What characterizes zero trust architecture?

Zero trust architecture is fundamentally characterized by the principle that all requests for access—both from outside the network and within—should be treated as potentially harmful. This approach operates under the assumption that threats could emerge from any source, whether it is an external attacker or a legitimate user whose account has been compromised.

By considering each access attempt as a potential threat, zero trust architecture enhances security by necessitating verification at every stage of access. This often includes strong authentication measures, continuous monitoring, and strict policies governing access rights, rather than relying on perimeter defenses to safeguard sensitive data.

The notion that all internal and external requests could pose threats aligns directly with the philosophy of "never trust, always verify," which is central to zero trust. This proactive stance significantly reduces the risk of breaches that may be facilitated by overly trusting any user or device, thereby bolstering an organization’s overall security posture.

In contrast, relying solely on user passwords does not encapsulate the broader verification strategies used in zero trust frameworks, which demand multiple forms of authentication. Limiting access to only high-ranking employees does not address the broader risk management strategy that applies equally across all user levels and roles. Similarly, operating under the belief that the network is always secure contradicts the zero trust
