Abstract
Transfer learning plays a vital role in enhancing cybersecurity measures by addressing data scarcity and improving model performance. This paper explores the applications of transfer learning in various security functions, such as policy training, anomaly detection, and electronic forensics. It discusses key challenges like imbalanced class distribution, new attack labels, adversarial robustness, confirmation bias, ethical risks, fairness issues, data privacy concerns, and integration with federated learning (FL) and reinforcement learning (RL). The research directions include dealing with imbalanced class distribution using generative models, privacy-preserving transfer learning methods, multi-source domain adaptation approaches for security tasks, integration with federated learning (FL), and reinforcement learning (RL) for optimal strategy identification.
