هندسة الثقة الصفرية: ثورة في الدفاع السيبراني

## Introduction In today's digital landscape, traditional cybersecurity measures are proving inadequate against sophisticated cyber threats. Enter **Zero Trust Architecture (ZTA)**, a revolutionary approach that is redefining cyber defense strategies. ## Understanding "Zero Trust Architecture Redefines Cyber Defense" ### Key Concept 1: What is Zero Trust? Zero Trust is a security framework centered on the philosophy that organizations should 'never trust, always verify.' Unlike traditional models, Zero Trust assumes that threats are omnipresent, and thus, verification is necessary for every transaction. ### Key Concept 2: The Shift from Perimeter-Based to Identity-Centric Security Traditional cybersecurity relied on building robust perimeters to keep threats out. However, with the rise of cloud computing and remote work, these perimeters have dissolved. Zero Trust shifts the focus to identity and access management (IAM), ensuring that only authenticated and authorized users can access resources. ### Key Concept 3: Microsegmentation and Least Privilege Principles Zero Trust employs microsegmentation and least privilege principles to minimize the attack surface. By dividing networks into smaller, secure zones and granting minimal access rights, ZTA reduces the potential damage from breaches. ## Core Features and Benefits - **Identity Verification**: Continuously authenticates user identities and access requests. - **Granular Access Controls**: Implements precise controls over who can access specific resources. - **Enhanced Visibility**: Provides comprehensive monitoring of network activity and user behavior. - **Reduced Attack Surface**: Limits exposure by using microsegmentation and least privilege access. ## Technical Deep Dive ### Architecture/Technology Zero Trust Architecture integrates various technologies such as IAM, firewall, and security information and event management (SIEM) systems to create a unified security posture. ### Implementation Details Implement...
