Special Issue Information

Dear Colleagues,

With mobile software applications increasingly affecting our lives and societies, their security and privacy issues have received growing attention in the research community, particularly techniques utilizing data-driven, notably machine/deep learning, methods having demonstrated tremendous potential in recent years, a major challenge being that such solutions tend to not be sustainable because of the moving defense targets; that is, a technique devised to work effectively for one population of mobile applications developed in a certain period of time may not work well for applications coming out later in time, because of the constant evolution of the population. This Special Issue is dedicated to exploring and discovering more sustainable novel solutions so that we can eliminate the need to repeatedly and frequently develop/update techniques for newer mobile application populations; in fact, even if it is affordable to do so, we may not have newer samples available for re-training/updating the previously trained learning models. The topic pursues a synergy between sustainable mobile software security and robust data-driven (especially AI/ML) models, where the symmetry concept is reflected between sustainability in the former and robustness in the latter, this Special Issue collecting papers that highlight the recent advances and broad research efforts tackling the challenge of technique deterioration, the lack of training samples that represent new/emerging software applications, and the subsequent proliferation of zero-day security breaches.

Recent developments have made software-defined networking (SDN) a popular technology for solving the inherent problems of conventional distributed networks. The key benefit of SDN is the decoupling between the control plane and the data plane, which makes the network more flexible and easier to manage. SDN is a new generation network architecture; however, its configuration settings are centralized, making it vulnerable to hackers. Our study investigated the feasibility of applying artificial intelligence technology to detect abnormal attacks in an SDN environment based on the current unit network architecture; therefore, the concept of symmetry includes the sustainability of SDN applications and robust performance of machine learning (ML) models in the case of various malicious attacks. In this study, we focus on the early detection of abnormal attacks in an SDN environment. On detection of malicious traffic in SDN topology, the AI module in the topology is applied to detect and act against the attack source through machine learning algorithms, making the network architecture more flexible. Under multiple abnormal attacks, we propose a hierarchical multi-class (HMC) architecture to effectively address the imbalanced dataset problem and improve the performance of minority classes. The experimental results show that the decision tree, random forest, bagging, AdaBoost, and deep learning models exhibit the best performance for distributed denial-of-service (DDoS) attacks. In addition, for the imbalanced dataset problem of multiclass classification, our proposed HMC architecture performs better than previous single classifiers. We also simulated the SDN topology and scenario verification. In summary, we concatenated the AI module to enhance the security and effectiveness of SDN networks in a practical manner. Full article
