Cloud Sec Notes

Modern cloud architecture relies on a few foundational building blocks that determine how secure, scalable, and well‑organized your environment will be. Three of the most important concepts— Perimeter Security , Landing Zones , and Hub‑and‑Spoke architecture —often get mixed up or used interchangeably, even though each plays a very different role. Understanding how these pieces fit together is essential for designing a secure cloud environment that can handle real‑world workloads. This guide breaks down each concept in simple terms and uses a practical analogy to help you visualize how they work individually and as part of a unified cloud security strategy. 1. Perimeter Security in Cloud This refers to the outermost security boundary where external traffic first interacts with your cloud environment. In traditional networks, this was the firewall at the edge. In cloud, it’s often implemented using: Cloud-native firewalls (e.g., GCP Firewall Rules, AWS Security Groups/NACLs) Web Appli...

Managing security across Google Cloud, Azure, and AWS can feel overwhelming, especially as businesses adopt multi‑cloud environments and face constantly evolving threats. Each cloud provider offers its own CSPM, CWP, SIEM, and threat‑detection tools—but knowing which service does what is essential for building a strong security foundation. This guide breaks down the core security services across all three major cloud platforms, helping you compare capabilities, understand their roles, and choose the right controls to strengthen your cloud security posture.
