How does Zero Trust approach the concept of continuous authentication?

Zero trust relies on continuous authentication to validate user and device identities in real time by constantly verifying the identity and security posture of users and devices accessing the network or resources, rather than relying on a one-time authentication at the initial login. This approach involves continuously monitoring and analyzing various factors such as user behavior, device health, location, time of access, and more to ensure that access is granted based on the most up-to-date information available. This dynamic verification process helps enhance security by maintaining a continuous assessment of trust levels and adapting access permissions accordingly.
