Abstract:

This paper is based on the peace city network video monitoring system, by a detailed research; check the present situation and problems, follow the method of system safety analysis, proposed the solutions and improvements. The article firstly puts forward the principles and methods of security domain division, and divides the system into four security zones: network core domain, business computing domain, public service domain and client domain; then describe the optimization countermeasures of system security enhancement. The main methods are as follows: take advantage of dual PE redundant backup strategy reinforce the network core performance, network firewall deployment, implement intrusion prevention system. Finally summarizes and prospect for the solution of the network video monitoring system.

Key words: MPLS, VPN, network monitoring system, security enhancement
