@article{18, author = {Yu Zheng and Zheng Li and Xiaolong Xu and Qingzhan Zhao}, title = {Dynamic defenses in cyber security: Techniques, methods and challenges}, abstract = {we conduct a comprehensive and concrete survey of recent research efforts on dynamic defense in cyber security. Specifically, we firstly introduce basic concepts and define dynamic defense in cyber security. Next, we review the architectures, enabling techniques and methods for moving target defense and mimic defense. This is followed by taxonomically summarizing the implementation and evaluation of dynamic defense. Finally, we discuss some open challenges and opportunities for dynamic defense in cyber security.}, year = {2022}, journal = {Elsevier BV}, month = {2022-08}, issn = {2352-8648}, url = {https://www.sciencedirect.com/science/article/pii/S235286482100047X}, doi = {10.1016/j.dcan.2021.07.006}, note = {With the rapid development of various computing paradigms, information resources are widely shared and fully utilized. Consequently, cyber security problems are aggravated. To cope with this challenge, moving target defense and mimic defense are investigated to improve the defense effect. Furthermore, improving dynamic defense system construction has important theoretical guidance and practical significance for improving network active defense capability.}, }
