Realization Of Information Security In Bank's Network System

The security of bank's network system concerns to the security of the whole financial system, in order to guard against and defuse financial risks, we must ensure the security of it. As the increasing of bank's network application level, the potential safety hazard is also increasingly exposed, how to build an efficient and safety bank network information system has become a reality and urgent problems. It is a system engineering to build a security system of bank's network; we should consider it synthetically from several aspects, such as policies, technologies and managements. The security assurance of bank's network should consider form four aspects; they are information protection, detection, response and recover. The author based on the theory of information security, and researches how to protect the security of bank's network and hopes to achieve it at work, also give certain reference and guidance to the construction of bank's network security system.This paper expounds the network security knowledge and system concretely, gives a deeply discussion of network information security, analysis the risks that threat to the protection of bank's network information security, also research some key technologies, such as encryption, firewall, intrusion detection, VLAN, access control, scanning loopholes. Based on the researching, the author combines the specific characteristics of network information security protection in the bank, from encryption technology and application and realization of digital signature technology, firewall machine configuration and realization of heat, vulnerability scanning system and the deployment of the intrusion detection system, access control, through several aspects of the actual deployment, configuration and the implementation of network information security and protection to the bank.Finally, this paper analyses the importance of protect target, threaten and vulnerability, as well as the effectiveness of the safety measures. Comprehensive analysis the potential risks, and put forward suggestions of risks control in order to protect network information system effectively.
