Just-in-time access approval with micro-segmentation turns that principle into a system. It strips away standing privileges, shrinks attack surfaces, and grants entry only for the exact moment it’s needed. No more dormant permissions lingering for weeks. No more over-provisioned accounts waiting to be exploited. Every action is deliberate. Every session is temporary.
At its core, just-in-time access approval enforces an on-demand workflow. A user requests access. The request is checked against a security policy. If approved, permissions are deployed instantly and expire automatically. This model blocks lateral movement, reduces insider threats, and makes privilege escalation far harder.
Micro-segmentation locks it all into smaller, controlled zones. Instead of one flat network, you divide it into secure, isolated segments. Each request is tied to a specific micro-segment and role, ensuring that even if credentials are stolen, their value is minimal. Together, these two approaches cut your attack surface down to the bone.
