Zero Trust Networks: Building Secure Systems in Untrusted Networks

Zero Trust Networks: Building Secure Systems in Untrusted Networks"Perimeter defences guarding your network arent as secure as you might think. Hosts behind the firewall have no defences of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. This practical book introduces you to the zero trust model, a method that treats all hosts as if theyre internet facing and considers the entire network to be compromised and hostile. Authors Evan Gilman and Doug Barth show

"Perimeter defences guarding your network arent as secure as you might think. Hosts behind the firewall have no defences of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. This practical book introduces you to the zero trust model, a method that treats all hosts as if theyre internet-facing and considers the entire network to be compromised and hostile.Authors Evan Gilman and Doug Barth show you how zero trust lets you focus on building strong authentication, authorization and encryption throughout, while providing compartmentalized access and better operational agility. Youll learn the architecture of a zero trust network, including how to build one using currently available technology.Understand how the zero trust model embeds security within the systems operation, rather than layering it on topExamine the fundamental concepts at play in a zero trust network, including network agents and trust enginesUse existing technology to establish trust among the actors in a networkLearn how to migrate from a perimeter-based network to a zero trust network in productionExplore case studies of zero trust on the client side (Google) and on the server (PagerDuty)
