نماذج الثقة الصفرية تعيد صياغة الدفاع السيبراني

## Introduction In an era where data breaches and cyberattacks are increasingly sophisticated, the **Zero-Trust Model** offers a fresh paradigm in cybersecurity. By redefining traditional defense mechanisms, this model shifts the focus from perimeter security to a more granular, identity-based approach. ## Understanding "Zero-Trust Models Redefine Cyber Defense" ### Key Concept 1: The Principle of "Never Trust, Always Verify" The Zero-Trust Model is built on the foundational principle of "never trust, always verify." Unlike traditional models that assume everything inside a network is safe, zero trust requires verification of every request as though it originated from an open network. ### Key Concept 2: Micro-Segmentation Micro-segmentation involves dividing a network into distinct security segments, down to the individual workload level. This allows for more precise control over traffic, minimizing the potential impact of a breach. ### Key Concept 3: Identity and Access Management (IAM) Identity and Access Management is integral to the Zero-Trust Model. It ensures that only authenticated and authorized users and devices can access specific resources, thereby reducing the attack surface. ## Core Features and Benefits - **Enhanced Security**: By verifying every access request, the model reduces the risk of unauthorized access. - **Minimized Risk**: Micro-segmentation limits the potential damage of a breach to a single segment. - **Increased Visibility**: Constant monitoring and logging of traffic provide better insight into network activity. ## Technical Deep Dive ### Architecture/Technology The architecture of a Zero-Trust Model typically includes components like a **secure access broker**, **strong encryption methods**, and **multi-factor authentication**. These elements work in concert to ensure that all network traffic is secure. ### Implementation Details Implementing a Zero-Trust Model requires a shift in mindset and technology. Organizations must adopt an iden...
