python攻擊區域網電腦 區域網攻擊

目錄 區域網內的欺騙攻擊主要有以下幾種 arp欺騙 dns欺騙 netbios名稱欺騙和llmnr欺騙 進行內網攻擊的第一步是先檢視我們自己網絡卡的配置資訊，從而得知內網網段的資訊。探測內網資訊 檢視自己網絡卡配置資訊有好多命令，常用的有下面幾個，我們主要是檢視ip 子網掩碼和閘道器資訊 nmcli...

區域網是什麼 區域網的介紹

區域網 local area network，l是指在某一區域內由多台計算機互聯程式設計客棧成的計算機組。一般是方圓幾千公尺以內。區域網可以實現檔案管理 應用軟體共享 印表機共享 工作組內的日程安排 電子郵件和傳真通訊服務等功能。區域網是封閉型的，可以由辦公室www.cppcns.com內的兩台計算...
