Define the concept of “Zero Trust” in Fortinet’s security approach.

The concept of "Zero Trust" in Fortinet’s security approach emphasizes that no implicit trust should be assumed for any user or device, regardless of whether they are inside or outside the network perimeter. This means that every access request is treated with skepticism, and users must continuously authenticate and validate their identity before being granted access to resources.

In a Zero Trust model, security controls are applied consistently across the entire environment, and strict policies govern how and when users and devices can gain access to sensitive data and applications. This approach helps mitigate risks associated with insider threats and potential vulnerabilities that can be exploited by external attackers. By not automatically trusting any user or device, organizations can better safeguard their assets and ensure a higher level of security.

Other options such as assuming all users are trusted do not align with the principles of Zero Trust, which fundamentally rejects the notion of implicit trust. Similarly, focusing solely on physical network security or centralizing all security policies does not constitute the core tenets of the Zero Trust framework, which is about continuously verifying each access request on an individual basis.
