 If you’re confused about Security Groups vs NACLs vs Firewalls , this guide breaks it down in plain English with the real patterns engineers actually use —how each layer works, where it applies (instance/ENI vs subnet vs perimeter), common mistakes to avoid, and practical “when to use what” examples for AWS and modern cloud architectures. Network Security made simple: ✅ Security Groups = stateful, instance/ENI-level allow rules (your primary workload guardrail) ✅ NACLs = stateless, subnet-level allow/deny rules (coarse subnet boundaries & special controls) ✅ Firewalls = centralized inspection/policy (egress control, segmentation, advanced filtering) Read the full article here: https://www.cloudopsnow.in/network-security-made-simple-security-groups-vs-nacls-vs-firewalls-and-the-patterns-engineers-actually-use/ #NetworkSecurity #AWS #CloudSecurity #SecurityGroups #NACL #Firewall #DevOps #SRE #Kubernetes #ZeroTrust #CloudOps

 If you’re building on AWS/Azure/GCP and still relying on “VPN + perimeter” thinking, this guide shows how to implement Zero Trust for Cloud the right way— identity-first , step-by-step, with real examples you can apply to users, workloads, APIs, and admin access. Zero Trust in cloud is simple in principle: never trust, always verify —every request, every time. ✅ Step 1: Identity becomes the perimeter (SSO, MFA, conditional access) ✅ Step 2: Least privilege by default (tight roles, scoped permissions, break-glass) ✅ Step 3: Secure service-to-service access (workload identity, short-lived tokens, mTLS) ✅ Step 4: Protect secrets & credentials (vault/KMS, rotation, no hardcoding) ✅ Step 5: Continuous verification (logs, detections, alerts, policy-as-code) ✅ Step 6: Assume breach (segment, limit blast radius, monitor everything) Read the full step-by-step guide here: https://www.cloudopsnow.in/zero-trust-for-cloud-identity-first-security-in-practice-step-by-step-real-example...
