EPM 策略:如何攔截基於特權的攻擊

核心洞察

  • 大多數端點入侵成功的原因在於特權濫用,而非技術性漏洞。
  • 身分是新的防禦邊界;端點特權是攻擊者橫向移動的「核心目標」。
  • 端點特權管理 (EPM) 可對特權在運行時「如何」及「何時」被使用進行精細控制。

六大主要的特權攻擊向量

攻擊者依賴過度授權與管理盲點來推進其目標。常見技術包括:

本地特權提升 (LPE)
利用漏洞從標準使用者帳戶提升至完整的管理員存取權限。
憑證竊取
從記憶體中提取憑證(如使用 Mimikatz),以便跨系統冒充使用者。
離地攻擊 (LotL)
濫用 PowerShell 和 WMI 等受信任的系統工具,在不被察覺的情況下執行惡意操作。
濫用本地管理員權限
透過受侵害的管理員帳戶,獲得對系統設定和敏感數據的無限制控制權。
無檔案與腳本攻擊
利用提升的權限直接在記憶體中執行惡意代碼,規避磁碟鑑識。
應用程式誤用
利用受信任的應用程式情境,透過修改過的二進位檔案繞過安全控制。

現代企業的縱深防禦:混合環境下的演進策略

關鍵亮點(安全領導者的快速總結)

  • 混合環境會產生盲點。本文將揭示攻擊者在雲端、本地和遠端存取工作流程中利用的確切漏洞。
  • 身份現已成為最強大的控制點。您將了解零信任 (Zero Trust)、多重因素驗證 (MFA) 和統一存取策略如何立即減少基於憑證的洩露。
  • 端點暴露出最大的風險。本文將解釋 XDR 和端點特權管理 (EPM) 如何阻止橫向移動並保護移動設備和筆記型電腦上的憑證。
  • 網絡存取需要更嚴格的控制。您將看到 ZTNA、分段和遠端 PAM 如何限制攻擊者在混合網絡內的移動。
  • 快速響應現需要自動化。本文將展示 AI 驅動的偵測和 SOAR 如何將遏制時間從數天縮短到數秒。

 

為何傳統縱深防禦需要現代化改造

2024 年 2 月發生的 Change Healthcare 網絡攻擊——美國歷史上最大的醫療保健數據洩露事件——是現代失敗的一個完美例證。攻擊者利用遠端存取伺服器上缺乏多重因素驗證的漏洞,使用竊取的憑證,然後透過遺留系統進行橫向移動。此次事件的應對成本高達 28.7 億美元,這表明縱深防禦 (DiD) 仍然至關重要,但必須針對混合環境進行徹底演進。

傳統的 DiD 假設有清晰的網絡邊界,但兩個根本性的變化打破了這一假設:

消失的邊界:分散式工作負載和用戶

由於混合雲採用(IaaS、PaaS、SaaS)和加速的遠端工作,邊界已經消失。員工從不受信任的家庭網絡和公共 Wi-Fi 存取企業資源,形成了「無處不在的工作者」。這將攻擊面分散到雲端平台、移動端點和物聯網設備上,使企業無法再防守單一邊界。

演變中的威脅行為者 TTPs 針對混合漏洞

攻擊者已迅速開始利用混合環境中的漏洞。威脅行為者不再需要猛攻單一防火牆;他們可以針對本地、雲端或遠端組件中最薄弱的環節發起攻擊。

多雲的複雜性通常會導致安全控制措施支離破碎和策略不一致。攻擊者利用任何此類不一致性,透過最不安全的環境進入。由於傳統安全工具難以在這種流動的地形中提供統一的可見性和控制,攻擊者可以從一個立足點(例如一個 SaaS 帳戶)轉而攻擊本地伺服器。

現代化 DiD 安全模型的核心原則

原則 1:假設洩露,實施零信任和強大的 MFA

哲學必須從隱式信任轉向處處顯式驗證。您的現代 DiD 必須以「假設洩露」的心態運作,並據此設計控制措施。這是零信任架構的精髓。身份取代了網絡位置成為主要的控制平面,使得多重因素驗證 (MFA) 對所有用戶來說都是不可妥協的。

原則 2:跨所有環境的全面可見性

實現「單一管理介面」來關聯來自雲端工作負載、SaaS 應用程式、本地伺服器和端點的事件至關重要。碎片化的監控會直接導致錯失威脅和延遲事件響應,因為攻擊者可以在監控系統的間隙中橫向移動而不被察覺。您必須投入資源於打破安全孤島的工具,並擴展 SIEM 以接收所有領域的日誌。

原則 3:以數據為中心——保護最重要的資產

現代 DiD 優先保護數據本身,而不僅是圍繞它的基礎設施。解決方案是以數據為中心的安全策略:首先對關鍵數據進行分類,然後在其整個生命週期中,在盡可能靠近數據的地方應用多層保護。這包括強大的加密、標記化以及嚴格的存取控制,確保即使其他層級失敗,數據仍然受到保護或無法使用。

原則 4:自動化與協調

自動化和協調對於一致地執行安全策略和快速響應威脅至關重要。現代 DiD 架構利用技術將各層連接起來,使其作為一個協調的整體運作。最終目標是實現自主安全態勢,透過協調混合基礎設施中的遏制行動,在數秒內而非數天內對網絡威脅做出反應。

 

重新架構您的層次:可操作的策略

 

基礎階段:身份、存取和端點安全

  • 身份管理: 部署雲原生身份供應商並建立全面的特權存取管理 (PAM) 與即時權限提升。像 Segura® 這樣的下一代 PAM 平台可減少不必要的常駐權限,並應用一致的技術控制。
  • 端點安全: 為所有設備(筆記型電腦、智能手機)部署 擴展偵測與回應 (XDR) 和 端點特權管理 (EPM)。保持積極的修補管理並實施移動威脅防禦。
  • 安全網絡結構: 用 零信任網絡存取 (ZTNA) 取代廣泛的 VPN 存取。實施微隔離以防止橫向移動,並擴展遠端 PAM 以用於外部用戶。

保護階段:應用程式安全、數據保護和實體安全

  • 應用程式和 API 安全: 將自動化安全測試嵌入到 DevSecOps 管道中。部署 Web 應用程式防火牆和 API 網關來監控所有請求並實施運行時應用程式自我保護 (RASP)。
  • 以數據為中心的保護: 使用自動化數據發現和分類。部署策略性加密(包括機密運算)並使用資料外洩防護 (DLP) 來監控數據移動。

情報階段:自動化偵測和文化

  • AI 驅動的威脅偵測: 部署 AI 驅動的 SIEM 平台,匯總來自所有環境的日誌。實施 安全協調、自動化和響應 (SOAR) 工具以觸發協調的遏制行動。
  • 安全意識文化: 建立持續的安全意識,以應對混合工作現實(保護家庭網絡、識別社交工程)。

 

結論:戰略性下一步

在現代企業中實施 DiD 需要重新思考安全措施,以適應一個沒有邊界的世界,將身份和數據置於中心,並將自動化貫穿始終。

Segura® 的全面 PAM 平台 為現代縱深防禦提供了基石,提供完整的特權存取生命週期覆蓋,且部署速度比傳統解決方案顯著更快。透過同時解決多重 DiD 保護,Segura® 大幅降低了基礎設施要求。

Enterprise Guide to Decentralized Identity: Preparing for Verifiable Credentials and DIDs

 

 

Key Insights: Decentralized Identity for the Enterprise

  • Decentralized identity shifts control from vulnerable databases to user-owned DIDs and verifiable credentials (VCs), significantly reducing breach impact and compliance risk.
  • Enterprises gain faster, higher-trust verification for customers, employees, and partners—without the liability of storing sensitive personal data.
  • This model accelerates zero-trust maturity and replaces friction-heavy onboarding with instant, cryptographically proven identity.
  • Early adopters gain a security and efficiency advantage, evolving from identity providers to identity verifiers prepared for the next era of digital trust.

Introduction: The Shift to Digital Trust

Imagine tapping your phone once at a rental car counter to instantly prove driving eligibility without revealing your address or full birth date. This is the reality of decentralized identity. Current identity systems force users to juggle passwords and encourage reuse, contributing to a 71% jump in credential-based attacks. Meanwhile, every corporate breach spills millions of sensitive records.

The alternative—Self-Sovereign Identity (SSI)—is emerging, driven by governments and industry. CISOs must prepare for Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to future-proof their security architecture.

What Are Decentralized Identifiers (DIDs)?

Today, third parties control your digital identity (HR issues your badge, banks issue account numbers). Decentralized Identifiers (DIDs) flip this model. A DID is a persistent, globally unique identifier that you own and control via cryptographic keys. Nobody can create or take away your DID.

Security Impact: Attackers favor centralized databases because one breach yields massive payouts. With DIDs, the sensitive identity information is distributed across individual digital wallets, forcing attackers to target individual endpoints—a much less scalable endeavor.

How Verifiable Credentials (VCs) Work

Like a physical driver’s license or diploma, a Verifiable Credential (VC) proves something about you. VCs are digital and highly secure because they carry a digital signature from the issuer (e.g., your university or the DMV). Anyone can check this signature instantly.

Crucially, VCs improve privacy. Unlike a physical license which reveals everything, a digital VC can use zero-knowledge cryptography to prove, for example, “This person is over 21” without exposing the address, full name, or exact birth date.

The Trust Triangle:

  • Issuers: Create and digitally sign the VCs (e.g., your employer). They publish their public key for verification.
  • Holders (You): Store VCs in a digital wallet and decide precisely when to share them.
  • Verifiers: Check the VC’s cryptographic signature when you present it (e.g., a hiring manager). They get instant proof without needing to call the Issuer.

Enterprise Benefits of Decentralized Identity Adoption

1. Faster and Stronger Identity Verification

VCs simplify slow customer and employee onboarding. Instead of manual document checks and phone calls, enterprises accept credentials that come pre-verified. This translates to faster customer onboarding (fewer abandoned processes), quicker employee verification (faster productivity), and higher accuracy (digital credentials are harder to fake than paper).

2. Lower Risk and Reduced Data Liability

Decentralized identity tackles the “honeypot” problem. Instead of hoarding sensitive data (passports, SSNs) to authenticate users, VCs allow you to verify information without storing it permanently. This dramatically reduces your attack surface and shrinks your compliance burden under privacy regulations.

3. User Experience Improvements

Users gain control and trust when they manage their own credentials. Replacing account creation and passwords with presentation of a trusted credential from a digital wallet is faster and more secure. This also facilitates passwordless authentication.

Roadmap: Implementing Decentralized Identity

Phase 1: Strategy and Education (Now – 12 months)

Action: Educate security, IT, and compliance teams on DIDs and VCs. Identify areas where decentralized identity could solve key bottlenecks, such as customer onboarding or employee credential verification. Engage with industry standards groups like the W3C.

Phase 2: Piloting VCs in Real Use Cases (12 – 24 months)

Action: Select one high-value, manageable use case (e.g., digital degree verification for a specific department). Define clear success metrics (faster verification, happier users). Partner with a vendor or use open source tools to build prototype systems for issuance or verification. Document integration challenges.

Phase 3: Integrating DIDs into IAM and Zero Trust (24+ months)

Action: Plan broader integration with existing IAM infrastructure. Build trust registries (determining which issuers to trust). Update user-facing flows to handle “Sign in with Digital ID.” Focus on handling both new and legacy authentication methods smoothly. This aligns perfectly with a Zero Trust approach by continuously verifying credentials for every access request.

Challenges and Considerations

  • User and Issuer Adoption Gap: Early adoption will be fragmented. Focus on credentials likely to be universally accepted soon (e.g., government digital IDs) and be patient during the transition period.
  • Governance and Trust: Decentralization requires a new governance framework to determine which external issuers to trust and how to handle key compromises or policy changes.
  • Interoperability: Ensure chosen vendors prioritize standards compliance to prevent creating new, incompatible silos.
  • Legacy Integration: Budget resources to build middleware that translates verifiable credential assertions into attributes compatible with existing systems (Active Directory, LDAP, etc.).

Conclusion: Turning Recognition Into Results

Digital identity is moving from centralized control toward decentralized trust. CISOs and enterprise security leaders have an opportunity to lead this transition. Organizations that prepare now will be better positioned to capitalize on security, privacy, and efficiency benefits.
