X9。134是一个由多个部分组成的标准，解决了可互操作和安全的系统，用于提供、操作和管理移动金融服务（MFS），包括开发和操作移动应用程序（app）以提供MFS（包括移动银行）的安全要求。这是X9。134标准不是认证标准。本标准第2部分旨在帮助MFS开发人员和MFS提供商（MFSP）评估和选择MFS的安全机制，以便根据MFSP设计、记录、实施和维护的安全策略进行管理。对于MFS用户来说，了解安全要求和其他考虑因素如何影响移动环境也很重要。

X9.134 is a multi-part standard addressing interoperable and secure systems for the provision, operation, and management of a Mobile Financial Service (MFS), including the security requirements for development and operation of a mobile application (app) to deliver an MFS, including mobile banking. This X9.134 standard is not a certification standard. This Part 2 of the standard is intended to assist MFS developers and MFS providers (MFSPs) to evaluate and select security mechanisms for an MFS to be managed according to a security policy designed, documented, implemented, and maintained by the MFSP. It is also important for users of an MFS to understand how security requirements and other considerations factor into the mobile environment.
