CIS18勒索軟體合規性

透過 BullWall 的自動化圍堵,實現 CIS v8 勒索軟件防禦韌性

CIS 控制措施 v8(CIS Controls v8)為網絡防禦提供了關鍵的路線圖,但它也僅僅是一張地圖。當勒索軟件攻擊執行時,合規性查檢表幾乎無法提供任何保護。關鍵問題變成了:您該如何即時阻止攻擊?

這正是 BullWall 為填補此缺口而生的目的。

BullWall 的勒索軟件圍堵平台專注於一件事:立即阻止進行中的勒索軟件攻擊。透過在未經授權的加密行為開始的瞬間進行偵測與阻止,BullWall 活化了 CIS 控制措施的原則,將指導方針轉化為自動化的即時防禦。它直接支援多項 CIS 安全防護措施,在最關鍵之處強化您的防禦韌性。

控制措施 10:惡意軟件的最後一道防線 (安全防護措施 10.1, 10.4)

CIS 建議部署標準的反惡意軟件解決方案。但如果它們失效了呢?現代的勒索軟件被設計來規避基於特徵碼、甚至是傳統的 EDR 工具。

BullWall 扮演了至關重要的最後一道防線。它專注於未經授權的加密「行為」—— 這是任何勒索軟件的最終目標 —— 從而阻止那些已繞過您邊界和端點預防層的攻擊。這在黑客滲透之後、造成損害之前,提供了一項關鍵的圍堵能力。

控制措施 17:革新事故應變 (安全防護措施 17.3, 17.4, 17.5)

這是 BullWall 提供其最重要價值的地方。典型的勒索軟件事故應變可能需要數小時,這足以讓攻擊擴散。BullWall 將應變時間縮短至數秒。

  • 自動化應變:平台能即時偵測加密行為、識別來源,並隔離受感染的設備以防止橫向移動。
  • 可操作情報:它將即時日誌和警報傳送至 SIEM / SOAR 系統(17.3),並提供關於攻擊來源和目標檔案的鑑識數據,以供事後分析(17.5)。
  • 擬真測試:BullWall 可用於紅隊演練,以驗證您的事故應變計畫是否能真正阻止一場即時的加密事件(17.4)。

控制措施 13:堅守資料保護 (安全防護措施 13.1)

雖然 BullWall 並非資料分類工具,但其主要功能直接保護您最關鍵的資產:資料。透過防止未經授權的加密,BullWall 確保敏感與機密資訊的可用性與完整性,有效阻止攻擊者利用您的資料作為勒索籌碼。

控制措施 18 & 16:驗證與緩解真實世界風險 (間接支援 18.1 及應用程式安全)

滲透測試(18.1): BullWall 讓滲透測試人員能夠驗證您的組織對即時加密攻擊的實際應變能力,超越理論上的漏洞掃描,測試真實世界的防禦韌性。

應用程式安全(16): 如果應用程式的漏洞被利用來發動勒索軟件,BullWall 能確保惡意酬載無法達成其加密檔案的目標,從而減輕衝擊。

總結:BullWall 對 CIS 控制措施的貢獻
