Port Scanning And Advanced Techniques: How Snort | Intro To Network

Snort is the world's most widely deployed open-source Network Intrusion Detection and Prevention System (NIDS/NIPS). It analyzes traffic in real time and compares it against predefined rules or behavioral thresholds. Snort - Network Intrusion Detection & Prevention System

In cybersecurity, it is often the very first phase of an attack—reconnaissance. Snort is the world's most widely deployed open-source

At its core, a port scan probes a server or host to see which ports are "listening" (open) and what services are running. There are At its core, a port scan probes a

🕵️‍♂️ Part 2: Advanced Port Scanning & Evasion Techniques Instead of hitting thousands of ports in a

Sophisticated attackers don't just use loud, default scans. They leverage evasive maneuvers to bypass traditional firewalls and Intrusion Detection Systems (IDS).

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.

The attacker spoofs active IP addresses along with their real IP, creating a flood of fake scans that mask the true origin.
