Session 2 – Zscaler – Zero Trust

Zero trust is a security model in which access to network resources is based on the principle of least privilege. Under a zero trust model, every network access request is treated as if it is coming from an untrusted source, regardless of the source’s location or previous access history. This means that even traffic coming from inside the network is subject to the same strict security controls as traffic coming from outside the network. The goal of zero trust is to reduce the attack surface and limit the impact of a successful breach by assuming that the network is already compromised, and then implementing security controls to prevent attackers from moving laterally and accessing sensitive resources.

Zero trust is an approach to designing security architectures based on the premise that every interaction begins in an untrusted state. This contrasts with traditional architectures which may determine trustworthiness based on whether communication starts inside a firewall.
