Organizations that steadfastly relied on the “flat network” approach of firewalls and VPNs to regulate access now find themselves lacking the visibility, solution integration, and agility needed to deliver end-to-end security. A new model needed to adapt to a remote workforce, protecting people, devices, applications, and data—from anywhere.
In a Zero Trust security model, every access request is strongly inspected for anomalies before granting access. Everything from the user’s identity to the application’s hosting environment is authenticated and authorized using micro-segmentation and least privileged-access principles to minimize lateral movement.
Zero Trust means adhering to three cohesive principles:
Verify explicitly: Always authenticate and authorize based on all available data points, including—user identity, location, device health, service or workload, data classification, and anomalies.
Use least privileged access: Limit user access with just-in-time (JIT) and just-enough-access (JEA), risk-based adaptive polices, and data protection to help secure both data and productivity.
Assume breach: Minimize the blast radius and prevent lateral movement by segmenting access by network, user, devices, and app awareness. Verify all sessions are encrypted and use analytics to gain visibility, drive threat detection, and improve defenses.
