The old adage "trust but verify" is dead. In the modern cyber threat landscape, the new mantra for Small and Medium Enterprises (SMEs) must be "never trust, always verify."
What is Zero Trust?
Zero Trust is not a single product; it's a strategic framework for security that eliminates implicit trust and continuously validates every stage of digital interaction. For an SME in Ranchi or anywhere in India, this means moving away from the idea that everyone inside the office Wi-Fi is "safe."
The Three Pillars
- Continuous Verification: Always authenticate and authorize based on all available data points, including user identity, location, device health, and service or workload.
- Limit the Blast Radius: Minimize impact in case of an external or internal breach by using micro-segmentation.
- Automated Contextual Response: Collect context and data from the entire IT stack to improve policy enforcement and response speed.
