Using a cybersecurity company's network of web servers as a case study, we propose a technique for analyzing user activity in NGINX logs. The proposed method does not require a labeled dataset and is capable of efficiently identifying different user anomalies in large datasets with millions of daily requests. The results of the analysis provided a deeper understanding of user behavior when seeking updates through web requests and aided in interpreting the findings. Clustering the anomalies helped to produce typical clusters and further supported the interpretation of the results. This work provides valuable insights into user behavior in web server networks and highlights the importance of efficient anomaly detection techniques in large datasets. The findings have potential real-world applications in the field of cybersecurity, particularly in providing network security analysts with an automated and more objective approach to threat analysis. This study showcases the importance of automated methods for analyzing user activity in web server networks and provides a more objective and efficient approach to detecting user anomalies in large datasets. This approach contributes to the development of more effective and precise cybersecurity systems, ultimately improving the protection of network infrastructures from malicious attacks.","PeriodicalId":311611,"journal":{"name":"2023 17th International Conference on Telecommunications (ConTEL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123296271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers seek different approaches to address this issue by proposing algorithms to control or avoid congestion. One of the primary approaches to handling efficient congestion is specifying the amount of data to be transmitted during a period, referred to as the congestion window (cwnd). This paper aims to optimize the congestion window modification by assessing and utilizing the Self-Clocked Rate Adaptation for Multimedia (SCReAM) algorithm's parameters. Our results indicate that we increased the average congestion window by 164.6% in the classic mode and 67.64% in the L4S/ECN mode.","PeriodicalId":311611,"journal":{"name":"2023 17th International Conference on Telecommunications (ConTEL)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123997695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secure Data Aggregation in Cultural Heritage Monitoring: NMEC Case Study 文化遗产监测中的安全数据聚合:NMEC案例研究

To ensure the long-term safeguarding of valuable and significant artifacts housed in museums, regular inspections are necessary. In this specific research study, the National Museum of Egyptian Civilization (NMEC) serves as a case study. To effectively monitor the museum's environment and protect its cultural assets, a wireless sensor network (WSN) is proposed. This network comprises various sensors that monitor crucial environmental factors such as temperature, humidity, and light levels. These sensors collect data, which is then aggregated using a cluster-tree-based architecture. During the aggregation process, the trust score of each node is taken into consideration when selecting cluster heads. This trust score serves as a measure of reliability and ensures that the most trustworthy nodes are responsible for data aggregation and transmission. Ultimately, the collected data is transmitted from the cluster heads (CHs) to the sink base station (BS) located outside the cultural site. To determine the optimal route for data transmission, a routing strategy is employed, considering both the path trust score and energy consumption. The path with the highest trust score and the lowest energy consumption is selected for data transmission, ensuring efficient and reliable communication within the network. The research findings indicate that the system's throughput remains stable throughout 50 sensing iterations. However, after 500 iterations, the throughput experiences a gradual decay to approximately 75% of its initial value. Additionally, the energy consumption of the network remains low, with a measurement of less than 0.2J after 500 iterations.","PeriodicalId":311611,"journal":{"name":"2023 17th International Conference on Telecommunications (ConTEL)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114674890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently published datasets that have the same flow features but different network environments and attacks have eased the research on generalisability and improved method comparison abilities. This paper aims to continue the strive towards generalisability by examining the performance of, primarily autoencoder, and PCA, in an inter-dataset network intrusion detection tasks as these methods have not yet been evaluated across different network environments. The results indicate that while the performance of the traditionally used methods does not fully transfer on different network environments, they do perform better than a random classifier.","PeriodicalId":311611,"journal":{"name":"2023 17th International Conference on Telecommunications (ConTEL)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124622444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since typical IoT devices are resource-constraint, it is challenging to use and deploy secure IoT protocols on such devices: It is thus critical to study the overhead of such protocols for resource-constrained devices, as it significantly affects the performance of an overall IoT solution. In this paper, we analyze the secure variants of the widely used messaging protocol MQ Telemetry Transport (MQTT), namely MQTT with TLS and MQTT with AES. We report the results of our performance evaluation in the context of an IoT solution for Precision Agriculture using an STM32 microcontroller with an NB-IoT module to compare these variants with plain MQTT and determine the most appropriate options based on the amount of data transmitted and achieved security level.","PeriodicalId":311611,"journal":{"name":"2023 17th International Conference on Telecommunications (ConTEL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122904139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
