摘要： This Rapids book unveils a blueprint for safeguarding the very backbone of modern communication networks. It offers a roadmap towards fortifying SDN infrastructures against the relentless onslaught of cyber threats, ensuring resilience and reliability in an ever-evolving digital landscape. This is an exhaustive study of crafting a robust security solution tailored for the SDN environment, specifically targeting the detection and mitigation of distributed denial of service (DDoS) attacks on the control plane. The methodology hinges on an early detection strategy, meticulously aligned with industry standards, serving as a beacon for professionals navigating the intricate realm of implementing security solutions. This reference elucidates an innovative approach devised to identify and mitigate the inherent risks associated with the OpenFlow protocol and its POX controller. Validated through rigorous simulations conducted within controlled environments utilizing the Mininet tool and SDN controller, the methodology unfolds, showcasing the intricate dance between theory and practice. Through meticulous observation of detection algorithm results in simulated environments, followed by real-world implementation within network testbeds, the proposed solution emerges triumphant. Leveraging network entropy calculation, coupled with swift port blocking mechanisms, the methodology stands as a formidable barrier against a DDoS attack such as TCP, UDP, and ICMP floods.

摘要： This study explored factors impacting the decision for gifted females to pursue a career in computer science. The study used a phenomenological approach to delve into the experiences of ten gifted alumnae of The Gatton Academy of Mathematics and Science (Gatton), a residential STEM program, aiming to reveal nuanced insights into factors shaping their career development. Participants were selected based on their initial intentions to pursue careers other than CS before attending Gatton but changing to a CS focus afterward. Semi-structured interviews conducted via Zoom and coded using thematic analysis provided rich data on lived experiences and perspectives of participants. Findings shed light on the multifaceted factors influencing gifted women’s career intentions before attending Gatton, the transformative effects of the residential STEM program on their decisions to pursue CS careers, and the evolution of their perceptions of CS over time. © The Author(s) 2024.

摘要： The article reflects on the classification of brain tumors where several deep learning (DL) approaches are used. Both primary and secondary brain tumors reduce the patient's quality of life, and therefore, any sign of the tumor should be treated immediately for adequate response and survival rates. DL, especially in the diagnosis of brain tumors using MRI and CT scans, has applied its abilities to identify excellent patterns. The proposed ensemble framework begins with the image preprocessing of the brain MRI to enhance the quality of images. These images are then utilized to train seven DL models and all of these models recognize the features related to the tumor. There are four models which are General, Glioma, Meningioma, and Pituitary tumors or No Tumor model, which helps in reaching a joint profitable prediction and concentrating solely on the strength of the estimation and outcome. This is a significant improvement over all the individual models, attaining a 99. 43% accuracy. The data used in this research was gotten from Kaggle website and comprised of 7023 images belonging to four classes. Future work will focus on increasing the dataset size, investigating additional DL architectures, and enhancing real-time detection to improve the accuracy of diagnostic scans and their overall relevance to clinical practice.

摘要： This article investigates the integration ofVariational Autoencoders (VAEs) and Particle Swarm Optimization (PSO) in the realm of generative art and interactive digital installations. The study focuses on how these advanced algorithms can enhance artistic expression and interactivity, providing novel approaches for generating and optimizing art. Key innovations include the application of VAEs to create diverse and complex art forms, coupled with PSO to fine-tune these generative processes. The research demonstrates that VAEs significantly improve the aesthetic quality and variety of generated artworks, achieving an average aesthetic score of 8.3 out of 10. Integrating PSO further optimizes these results, enhancing the quality of outputs with a final score of 9.0. The study also reveals that this combination improves user engagement and satisfaction, with interactive installations utilizing VAE + PSO achieving a satisfaction score of 9.0, compared to 7.0 for traditional methods. The findings highlight the transformative impact of these algorithms on art generation, showing that while computational resources and time are higher, the artistic and interactive benefits are substantial. This research underscores the potential of combining deep learning and optimization techniques to push the boundaries of digital creativity and offers new perspectives for artists and designers. The article concludes that the synergy of VAEs and PSO represents a significant advancement in generative art and interactive installations, opening new avenues for future exploration and development in the field.

摘要： SQL (Structured Query Language) injection is one of the most prevalent and dangerous forms of cyber-attacks, posing significant threats to database management systems and the overall security of web applications. By exploiting vulnerabilities in web applications, attackers can execute malicious SQL statements, potentially compromising the integrity and confidentiality of critical data. To combat these threats, in this study, we introduce two novel CNN models, SIDNet-1 (SQL Injection-attack Detection Network-1) and SIDNet-2 (SQL Injection-attack Detection Network-2), specifically designed for the classification of SQL injection attacks to bolster web application security. Our comprehensive evaluation includes a comparison of the performance of these customized CNN models against traditional machine learning approaches, highlighting improvements in classification accuracy and reductions in false alarm rates. The proposed models have been experimented with two publicly available dataset SQLI (SQL-Injection) and SQLV2 (SQL-Injection version2). Specifically, SIDNet-1 achieves an impressive accuracy of 98.02% on the SQLI dataset, while SIDNet-2 closely follows with 97.54%. Furthermore, on the SQLIV2 dataset, SIDNet-1 attains 97.77%, and SIDNet-2 achieves 97.83% accuracy respectively.
