Multi-Layer and Multi-Aspect Design of CA System Security

摘要：

Security of CA system is a critical component which influences the security in E-Commerce. This paper analyzes the network architecture of CA system, and presents multilayer and multi-aspect security architecture of CA system. This security design focuses on the network layer and application layer. Firewalls divide CA system network into different security grade areas. The following methods are employed in the application layer for security protects: add the sender time stamp in the packets to prevent repeat packets attack;clear to 0 in memory and save as encrypted data in the database for the important data to prevent invalid reading;use central monitor system. The design is employed in a real CA system successfully.
