stack scan 中文意思是什麼
stack scan
解釋
棧掃描-
In the proposed join algorithms, although some algorithms such as mpmgin algorithm [ 23 ], outperform standard rdbms join algorithms, they perform a lot of unnecessary computation and i / o for matching basic structural relationships, especially in the case of parent - child relationships ; other algorithms such as the stack - tree - desc algorithm [ 24 ], represent the state - of - the - art in structural joins, however, they do not utilize indexed structures but sequentially scan the input lists. thus, i / o ' s can be wasted for scanning element that do not participate in the join, and join speed can be influenced
另外，在所提出的演算法中，盡管有的演算法，如mpmgjn演算法[ 23 ]優于標準的rdbms連接演算法，但是該演算法為匹配基本的結構關系，特別是在父子關系情況下，執行了大量不必要的計算和佔用了大量的i / o資源；有的演算法雖然代表了結構連接演算法的先進水平，如stack - tree - desc [ 24 ]連接演算法，但是它沒有利用索引結構而是順序瀏覽輸入列表。 -
Secondly, it can detect opened ports on the basis of results of the first port - scan, and get the information of service and version of these opened ports. thirdly, through many kinds of detecting ways, it can get the os - fingerprints of tcp / ip protocol stack of the destination computer, and guess the faraway operation system exactly. at last, taking cve ( common vulnerabilities and exposures ) as the standard, a more practical vulnerability database by combining the structures of two large - scale oversea vulnerability databases is designed
設計開發的網路漏洞探測系統具有較強的綜合性能，能夠提供多種埠掃描技術，在第一次掃描結果的基礎上對開放的埠進行第二次探測，得到開放的埠的服務和版本信息，通過多種探測方法獲得目標主機的tcp / ip協議棧指紋信息、較準確的推測出遠程操作系統，並以cve （ commonvulnerabilitiesandexposures ）為標準，結合國外兩個大型漏洞數據庫的結構，設計了較實用的漏洞數據庫。
