4. Zero Trust Architecture

Zero Trust security initiatives among companies reached 97% in 2022, up from just 16% in 2019 (Source: Statista). Traditional network security models have long relied on the assumption that entities within the network can be trusted once they have gained initial access. However, the increasing sophistication of cyber threats has rendered this approach insufficient. Enter Zero Trust Architecture (ZTA), a security framework that assumes zero trust for both internal and external users and devices. ZTA encompasses various components, including identity and access management (IAM), network segmentation, continuous monitoring, and advanced analytics. It treats every user, device, and network component as potentially untrusted, requiring continuous verification and authorization.

The key principle of zero-trust architecture is the concept of least privilege, where users and devices are granted only the minimum level of access required to perform their tasks. This approach significantly limits the potential impact of a compromised account or device. Implementing granular access controls and multi-factor authentication will ensure that users and devices are authenticated at each step. This minimises the risk of unauthorised access or lateral movement within the network.
