style="text-indent:25px">防火墻，它是一種較重要的網(wǎng)絡(luò)防護(hù)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(shí)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(jiān)固的石塊堆砌在房屋周圍作為屏障，這種防護(hù)構(gòu)筑物就被稱之為“防火墻”。其實(shí)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(jìn)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(shí)際并不是一堵實(shí)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(jìn)行的通信，在這些小孔中安裝了過濾機(jī)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(hù)內(nèi)部網(wǎng)絡(luò)。蚌埠防火墻軟件</p><p
