探索 SaaS 安全迷宮：令牌安全和安全團隊的角色

SaaS 違規事件急劇增加，通常是由代幣盜竊造成的。了解安全團隊如何加強令牌衛生並防禦這些不斷變化的威脅。

The SaaS landscape is booming, but so are the breaches. Token theft is a leading culprit, making robust security measures more critical than ever.

SaaS 領域正在蓬勃發展，但違規行為也在蓬勃發展。令牌盜竊是罪魁禍首，因此強大的安全措施比以往任何時候都更加重要。

The Rising Tide of SaaS Breaches: A Token-Centric View

SaaS 違規浪潮的興起：以代幣為中心的觀點

We're living in a SaaS-ified world. Companies rely on a multitude of SaaS applications, but this dependence introduces vulnerabilities, particularly around tokens – those small pieces of data that act as keys to these applications. A compromised token can grant cybercriminals easy access, bypassing even multi-factor authentication (MFA). Recent breaches highlight this very issue.

我們生活在一個 SaaS 化的世界中。公司依賴大量 SaaS 應用程序，但這種依賴會帶來漏洞，特別是在令牌方面，即充當這些應用程序密鑰的小數據片段。受損的令牌可以讓網絡犯罪分子輕鬆訪問，甚至繞過多重身份驗證 (MFA)。最近的違規事件凸顯了這個問題。

Consider the Salesloft/Drift breach of August 2025, where attackers harvested OAuth tokens and accessed hundreds of customer organizations' data. A single unrotated API token compromised Cloudflare's Atlassian environment in November 2023, even after rotating 5,000 credentials! These incidents underscore a concerning trend: token theft is a highly effective attack vector.

考慮一下 2025 年 8 月發生的 Salesloft/Drift 洩露事件，攻擊者獲取了 OAuth 令牌並訪問了數百個客戶組織的數據。 2023 年 11 月，即使在輪換 5,000 個憑證之後，單個未輪換的 API 令牌也破壞了 Cloudflare 的 Atlassian 環境！這些事件凸顯了一個令人擔憂的趨勢：代幣盜竊是一種高效的攻擊媒介。

SaaS Sprawl: The Perfect Breeding Ground for Token Blind Spots

SaaS 蔓延：代幣盲點的完美滋生地

Why are these breaches so common? The issue lies in the uncontrolled expansion of SaaS usage, often referred to as "SaaS sprawl." Departments adopt various SaaS tools, creating a complex web of integrations and, consequently, a surge in OAuth tokens and API keys. Many of these integrations operate outside the purview of IT or traditional security solutions, creating ungoverned attack surfaces.

為什麼這些違規行為如此普遍？問題在於 SaaS 使用的不受控制的擴展，通常稱為“SaaS 蔓延”。各部門採用各種 SaaS 工具，創建複雜的集成網絡，從而導致 OAuth 令牌和 API 密鑰激增。其中許多集成在 IT 或傳統安全解決方案的範圍之外運行，從而形成不受監管的攻擊面。

This blind spot is fueled by a lack of visibility, absent approval processes, and insufficient monitoring. Employees freely connect apps without proper vetting, granting broad permissions that are rarely reviewed. Security teams often discover these connections only after a breach occurs.

缺乏可見性、缺乏審批流程和監控不足加劇了這一盲點。員工無需經過適當的審查即可自由連接應用程序，從而授予很少審查的廣泛權限。安全團隊通常只有在發生違規事件後才會發現這些連接。

Why Legacy Security Solutions Fall Short

為什麼傳統安全解決方案達不到要求

Traditional security tools like SSO and MFA, while crucial, don't fully address the token problem. OAuth tokens bypass these controls, granting persistent trust without further verification. Attackers can leverage valid tokens to access data as if they were already authenticated, with no MFA re-checks. Cloud Access Security Brokers (CASB) often focus on user-to-app traffic, overlooking app-to-app connections.

SSO 和 MFA 等傳統安全工具雖然至關重要，但並不能完全解決令牌問題。 OAuth 令牌繞過這些控制，無需進一步驗證即可授予持久信任。攻擊者可以利用有效令牌來訪問數據，就好像它們已經經過身份驗證一樣，無需 MFA 重新檢查。雲訪問安全代理 (CASB) 通常關注用戶到應用程序的流量，而忽視應用程序到應用程序的連接。

The MITRE ATT&CK Framework: A Defensive Map for SaaS

MITRE ATT&CK 框架：SaaS 的防禦地圖

The MITRE ATT&CK framework is crucial to understand. Each tactic highlights what adversaries do, and what defenders need to look for inside SaaS platforms. SaaS requires depth of visibility into users, tokens, integrations, and objects.

理解 MITRE ATT&CK 框架至關重要。每種策略都強調了對手的行為以及防御者需要在 SaaS 平台內尋找什麼。 SaaS 需要對用戶、令牌、集成和對象的深度可見性。

With SaaS, depth of visibility turns ATT&CK into a defensive map. Practitioners should watch for across each stage of the kill chain:

借助 SaaS，深度可見性將 ATT&CK 轉變為防禦地圖。從業者應該注意殺傷鏈的每個階段：

• Initial access
• Execution
• Persistence
• Privilege escalation
• Defense evasion
• Lateral movement
• Collection
• Exfiltration

The Rise of Dynamic SaaS Security Platforms

動態 SaaS 安全平台的興起

To combat these challenges, dynamic SaaS security platforms are emerging. These platforms aim to discover and secure SaaS integrations, map out third-party apps, tokens, and privileges, and restore visibility and control. Whether through automated discovery or enforced OAuth policies, the goal is to close the SaaS security gap created by unchecked tokens.

為了應對這些挑戰，動態 SaaS 安全平台不斷湧現。這些平台旨在發現和保護 SaaS 集成，規劃第三方應用程序、令牌和權限，並恢復可見性和控制。無論是通過自動發現還是強制執行 OAuth 策略，目標都是彌補由未經檢查的令牌造成的 SaaS 安全漏洞。

Ultimately, organizations must prioritize better token hygiene practices. You can't protect what you can't see, so start by identifying your tokens and SaaS integrations. Then, control and monitor them to prevent them from becoming backdoors.

最終，組織必須優先考慮更好的代幣衛生實踐。您無法保護看不到的內容，因此首先要識別您的令牌和 SaaS 集成。然後，對它們進行控制和監控，防止它們成為後門。

And there you have it! With diligence and the right tools, you can navigate the SaaS security labyrinth and keep those precious tokens safe and sound. After all, a little paranoia goes a long way in cybersecurity.

現在你就得到了它！通過勤奮和正確的工具，您可以在 SaaS 安全迷宮中導航並確保這些寶貴的代幣安全無虞。畢竟，一點偏執對網絡安全大有幫助。
