Why Zero Trust with AT&T Cybersecurity?

The foundation of a Zero Trust Architecture

As data spreads across multiple locations, cloud vendors, and a variety of endpoint devices, traditional security that has relied on protecting organizations from the perimeter and trusting devices inside the network has become less effective. An organization’s network architecture should evolve to a Zero Trust model to align with this absence of a true perimeter.

New business initiatives and processes have created broader attack surfaces. Applications, users, and devices are moving outside of the traditional corporate zone of control, dissolving what was once the trusted perimeter, and enterprise security and networks must evolve to help protect the business.

Zero Trust objectives

Zero Trust means different things to different people, but a strategic approach to Zero Trust will first identify what it is that you’re trying to protect: the data. The ultimate goal with Zero Trust is to stop data breaches. Once the data is identified, classified and traffic flows have been enumerated, you can start to see how the access policy fits together. Many organizations have certain aspects of Zero Trust already in place, and by breaking down the organization’s security environment into 6 main pillars, you can begin to see what you can currently utilize in support of Zero Trust and what needs to be supplemented with other tools and techniques.

Zero Trust implementations

The general concept of Zero Trust applied with the above tenets serves as guidance in developing a Zero Trust Architecture (ZTA). The ZTA involves not only implemented and interconnected tools and advanced technologies, but also a set of operational policies and authentication requirements that enforce the Zero Trust principles. A ZTA can be implemented in various ways depending on an organization’s use case, business flows and risk profile. While each approach applies different components and technologies, such as enhanced identity, micro-segmentation and software defined perimeters, any approach should implement all the above tenets.
