什麼是安全服務邊緣 (SSE)？

How Does SSE Work?

SSE works to protect data, detect threats, and control environment access. It integrates with existing security and cloud services, using cloud-native technologies to offer real-time visibility and control over user activities and data flows.

• Data Protection: SSE employs advanced security mechanisms like encryption, data loss prevention (DLP), and secure access controls to safeguard sensitive information both in transit and at rest.
• Threat Detection: SSE enables rapid response to incidents through use of real-time threat detection, powered by machine learning and artificial intelligence (AI), to identify anomalies and potential threats.
• Access Control: SSE enforces granular access controls based on user identity, device posture, and contextual factors, using a zero trust approach to minimize the attack surface.

The cloud-native technologies that SSE uses allow for scalability, provide consistent protection across various environments, and offer the flexibility to adapt.

安全服務邊緣的主要組成部分是什麼？

安全服務邊緣 旨在將網路安全整合到一個基於雲端的解決方案中。SSE 的主要組件包括：

• 零信任網路存取 (ZTNA): ZTNA 提供了虛擬私人網路 (VPN) 的卓越替代方案，可安全地遠端存取公司資源。ZTNA 使組織能夠實施精細的應用程式內零信任安全，以遠端存取駐留在本地或雲端的企業應用程式（例如內部 Web 應用程式、wiki、資料庫、遠端桌面和伺服器、SSH 終端和雲端生產環境）。
• 安全 Web 閘道器（SWG）: SWG 旨在保護員工免受網路和基於 Web 的威脅，包括網路釣魚網站、惡意軟體和勒索軟體感染點以及命令和控制 (C2) 機器人用戶端。SWG 監控和過濾網絡流量，以強制執行公司安全性原則，阻止對已知不正確的網站的存取，以及阻止惡意檔案到達使用者的系統。 SWG的關鍵功能是存取控制、資料保護和威脅防護。
• 防火牆即服務 (FWaaS): 防火牆是企業網路安全策略的基石，使組織能夠限制網路存取並阻止惡意檔案進入網路。FWaaS 產品在基於服務的模型下提供防火牆功能，比基於設備的解決方案提供更大的靈活性和可擴展性。在 SSE 中，FWaaS 是指使用基於雲端的網路安全性來保護分公司、資料中心和遠端站點的安全性。FWaaS 與軟體定義廣域網路解決方案集成，以自動化方式在眾多站點和分支機構之間實施一致的安全性。
• 雲端存取安全代理（CASB）: 隨著公司越來越依賴一系列軟體即服務 (SaaS) 應用程序，他們需要能夠跨雲端服務實施公司安全策略和存取控制的解決方案。CASB 解決方案可協助管理存取並保護軟體即服務應用程式中存取的數據，其功能包括身份驗證、單一登入、授權、加密、監控和威脅防護等。
• Identity and Access Management (IAM): IAM governs user identities and access to resources, enabling organizations to manage user identities, enforce authentication protocols, and implement role-based access controls.
• Data Loss Prevention: DLP mechanisms protect sensitive information from unauthorized access and exfiltration, monitoring data in motion, at rest, and in use, and applying policies to prevent data leaks.

SSE vs. SASE: What’s The Difference?

While both SSE and SASE aim to secure cloud environments and remote workforces, they serve distinct purposes.

莎士

莎士 primarily focuses on delivering essential security services, such as:

• Data protection
• Threat detection
• 存取權限管控

SSE does not address networking aspects. It prioritizes security-first strategies, making it well-suited for organizations handling sensitive data or that otherwise require advanced data protection and threat detection capabilities, facilitating regulatory compliance.

SASE

SASE combines the security services from SSE with:

• Wide-area networking (WAN) capabilities
• Zero Trust Network Access (ZTNA) principles

This provides a comprehensive solution for secure access to applications and data. SASE offers similar capabilities, it is ideally suited for organizations with a distributed workforce accessing cloud applications.

It optimizes both security and network performance, ensuring seamless connectivity and protection.

選擇哪一個？

SSE focuses on security services, while SASE integrates security and networking. Each framework caters to different organizational needs and use cases:

• Security Service Edge: Ideal for organizations seeking to secure access to cloud resources and SaaS applications, and to implement a zero-trust approach for cloud-based assets.
• Secure Access Service Edge: Intended for organizations that require secure access to both cloud resources and on-premises networks. SASE is optimized for network performance, such as low-latency connectivity for real-time applications.

Benefits of Security Service Edge

Implementing Security Service Edge (SSE) offers advantages that enhance an organization’s security posture while addressing the challenges of cloud environments.

• Enhanced Visibility: SSE provides improved visibility into user activities and data flows across cloud environments, enabling organizations to identify potential security risks and enforce security policies.
• Improved Threat Detection: SSE solutions leverage real-time analytics and machine learning algorithms to enhance threat detection capabilities, allowing security teams to rapidly respond to threats and mitigate risks before they escalate.
• Cost-Effectiveness and Scalability: SSE solutions are often more cost-effective than traditional security measures, reducing costs. They also offer scalability, allowing organizations to easily accommodate increased user loads and changing security requirements without extensive infrastructure changes.

The enhanced visibility, control, threat detection capabilities, and scalability of SSE make it an attractive option for organizations seeking to strengthen their security.

SSE and Cyber Threats

SSE provides a framework for combating evolving cyber threats, particularly effective in mitigating threats, such as:

• 勒索
• 網路釣魚攻擊

It implements strict access controls and data protection measures, and employs advanced threat detection mechanisms to identify and block malicious links and attachments.

Machine Learning and AI

Machine learning and AI are central to enhancing threat intelligence within SSE.

These technologies enable SSE solutions to analyze vast amounts of data in real-time, identifying patterns and anomalies that may indicate potential threats. This approach allows for faster threat detection and response.

Continuous Monitoring & Adaptive Security

SSE incorporates continuous monitoring and adaptive security measures. This enables organizations to maintain real-time visibility into their security posture, quickly identify and respond to potential threats, and adjust their security policies and controls based on the ever-changing threat environment.

These capabilities position SSE as a critical component in the ongoing fight against evolving cyber threats.

3 Best Practices

Implementing Security Service Edge effectively requires adherence to best practices that enhance security and ensure the solution aligns with organizational goals.

1. Zero Trust Architecture: Adopting a zero trust architecture is fundamental to the success of SSE. This approach requires continuous authentication and authorization for every access request, ensuring that users have the minimum necessary permissions to perform their tasks.
2. Regular Security Assessments: Conduct regular security assessments to evaluate the effectiveness of the SSE implementation and identify vulnerabilities. Regular updates to SSE configurations are essential to adapt to evolving threats and changing business needs.
3. User Education Programs: Implement comprehensive user education and awareness programs to inform employees about security best practices and the importance of adhering to security policies. Regular training sessions and updates can help reinforce these concepts and keep security top of mind for all employees.

Effective adoption of these best practices enables organizations to significantly bolster their security posture, ultimately ensuring that the implementation is highly effective at mitigating risks.
