نماذج الثقة الصفرية تعيد تشكيل الدفاع السيبراني

## Introduction In today's rapidly evolving digital landscape, traditional security models are proving inadequate. The Zero Trust Model is emerging as a revolutionary approach that redefines cyber defense strategies. It challenges the conventional 'trust but verify' paradigm by advocating 'never trust, always verify'. This article delves into the intricacies of Zero Trust and its growing significance in cybersecurity. ## Understanding "Zero Trust Models Redefine Cyber Defense" ### Key Concept 1: The Principle of Least Privilege Zero Trust operates on the principle of least privilege, where users have the minimal level of access necessary to perform their roles. This approach minimizes the risk of internal threats and lateral movement within a network. ### Key Concept 2: Micro-Segmentation Micro-segmentation involves dividing a network into smaller, isolated segments to reduce the attack surface. It ensures that even if an attacker gains access to one segment, they cannot easily move to others. ### Key Concept 3: Continuous Monitoring and Validation Unlike traditional security models, Zero Trust continuously monitors and validates user identities and device integrity throughout the access session. This ensures that any anomalies or deviations are promptly detected and addressed. ## Core Features and Benefits - **Enhanced Security**: By implementing a 'trust no one' policy, organizations significantly reduce the likelihood of breaches. - **Reduced Attack Surface**: With micro-segmentation, the scope for attackers is limited, containing potential threats effectively. - **Improved Compliance**: Zero Trust aligns with regulatory requirements, ensuring data protection and privacy laws are adhered to. ## Technical Deep Dive ### Architecture/Technology Zero Trust architectures are built on advanced technologies such as multi-factor authentication (MFA), identity and access management (IAM), and encryption. These components work in tandem to create a robust security framewor...
