从硬件级别实施网络安全

Implementation of Network Security on Level of Hardware

网络安全是网络建设中的重要内容.网络安全包括硬件安全和其上的软件的安全.网络硬件主要包括网络互连设备,比如集线器、交换机、路由器等,以及硬件防火墙.从硬件级别上实施网络安全,必须安全配置网络设备.在交换机上进行VLAN的配置,在路由器上进行ACL的配置,在防火墙上进行过滤规则的配置.只有网络硬件上进行了安全配置,网络软件才有可能发挥作用.

Network security is very important in the construction of network, it includes hardware .security and software security. The network hardware includes the network interconnecting devices, such as HUB, switch, muter and so on, as well as hardware firewall. The network interconnecting devices must be configured securely so that the network security is implemented on the level of hardware. VLAN is configured on the switch, and ACL is configured on the muter, and filter-rule is configured on the firewall. The network software can not function until the network devices are configured securely.
