This paper deeply analyses the properties, application conditions and v aried policy combinations of seven POA standard policies. Based on the analysis, we design and implement a POA policy mechanism, provide the way of flex  ible policy creation and policy management, make the application developers flexibly and dynamically configure POA according to the requirements, and th us satisfy the requirements of different applications.
