شبكات الثقة الصفرية: عصر جديد للأمان الرقمي

## Introduction In an era where cyber threats are becoming increasingly sophisticated, traditional security models are proving inadequate. This has led to the rise of Zero-Trust Networks, a paradigm shift that is redefining the frontiers of cybersecurity. **Zero-Trust Networks** operate on the principle of "never trust, always verify," ensuring that no entity is trusted by default, whether inside or outside the network. ## Understanding Zero-Trust Networks Redefine Security Frontiers The Zero-Trust model breaks away from the conventional approach of securing the network perimeter, focusing instead on securing individual resources. ### Key Concept 1: Micro-Segmentation Micro-segmentation involves dividing the network into smaller, isolated segments. This limits the potential spread of an attack, allowing for more granular security controls. ### Key Concept 2: Identity Verification In Zero-Trust Networks, identity verification is paramount. Every user and device must be authenticated and authorized before accessing resources, using multi-factor authentication (MFA) and other identity management techniques. ### Key Concept 3: Least Privilege Access This principle ensures that users have minimal access rights needed to perform their tasks, reducing the risk of an insider threat or lateral movement within the network. ## Core Features and Benefits - **Enhanced Security**: By not trusting any entity by default, the risk of unauthorized access is minimized. - **Reduced Attack Surface**: Micro-segmentation and least privilege access significantly reduce the potential entry points for attackers. - **Improved Compliance**: Aligns with regulatory requirements by enforcing strict access controls and comprehensive monitoring. ## Technical Deep Dive ### Architecture/Technology Zero-Trust Networks rely on a combination of technologies including software-defined perimeters, data encryption, and continuous monitoring systems. These technologies work together to enforce a stringent s...
