CPA auditing is not only a kind of technical activity serving for particular parties, but also systems arrangement for coordinate interests conflict in the capital market. The common belief in the elimination and prevention of fraud is the foundation of CPA audit system. Professional auditors and audit organizations possess skills and positions matching the stock market. The incentive of audit fees and the binding force of audit liabilities both guarantee the self-implementation of audit system. Audit reports signal the fairness of accounting information in simplified forms. CPA audit system also has inherent contradictions. The CPA audit activities should be viewed from a system perspective in order that ideas for the perfection of audit activities can be raised from system construction perspective.展开更多

Various tools and techniques have been applied in trying to curb this problem, however new attacks continue to plague the Internet. We discuss risks that affect web applications and explain how network-centric and host-centric techniques, as much as they are crucial in an enterprise, lack necessary depth to comprehensively analyze overall application security. The nature of web applications to span a number of servers introduces a new dimension of security requirement that calls for a holistic approach to protect the information asset regardless of its physical or logical separation of modules and tiers. We therefore classify security mechanisms as either infrastructure-centric or application-centric based on what asset is being secured. We then describe requirements for such application-centric security mechanisms.展开更多
