Understanding evasion techniques allows security teams to improve their defensive posture.

Firewalls and IDS systems act as the frontline defense. Penetration testers often use evasion techniques to see if their malicious packets can pass unnoticed. Techniques for Firewall Evasion Techniques for Firewall Evasion Attackers scan for open

Attackers scan for open ports. To evade detection, they may use techniques like "slow scanning" (sending packets slowly over a long time) or "fin scans" to avoid triggering firewall alerts 0.5.3. Without deep packet inspection (DPI), many IDS systems

LinkedIn Ethical Hacking: Evading IDS, Firewalls, and Honeypots Without deep packet inspection (DPI)

: Sending data through SSL/TLS tunnels. Without deep packet inspection (DPI), many IDS systems cannot see the encrypted malicious content. 2. Evading Network & Web Application Firewalls (WAF)

Firewalls inspect packets by reassembling them to read the payload. Packet fragmentation breaks the malicious payload into smaller fragments across multiple IP packets. If the firewall lacks the processing power or configuration to reassemble and inspect fragments dynamically, the individual fragments pass through uninspected and reassemble at the target host. Source Routing

: Wrapping attack payloads inside encrypted tunnels, blinding signature-based IDS sensors unless decryption is active. Denial of Service (DoS) and Noise Generation
