Why Does Zero-Trust Security Assume No User or Device Is Safe?
Discover the foundational principles of zero-trust security. Learn why modern networks use the “never trust, always verify” model to constantly authenticate users and protect against internal and external threats.
Question
What is the foundational principle of zero-trust security?
A. Grant broad access to all authenticated users.
B. Trust all users and devices within the network perimeter.
C. Rely primarily on strong perimeter defenses.
D. Assume no user, device, or system is inherently trusted, even inside the network.
Answer
D. Assume no user, device, or system is inherently trusted, even inside the network.
Explanation
The zero-trust security model completely abandons the old idea that everything inside a company’s network is safe. Instead, it operates on a strict “never trust, always verify” rule. Whether an access request comes from an employee sitting in the main office or a remote worker logging in from a coffee shop, the system treats every connection as a potential threat. Every user and device must continuously prove their identity and authorization before they are allowed to access any data or applications.
