CYBERSECURITY EXPLAINED
Zero-trust microsegmentation: limiting the blast radius
Detection matters. Containment determines how far an incident can travel.Why does microsegmentation matter in zero trust?
Microsegmentation separates systems and workloads into smaller policy-controlled zones. If an identity or device is compromised, separation can make lateral movement harder and reduce potential damage.
Assume breach instead of trusting the internal network.
Apply least privilege between workloads, identities and zones.
Measure operational complexity alongside security benefit.
01
From perimeter to policy
Traditional perimeter security can fail when attackers obtain valid credentials or enter through trusted systems. Zero trust evaluates access continuously.
02
Containment is an outcome
The goal is to stop one compromised point from reaching everything else.
03
Implementation risk
Poorly designed segmentation can disrupt operations. Discovery, testing, observability and phased policy are critical.
