Lab 08: Secure & Audit Cloud Network Access with Security Groups + VPC Flow Logs

In this lab, we secure network access using Security Group rules, test allowed vs. blocked traffic, then enable VPC Flow Logs and analyze accepted/rejected traffic using CloudWatch for a complete audit trail. 🔹 What you'll learn: Configuring security group rules for controlled network access Testing allowed and blocked traffic against those rules Enabling VPC Flow Logs on your VPC/subnet/network interface Sending flow log data to CloudWatch Logs Analyzing accepted vs. rejected traffic for auditing and troubleshooting This is Lab 08 in the Cloud Networking Lab Series, covering practical security and observability concepts across AWS, Azure, and GCP. 📌 Previous labs: Lab 01 – Design a Virtual Network with Public & Private Subnets Lab 02 – Routing & NAT for Controlled Internet Access Lab 03 – Private DNS in AWS: Custom Hostname to EC2 Private IP Lab 04 – Network-Level Security Controls with AWS Security Groups Lab 07 – Deploy a Scalable, Highly Available Web App with Load Balancing ⏱️ Timestamps: 0:00 Introduction (add your own once edited) #AWS #VPCFlowLogs #CloudWatch #CloudSecurity #NetworkAudit #CloudComputing #AWSTutorial
