如何讓您的 SOC 意識到身分的重要性並且有效率地執行工作
攻擊者只需要做對一次就能得手，但資安團隊卻必須每次都做對。這也就是為什麼 SOC 團隊必須防堵勒索軟體攻擊者刺探利用 AD 的脆弱環節。
安全作業中心團隊的成員日以繼夜地輪班，拼了命來防止、偵測和應變網路安全威脅與資安事端。然而在瞬息萬變的威脅版圖中，惡意行動者卻永無休止地攻擊關鍵資產，像是 Active Directory；安全分析師發現，傳統的 SIEM (Security Information and Event Management，安全資訊與事件管理) 解決方案已不足夠。試想，主要的勒索軟體操控者 (例如：LockBit 2.0、Conti 和 BlackMatter) 全都是利用 AD 來引入或傳播惡意軟體。
SOC 團隊仰賴 SIEM 解決方案來彙整與關聯分析來自整個企業 IT 基礎架構資產的記錄檔和其他資料，包括 AD 在內。雖然 SIEM (安全資訊與事件管理) 是一個強大的解決方案，通常可用來監視網路基礎架構，但它並非針對 AD 安全這類目的所設計。
SOC 團隊所面臨的主要挑戰包括：
誤報： SOC 的分析師難以對付 SIEM 解決方案所產生的大量警示，然後從中精確地找出少數真正關鍵的事件。因此，SOC 團隊花費了太多時間評估無以計數的錯誤警告，影響了他們有效解決真正威脅的能力。
難以防止後門程式產生： 近期的勒索軟體攻擊顯示，駭客愈來愈清楚他們能夠透過刺探利用錯誤設定和建立後門程式，輕易地取得受害者 AD 環境毫無限制的存取權限。戰勝此類威脅所需的能力遠超過 SIEM 所能提供。
讓 SIEM 長智慧
SOC 團隊如何取得 AD 更高的能見度，讓他們更善於偵測威脅，而不致讓威脅從傳統 SIEM 解決方案的缺口中溜進來？
專為 AD 所設計的解決方案 (如 Tenable.ad) 不只能填補傳統 SIEM 解決方案的缺口，還能與 SIEM 整合，以提升 AD 安全性和 SOC 的工作效率，進而強化整個企業的網路安全態勢。Tenable.ad 能為您的 SIEM 增添「AD 情報」以免除誤報，並專注於必須立刻解決的重大弱點。有了 Tenable.ad，SOC 團隊就能大幅提高生產力與效率，並強化其 AD 環境的安全性。
