"هندسة الثقة الصفرية: تحول جذري في الأمن السيبراني"

## Introduction In the ever-evolving landscape of cybersecurity, traditional perimeter-based defenses are proving inadequate in combating modern threats. Enter Zero Trust Architecture—an innovative approach that redefines cyber defenses by eliminating implicit trust within an organization's network and continuously verifying each connection. ## Understanding "Zero Trust Architecture Redefines Cyber Defenses" Zero Trust Architecture (ZTA) is a security model that operates on the principle of "never trust, always verify." Unlike traditional security models that assume everything inside an organization's network can be trusted, ZTA assumes that threats can be both internal and external. ### Key Concept 1: Principle of Least Privilege The principle of least privilege is a fundamental aspect of Zero Trust. This means that users, systems, and applications are granted the minimum level of access necessary to perform their functions. By minimizing access rights, the risk of unauthorized access is significantly reduced. ### Key Concept 2: Micro-Segmentation Micro-segmentation involves dividing a network into smaller, isolated segments. This approach limits lateral movement within a network, ensuring that even if a breach occurs, the attacker’s movement is restricted. Each segment acts as an independent unit with its own security controls. ### Key Concept 3: Continuous Verification Zero Trust Architecture emphasizes continuous verification of every user and device. This is achieved through real-time monitoring and analytics to detect anomalies and ensure that only authenticated and authorized users gain access to critical resources. ## Core Features and Benefits - **Enhanced Security**: By removing implicit trust, ZTA significantly reduces the attack surface. - **Improved Compliance**: Adherence to rigorous access controls helps organizations meet regulatory requirements. - **Scalability**: Zero Trust strategies can be scaled to accommodate growing and changing networks. ## T...
