Cybersecurity Fundamentals : Cloud, Zero Trust, and You Chapter 5
Description
Cloud perimeters are fading, identities are multiplying, and threats move faster than patches. We dive into the real mechanics of securing a hybrid world—mapping cloud deployment choices, clarifying shared responsibility across SaaS, PaaS, and IaaS, and showing how Zero Trust reshapes defenses around identity, posture, and context. It’s a practical tour from first principles to field-tested patterns, grounded by case studies like Capital One and SolarWinds and anchored in frameworks such as NIST SP 800-207.
We start by decoding public, private, hosted private, community, and hybrid models, then connect those choices to risk: multi-tenant isolation, data flows between zones, and the observability challenges of decentralization. From there, we move into reliability engineering—high availability, geo-redundancy, disaster recovery—and the role Kubernetes plays in scaling securely, with a frank look at container pitfalls and how least privilege and image scanning reduce blast radius. Automation takes center stage with infrastructure as code, autoscaling, and software-defined networking, plus how SASE brings secure access to a remote-first workforce without bolting on more complexity.
Embedded systems and IoT get a hard look: scarce memory, weak encryption, default credentials, and unpatchable firmware that turns convenience into risk. We offer a simple playbook—segment aggressively, enforce egress controls, rotate credentials, and plan device lifecycles—to stop small sensors from causing big outages. Zero Trust ties it all together: never trust, always verify; microsegment to prevent lateral movement; and evaluate every access request through identity, device health, and real-time signals. Along the way, we weave in Security+ exam-style questions so you can test your knowledge and lock in the fundamentals.
