What is Zero Trust?
The term zero trust refers to a cybersecurity approach that challenges the "traditional", perimetric security model. It is based on the principle of never trust, always verify, requiring verification and authorization for every user, device, and application attempting to perform a transaction, regardless of their location or prior authentication. This proactive strategy reduces an organization's attack surface, spanning from on-premises to cloud environments, and constrains potential breaches and latteral movement.
Zero Trust is not one single piece of technology but a combination of several principles and technologies, such as identity access management (IAM) and strong identity verification, continuous monitoring and validation of
connections, device security and compliance checks, mutual and multi-factor authentication, microsegmentation for breaches containment and latteral movement prevention, least privilege access and attribute-based access control (ABAC),
setting access policies based on the attributes of the data, user identity and environmental information, and several more.
Remember that the transformation of your cybersecurity architecture, from perimeter-based to zero trust, will not be a single project but an iterative process, incorporating several smaller projects, each one dealing with a specifc use case.
