Security is the most critical aspect for any IT solutions and with the ever-increasing adoption of cloud-native technologies, the need for Zero Trust Architecture is irrefutable as:
- The traditional networking approach is not effective enough to provide full security to cloud-native applications.
- With cloud offerings being heavily getting used going forward, security policies around the application need to be scalable as well.
- With more emphasis on loosely coupled microservice-based applications, chances of vulnerabilities getting introduced also increases.
- People are using multiple clouds to take advantage of the offerings.
- On-premise to the cloud and another way around connectivity is a reality.
- Devices that span beyond traditional data centres & cloud are increasingly being used to provide connectivity to remote sites.
To sum up, it means there is no "real network boundary" anymore, and hence we need to have a way in which we don't trust anyone. Traditionally it was assumed that communication between entities inside the same data centre is secure; whereas with zero trusts, we don't even assume that. So, it has become a mandate to have a zero-trust security framework around your cloud-native applications.
