"To stop a ghost, you must first learn to walk through walls."

Understanding evasion makes you a . When you know how attackers hide, you can build stronger detections.

Packet Fragmentation: By breaking a single malicious packet into several smaller fragments, an attacker can bypass firewalls that do not reassemble packets before inspection. The fragments pass through individually, only to be reassembled by the target host's operating system.IP Address Decoying: This involves sending packets with spoofed source IP addresses. While the firewall may block some, the sheer volume of "decoy" traffic can mask the attacker's actual IP, making it difficult for the firewall to identify the true source of the scan.Source Routing: Though less common today due to better security configurations, source routing allows an attacker to specify the exact path a packet should take through the network, potentially bypassing a firewall entirely.Tunneling (Encapsulation): This involves wrapping one protocol inside another. For example, tunneling restricted traffic over DNS or HTTP (which are usually allowed) can effectively bypass firewall rules. IDS Evasion: Staying Under the Radar

Ethical hacking involves legally testing defenses like Intrusion Detection Systems (IDS), firewalls, and honeypots to identify and fix security gaps

Honeypots are traps. They emulate vulnerable services (like an old SMB share or a SSH server) but are isolated from real data.
