style="text-indent:25px">防火墻，它是一種較重要的網(wǎng)絡(luò)防護設(shè)備。從專業(yè)角度講，防火墻是位于兩個(或多個)網(wǎng)絡(luò)間，實施網(wǎng)絡(luò)之間訪問控制的一組組件**。防火墻的本義是指古代構(gòu)筑和使用木制結(jié)構(gòu)房屋的時候，為防止火災(zāi)的發(fā)生和蔓延，人們將堅固的石塊堆砌在房屋周圍作為屏障，這種防護構(gòu)筑物就被稱之為“防火墻”。其實與防火墻一起起作用的就是“門”。如果沒有門，各房間的人如何溝通呢，這些房間的人又如何進去呢？當(dāng)火災(zāi)發(fā)生時，這些人又如何逃離現(xiàn)場呢？這個門就相當(dāng)于我們這里所講的防火墻的“安全策略”，所以在此我們所說的防火墻實際并不是一堵實心墻，而是帶有一些小孔的墻。這些小孔就是用來留給那些允許進行的通信，在這些小孔中安裝了過濾機制，也就是上面所介紹的“單向?qū)ㄐ浴?。我們通常所說的網(wǎng)絡(luò)防火墻是借鑒了古代真正用于防火的防火墻的喻義，它指的是隔離在本地網(wǎng)絡(luò)與外界網(wǎng)絡(luò)之間的一道防御系統(tǒng)。防火可以使企業(yè)內(nèi)部局域網(wǎng)（LAN）網(wǎng)絡(luò)與Internet之間或者與其他外部網(wǎng)絡(luò)互相隔離、限制網(wǎng)絡(luò)互訪用來保護內(nèi)部網(wǎng)絡(luò)。福州防火墻系統(tǒng)方案防火墻采用先進的蠕蟲檢測及阻斷技術(shù)。</p><div
