本文档概述了与NFV相关的开源管理软件的安全特性，尤其是OpenStack™ [i.1]作为第一个案例研究。它介绍了提供安全服务（如身份验证、授权、机密性保护、完整性保护和日志记录）的OpenStack模块，以及它们各自依赖关系的完整图形，直至实现加密协议和算法的图形。它还确定了一组与NFV相关的OpenStack的使用和增强建议。

The present document gives a survey of the security features in the open source management software relevant to NFV, in particular OpenStack™ [i.1] as the first case study. It addresses the OpenStack modules that provide security services (such as authentication, authorization, confidentiality protection, integrity protection, and logging) together with the full graphs of their respective dependencies down to the ones that implement cryptographic protocols and algorithms. It also identifies a set of recommendations on the use of and enhancements to OpenStack as pertinent to NFV.
