Packet Sniffing
Packet sniffing is a network analysis technique that involves capturing and inspecting data packets as they travel across a network. It allows developers and network administrators to monitor network traffic, diagnose issues, and analyze protocols by intercepting and logging packets in real-time. This is typically done using specialized software tools that can decode packet headers and payloads for detailed examination.
Developers should learn packet sniffing for network troubleshooting, security auditing, and protocol development, as it helps identify bottlenecks, detect malicious activity, and verify data integrity. It is essential in scenarios like debugging API calls, analyzing web traffic, or ensuring compliance with network policies, particularly in cybersecurity, DevOps, and backend development roles.
