"Zero trust" security is a cybersecurity model that operates on the principle of never trusting any user or system, regardless of their location, and always verifying identity and access privileges before granting access to resources. It emphasizes a strict acceptance policy, assuming potential breaches can originate from both internal and external sources. Utilizing technologies such as multi-factor authentication and micro-segmentation, this approach minimizes risks and protects sensitive data more effectively. By continuously monitoring user behavior, zero trust enhances overall network security and strengthens an organization's response to threats.
