Zero-trust networks are often deemed compromised and untrusted, making authentication variables essential to security. Expert Matthew Pascucci explains a zero-trust security model.
In the past, we’ve done a great job of making networks accessible. But with this increased availability, we’ve opened the door for attackers to move more easily around networks.
However, as we introduce mobility and cloud solutions, our networks are evolving and perimeters are dissolving. With that being said, we are still building networks on a rigid, zone-based model, and the assumption is still being made that systems on the internal LAN are safer than external systems. This assumption has us applying different levels of trust based on the physical or logical location of systems; historically, this has been proven not to work in the long term.
Today, we continue to use choke points, filtering devices and network gear to funnel traffic between these zones, but this isn’t always efficient, secure or scalable when additional zones are needed. Segmentation is a basic tenet of information security, and using a zero-trust model shifts the mindset of where to segment and how to apply policies to endpoints.
