Ethical Hacking — Sniffing & Spoofing: Detect, Analyze & Defend

See what attackers see — and close the doors they use. This hands-on module teaches network sniffing and spoofing from a defensive, ethical perspective. You’ll learn how packet capture, address spoofing, and MitM techniques work at a conceptual level, how to detect them in logs and network telemetry, and how to harden networks so those techniques fail. All exercises run in isolated, consented labs — never against live or unauthorized targets.

What You'll Learn

• Network traffic fundamentals: packets, frames, MAC vs IP addressing, ARP, and TCP/IP basics.
• Packet capture & analysis: how to read captures, identify suspicious flows, and extract Indicators of Compromise.
• Address spoofing concepts: ARP spoofing, IP source spoofing, and how attackers use them for interception.
• Man-in-the-Middle (MitM) theory: interception vectors, SSL/TLS implications, and detection signals.
• Detection & monitoring: build detection rules, tune alerts, and spot anomalous ARP/arp-cache behaviors and DNS anomalies.
• Defensive controls: switch hardening, ARP inspection, DHCP protections, encrypted channels, and network segmentation.
• Forensics & incident response: collect packet evidence, preserve chain-of-custody, and produce clear technical reports.
• Safe lab practice: authorized capture exercises, analysis templates, and repeatable scenarios for learning.
• Reporting & remediation: developer and ops-ready remediation steps, executive summaries, and playbooks.

Format & Benefits

• Format: concise video lessons + guided sandbox labs and downloadable analysis templates.
• Deliverables: packet capture reports, detection rules, remediation checklists, and a completion badge.
• Support: private forum, instructor office hours, and select lab reviews for early enrollees.
• Outcome: verifiable artifacts you can show employers — forensic captures, tuned detections, and hardened configs.

Why this module matters: sniffing and spoofing are common precursor techniques to larger attacks. Learn to detect them early, respond cleanly, and prevent attackers from intercepting sensitive traffic. Limited seats ensure personalized feedback — early enrollees receive bonus PCAP analysis templates and a one-on-one lab review as a reciprocity gift.

Ethical use only — all exercises use isolated, consented targets or public datasets. This training focuses on detection, defense, and incident response; it does not provide actionable instructions for attacking unauthorized systems.
