What is zero trust security in simple words?

Zero Trust Security is a cybersecurity strategy that operates on the fundamental principle of “trust no one.” In straightforward terms, it means never assuming implicit trust for any user, device, or system within a network. Instead, every interaction and access request is rigorously authenticated and authorized, irrespective of the entity’s location or previous network access.
This approach enhances security by consistently verifying identities and permissions, assuming potential threats can originate both externally and internally.
Essentially, Zero Trust Security minimizes the risk of unauthorized access and data breaches by adopting a continuous and meticulous validation process for all network activities.
