| Titre | What Is Zero Trust? |
| Texte | Zero Trust Security Model Definition With the adoption of cloud computing, mobile devices, and the Internet of Things (IoT), the traditional network perimeter no longer exists. This has created challenges for security professionals, requiring a new approach to cybersecurity. Zero Trust has emerged as a transformative security model. Let’s take a closer look into what Zero Trust is, how it works, and the benefits it offers to modern enterprises. Zero Trust Explained Gone are the days when organizations could secure their assets with firewalls and virtual private networks (VPNs) alone. Workloads now live in the cloud, users and devices are increasingly mobile, and data flows across diverse locations and applications. This shift has widened visibility gaps and exposed vulnerabilities in legacy security approaches. Traditional security models operate on implicit trust: once a user or device gains access to the network, they’re often granted broad permissions. However, this trust can be exploited by attackers, leading to data breaches and ransomware attacks. Zero Trust flips this model on its head, assuming that no user, device, or application can be trusted by default. At its core, Zero Trust is a cybersecurity philosophy and framework designed to eliminate the assumption of trust. Instead of granting blanket access based on network location or device, Zero Trust requires: 1. Rigorous Verification: Every access request is authenticated, authorized, and continuously validated. 2. Least-Privilege Access: Users, devices, and applications are given only the permissions they need—nothing more. 3. Microsegmentation: The network is divided into granular zones to minimize potential damage in case of a breach. Zero Trust isn’t a single technology but a holistic approach that relies on solutions like identity management, secure remote access, data loss prevention, and microsegmentation to create a resilient security posture. Traditional security models grant users access to the entire network, creating opportunities for lateral movement by attackers. Zero Trust redefines access by connecting users directly to the specific applications and resources they need, bypassing the network entirely. Why It Matters: Decoupling application access from network access prevents malware from spreading and ensures users can only interact with authorized resources. o Example: Instead of relying on VPNs, Zero Trust leverages secure access solutions that enforce policies based on user identity, device posture, and real-time context. Legacy firewalls and VPNs inadvertently expose applications by making them accessible through public-facing IP addresses. Zero Trust eliminates this vulnerability by concealing applications from unauthorized users. Why It Matters: Hiding application and network resources reduces the attack surface. o Example: By obfuscating internet protocol (IP) addresses and source identities, Zero Trust prevents distributed denial-of-service (DDoS) attacks and other internet-based threats. Zero Trust uses a proxy-based approach to inspect and secure traffic between users and applications. Unlike traditional passthrough firewalls, proxies provide in-depth analysis and threat detection. Why It Matters: Proxies enable granular control and visibility, ensuring secure interactions without compromising performance. o Example: A proxy can inspect encrypted traffic for malware or unauthorized data transfers, adding an extra layer of protection. Zero Trust continuously evaluates access requests based on dynamic factors such as user identity, device health, and geolocation. Access policies are enforced throughout the session, ensuring that any changes in context trigge |
