The Customer Network zone includes the various use-cases listed above – namely, corporate offices, third-party suppliers, and end-users working from everywhere. We agree with the SASE model that access should be delivered using a smart edge, and our AT&T team has been innovating heavily in this area. This includes solutions that use virtualization and software-defined networking (SDN) to enhance the evolving edge.
The Access Network and AT&T Network zones are embedded into our service infrastructure. You can think of these components as being the means by which we extend our massive network from a common internal core to broad geographic coverage for our global customer base. This is true for both wireless communications using 4G and 5G technology and for our world-class fiber infrastructure serving broadband connectivity to customers.
The Edge Locations and Cloud Interconnect zones support the device-to-cloud needs of our customers. Increasingly, businesses are moving from traditional physical data centers to a cloud-based architecture, where applications and workloads are the primary tools used to accomplish the organizational mission. AT&T has been at the forefront of connecting users to cloud since the invention of these capabilities.
My advice is that you start thinking about this new, evolving model as a mash-up of both zero trust and SASE – but in the context of practical network deployment and support. Experts in AT&T Labs and across our Chief Security Office are hard at work developing the model for both business and government. When supporting government, in particular, we’ve been able to draw on deep underlying capabilities developed to support that sector.
Watch this column in the coming months for more information on how you may be able to deploy these solutions in conjunction with your AT&T services. As always, we remain committed to the security and privacy of your infrastructure.
