As a recently introduced and rapidly accepted new network technology, software defined networking (SDN) provides network providers with operational agility and reduction in capital and operational expenses. As with all new technologies, especially one that offers rich operational flexibility, the lack of experience makes it vulnerable to potential misuse or malicious activities. As SDN becomes the technology of choice of network and service providers, it is imperative that careful attention is paid to the technology's vulnerability and proper mechanisms to protect SDN-based deployment environments. This article presents a classification of vulnerability challenges for SDN and discusses several solution strategies to address these challenges.

软件定义网络的漏洞挑战


作为最近推出并迅速被接受的新型网络技术，软件定义网络 (SDN) 为网络提供商提供了运营灵活性并减少了资本和运营支出。与所有新技术一样，尤其是提供丰富操作灵活性的新技术，缺乏经验使其容易受到潜在的误用或恶意活动的影响。随着 SDN 成为网络和服务提供商的首选技术，必须认真关注该技术的漏洞和适当的机制来保护基于 SDN 的部署环境。本文对 SDN 的漏洞挑战进行了分类，并讨论了应对这些挑战的几种解决方案策略。
