數(shù)據(jù)庫防火墻顧名思義是一款數(shù)據(jù)(庫)安全設(shè)備,從防火墻這個詞可以看出,其主要作用是做來自于外部的危險隔離。換句話說,數(shù)據(jù)庫防火墻應(yīng)該在入侵在到達(dá)數(shù)據(jù)庫之前將其阻斷,至少需要在入侵過程中將其阻斷。
1. 如何定義外部? 至于如何定義外部威脅,則需要對于數(shù)據(jù)庫邊界進(jìn)行明確的界定,而這個數(shù)據(jù)庫邊界的界定則具有多變性。第一種定義,從極限的角度來看,由于現(xiàn)在網(wǎng)絡(luò)邊界的模糊,可以把所有來自于數(shù)據(jù)庫之外的訪問都定義為外部。如果是這個定義來看,防火墻承載的任務(wù)非常繁重,可能不是一個安全設(shè)備所能夠承擔(dān)的。第二種定義是數(shù)據(jù)中心和運維網(wǎng)絡(luò)可以被定義為內(nèi)部訪問,其他訪問定義為外部訪問,讓防火墻不需要去承載內(nèi)部運維安全和員工安全,從而更好的工作。 綜合看來,我們采用第二種定義,數(shù)據(jù)庫防火墻主要承載數(shù)據(jù)中心和運維網(wǎng)絡(luò)之外的數(shù)據(jù)(庫)安全工作。 2. 如何定義數(shù)據(jù)庫防火墻? 一旦準(zhǔn)確的定義了什么是外部之后,什么是數(shù)據(jù)庫防火墻就比較清楚了。運維網(wǎng)絡(luò)之外的訪問我們都可以定義為業(yè)務(wù)訪問。
數(shù)據(jù)庫防火墻是一款抵御并消除由于應(yīng)用程序業(yè)務(wù)邏輯漏洞或者缺陷所導(dǎo)致的數(shù)據(jù)(庫)安全問題的安全設(shè)備或者產(chǎn) Siemens Simatic S5 6ES5946-3U?A22 6ES5-946-3?UA22 Siemens Simatic 6ES7331-7K?F01-0AB0
