就目前我国互联网的发展态势以及具体应用来看,ADSL因具有下行速率高、频带宽、性能优等特点成为继Modem、ISDN之后的一种全新更快捷、更高效的接入方式,可以在校园网的建设中得到广泛实用。同时,由于在校园网建设过程中,设备相对简陋,资金人力投入不足而暴露出的安全问题也不容小觑,为了解决这些安全问题,各种安全机制、策略和工具需要综合利用。 At present, the development trend of the Internet in our country and the specific application of view, ADSL has become a new faster, more efficient access mode after Modem, ISDN because of the downlink rate is high, the bandwidth is good, the superior performance characteristic, can be in the campus network The construction is widely used. At the same time, due to the relatively simple equipment in the process of building a campus network, the security problems exposed by the lack of funds and manpower can not be underestimated. In order to solve these security problems, various security mechanisms, strategies and tools need to be comprehensively utilized.
