    • An auditing system is disclosed comprising a Policy Validation Mechanism Program (PVMP) that operates in conjunction with a Workflow Engine (WE), and a Policy Validation Server Program (PVSP) that operates on a Policy Validation Server (PVS) connected to the WE by a secure communication link. The PVMP converts a workflow to a workflow representation (WR) and sends the WR to the PVS. The PVSP compares the steps in the WR to a security policy identified for that WR and determines whether the WR is in compliance. In addition, the PVSP validates a checksum for the WR and logs the checksum for subsequent comparisons. The PVSP uses the checksum to determine whether a policy has changed during execution of the workflow. If the WR is not in compliance, if the checksum cannot be validated, or if a policy has changed, then a failure notification is sent to the WE. Otherwise, a success notification is sent to the WR.
    • 公开了一种审计系统,其包括与工作流引擎(WE)一起操作的策略验证机制程序(PVMP)以及在通过以下方式连接到WE的策略验证服务器(PVS)上运行的策略验证服务器程序(PVSP) 一个安全的通信链路。 PVMP将工作流转换为工作流表示(WR),并将WR发送到PVS。 PVSP将WR中的步骤与为该WR标识的安全策略进行比较,并确定WR是否符合要求。 此外,PVSP验证WR的校验和,并记录校验和以进行后续比较。 PVSP使用校验和来确定在执行工作流程期间策略是否已更改。 如果WR不合规,如果校验和无法验证,或策略已更改,则向WE发送故障通知。 否则,将向WR发送成功通知。
