Global Security Network Design And Implementation

Information technology continues to advance, making network construction industries are maturing, the completion of construction of basic network architecture, a variety of business applications on-line, making the construction of network security put on the network construction of the main agenda.To make the campus network more secure and stable. Universities usually invest lae sums of money, purchasing a lae number of security devices and software, such as firewalls, antivirus walls, proxy servers, asset management software, anti-virus software to manage their network security and maintenance, but it is easy to see that These are mainly used for the deployment of hardware and software against external attacks, but often overlooked in network security for the protection and control. Even these security hardware, software, a simple pile of conflicts, but also can not play the effect of 1+1= 2, many features repeat, there are many features short, this is undoubtedly a huge security investment to play its role can not be.Most of ARP implementation NAC 802.1x technology combined with the method, mainly used in major IDC, most of the aid management, such as a security state can not meet the network needs, they can take "physical" means "health" to meet the conditions of the host before accessing the network.Significance of this project is to introduce the most to the idea NAC to address network security in the Construction of low return on investment, network security problems not obvious transformation.
