widely adopted is Zero-Trust Security. Given the evolution of cyber threats, old-fashioned security approaches that are built on the walls of a perimeter are no longer of any help. Zero-trust security functions on the assumption that no one – in other words, an insider or outsider – is ever trusted outright.

This article explains what zero-trust security means, why it is essential in the field of software development, and how to implement it successfully. What is Zero-Trust Security? Zero-trust security treats all actors (users, devices), devices (hardware like laptops, phones), and networks as threats. Unlike Legacy Models that trust users within a network perimeter, Zero-Trust computes trust (verification) at every interaction (access request).

At its core, the Zero-Trust model emphasizes: Verification of every request : All requests for access made by users, whether internal or external, go through proper authentication and authorization processes. : All requests for access made by users, whether internal or external, go through proper authentication and authorization processes. Least privilege access : Users are provided only the necessary rights to perform their activities.

: Users are provided only the necessary rights to perform their activities. Micro-segmentation : The access to the network is broken into smaller independent sections to reduce the span of possible attacks. : The access to the network is broken into smaller independent sections to reduce the span .
