主機的入侵檢測系統 (HIDS)簡介

主機的入侵檢測系統 (HIDS) 是什麼意思?

主機的入侵檢測系統 (HIDS) 是一種系統,它監控安裝它的電腦系統以檢測入侵和/或濫用,並通過記錄活動並通知指定機構來響應。HIDS 可以被認為是一個代理,它監視和分析是否有任何東西或任何人,無論是內部還是外部,是否繞過了系統的安全策略。

Techopedia 解釋基於主機的入侵檢測系統 (HIDS)

入侵檢測系統 (IDS) 是一種軟體應用程式,可分析網絡中的惡意活動或違反策略並將報告轉發給管理層。IDS 用於使安全人員了解進入和離開受監控網絡的數據包。有兩種一般類型的系統:基於主機的 IDS (HIDS) 和基於網絡的 IDS (NIDS)。

NIDS 通常是包含網絡檢測功能的獨立硬體設備。它通常由位於網絡各個點的硬體傳感器組成。它還可能包含安裝在沿網絡連接的各種電腦上的軟體。NIDS 分析入站和出站數據包並提供實時檢測。

HIDS 分析進出安裝入侵檢測軟體的特定電腦的流量。基於主機的系統還能夠監控關鍵系統文件以及覆蓋這些文件的任何嘗試,這可以應用在有SEO優化的wordpress網站主機上,wordpress很容易被入侵以及攻擊,有HIDS即可以隨時監控流量。

但是,根據網絡的大小,部署 HIDS 或 NIDS。例如,如果網絡規模很小,那麼 NIDS 的實施通常更便宜,並且與 HIDS 相比,它需要更少的管理和培訓。然而,HIDS 通常比 NIDS 更通用。
