Zero Trust Security: Identity-First Architecture for Cloud-Native Applications

What if the network perimeter you spent years building has already become the attacker's highway? In cloud-native environments, containers migrate across hosts, serverless functions exist for milliseconds, and APIs communicate across organizational boundaries. The castle walls of traditional security-firewalls, VLANs, and private subnets-no longer protect what matters. An S3 misconfiguration, a cached CI credential, or a compromised developer laptop can bypass every network control you have architected. This book ... Read More

What if the network perimeter you spent years building has already become the attacker's highway? In cloud-native environments, containers migrate across hosts, serverless functions exist for milliseconds, and APIs communicate across organizational boundaries. The castle walls of traditional security-firewalls, VLANs, and private subnets-no longer protect what matters. An S3 misconfiguration, a cached CI credential, or a compromised developer laptop can bypass every network control you have architected. This book bridges the gap between Zero Trust philosophy and production-grade implementation. Written from the trenches by a cloud security architect who has responded to breaches at 3 AM, it treats Zero Trust not as a product category, but as an engineering discipline. Inside, you will learn: - Why most "Zero Trust" rollouts are merely security theater-and how to spot the gaps before attackers do - How identity becomes your true perimeter when workloads are ephemeral and boundaries dissolve - The architectural patterns that make SPIFFE identities, OPA policies, and mTLS meshes work as a unified system - Why continuous verification beats one-time authentication when protecting financial transactions, healthcare data, and critical infrastructure For platform engineers, security architects, and DevSecOps teams, this is the systematic framework you need to build resilient systems where compromise is assumed, authorization is granular, and verification never stops. The perimeter is dead. Architect what comes next-get your copy today. Read Less
