Sarama says the main challenge he’s having is that the standard is a moving target. For instance, last autumn, the PCI Security Standards Council made some changes to retention requirements that affected CheckFree. Now, an {audit trail} of all access to cardholder data and network resources must be available online for three months and offline for another nine months, which means that CheckFree has to invest in additional online storage devices.
Sarama说，他现在面临的主要难题是，这项标准在不断变化中。譬如说，去年秋天，PCI安全标准委员会对数据保留要求作了一些变动，这影响了CheckFree。现在，访问持卡人数据和网络资源的所有｛审查追踪记录｝都必须在线保存三个月、另外离线保存九个月，这意味着CheckFree必须购买额外的在线存储设备。
不知“记录”两个字加得是否准确？
