP) is an emerging trend of applications on the internet today. As with any recent technology, VoIP also introduces both fortuity and problems. Existing VoIP honeypot experimental set ups based on SIP (Session Initiation Protocol) deals with the basic attacks like DoS (Denial of Service), enumeration detection, signature collection and SPIT (Spam over Internet Telephony). These VoIP service abuse attacks cause discrepancy between the services offered to the VoIP users and service providers. We executed successive attempts with different sets of attributes and sample subsets to collect exact traffic records used for detecting and categorizing the attack packets using honeypot. Finally, a comparison of both the algorithms with its true and false positive rates is evaluated. For result analysis, we propose a test-bed using Zoiper (SIP clients), Asterisk server, Artemisa honeypot and Wireshark as network analyzer. The test-bed demonstrates how the honeypot effectively works in improvising the robustness of the VoIP security system from billing attacks and toll frauds.
In modern industrial field, the requirement for monitoring and controlling system is one of the most important criteria for minimizing the power consumption. In this paper, an effort is made to monitor and control the speed of the motor through TCP/IP connection using virtual instrumentation, LabVIEW. A design of PIC microcontroller along with Ethernet module is presented. Parameters such as Temperature, voltage, current can be monitored and read out with the help of internal ADC. A web server can be embedded into any appliance and connected to the Internet so the appliance can be monitored and controlled from remote places through the browser in a desktop. By typing the IP address on the web browser the user get a web page on the screen; this page contains all the information about the status of the devices. By providing password, we can log on to the system and proceed the monitoring and controlling process. With the help of LabVIEW software the system provides high accuracy and flexibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
