available TCP and UDP ports on any given machine, acting as communication endpoints for applications. Common Scanning Techniques 🛡️ Mastering Network Defense: Intro to Port Scanning

Instead of hitting thousands of ports in a few seconds, advanced scans are spaced out over hours or days. This slips right past simple threshold alarms. Scans like "Xmas" (setting FIN, PSH, and URG

Scans like "Xmas" (setting FIN, PSH, and URG flags) or "Null" scans (no flags set at all) manipulate the TCP state machine to see how the OS responds, mapping out the architecture without leaving heavy footprints. 🚨 Part 3: How Snort Defends Your Network Scans like "Xmas" (setting FIN

By mastering how these scans operate and how to detect them using industry-standard tools like Snort , security teams can slam the door on attackers before they ever find a way in. 🚪 Part 1: The Basics of Network Port Scanning
