Azure Network Security Troubleshooting

When cloud applications fail to communicate, identifying the root cause within complex cloud network boundaries can be challenging. This text-only course provides a clear, structured path to diagnosing and fixing security-related network failures. You will transition from guessing why traffic is blocked to systematically isolating issues using modern cloud tools. Learn to resolve common configuration errors, analyze traffic flows, and maintain a secure environment. What you'll learn: - Understand foundational Azure networking concepts, including virtual networks, subnets, and default routing behaviors. - Diagnose Network Security Group (NSG) misconfigurations and resolve conflicting rules. - Troubleshoot Azure Firewall policies and Web Application Firewall (WAF) blocks on application gateways. - Analyze network latency and path issues using Network Watcher and Connection Monitor. - Implement modern zero-trust security principles to secure virtual network boundaries. - Interpret diagnostic flow logs and metrics to trace blocked or dropped traffic. This course begins with essential terminology and the foundational mechanics of cloud packet filtering. From there, you will progress through practical scenarios involving firewalls, security groups, and advanced diagnostic utilities. This course is designed for IT professionals, support engineers, and systems administrators who are new to cloud networking and want to build practical troubleshooting skills.
