Recently, with the rapid growth of the Internet of Things(IoT) field and increasing market demand, the use of IoT devices is increasing in daily life and overall industrial areas. However, many IoT devices have been introduced to the market without sufficient consideration of security. With the emergence of attack techniques and various malicious codes, the security aspect is becoming increasingly important. In the IoT environment, the MQTT protocol, which supports efficient communication with small resources, is widely used, and security threats to the MQTT-based IoT environment are expected to increase. In this study, we proposed a sliding window based LSTM deep learning model to detect and classify malicious traffic for the MQTT protocol in the IoT environment. Using the proposed model based on the previously published MQTT traffic dataset and the dataset collected in this study, it was shown that the accuracy was improved compared to previous studies. In addition, we showed that the malicious MQTT traffic is detected in the real time environment.

This study was conducted to get the significant implications for the accreditation of engineering education in Korea from the case of Japan. We researched the terminology of ‘accreditation’, the outline, the current progress, and argument over the accreditation of engineering education in Japan. We suggested the seven implications for ABEEK. First, ABEEK has to use the engineering societies more in assessing the programs. Second, ABEEK should be flexible to meet the original goals. Third, ABEEK can use the observer system to train the examiners. Fourth, ABEEK needs to provide the real benefits to the students and accredited programs to encourage them to finish the accredited course. Fifth, the programs need to organize the committes in the direction that every faculty member can share the assessment results and execute the real course improvement. Sixth, ABEEK should permit the programs to use the curricular courses to check the achievement of program outcomes. And seventh, ABEEK needs to have meta-evaluation to exercise the reasonable authority.
