傳統(tǒng)的網(wǎng)絡(luò)安全解決方案通常是被動(dòng)防御，事后補(bǔ)救。網(wǎng)絡(luò)準(zhǔn)入控制則從用戶終端入手，整合網(wǎng)絡(luò)接入控制與終端安全產(chǎn)品，通過安全客戶端、安全策略服務(wù)器、網(wǎng)絡(luò)設(shè)備以及第三方軟件的聯(lián)動(dòng)，對(duì)接入網(wǎng)絡(luò)的用戶終端強(qiáng)制實(shí)施安全策略，嚴(yán)格控制終端用戶的網(wǎng)絡(luò)使用行為，可以加強(qiáng)用戶終端的主動(dòng)防御能力，提高整個(gè)

It implements security policy and control End-User's behaviors strictly through cooperating with security client, security policy server, network device and third party software. This solution can enhance End-User's defense power and improve the whole network security.
