Detection Signatures
This lesson covers Detection Signatures in the context of SYN Flood and TCP Attacks. Topics include: NetFlow export, sysctl net.ipv4.tcp_max_syn_backlog, nginx limit_req_zone. Educational and defensive use only.
Code Example
// ML anomaly detection
// Train on normal traffic
// Flag deviations from baselineCommands & References
- NetFlow export
- sysctl net.ipv4.tcp_max_syn_backlog
- nginx limit_req_zone
Lab Steps
- Set up your lab: NetFlow export
- Understand the attack or defense mechanism.
- Apply in a controlled environment.
- Document findings.
- Consider mitigation strategies.
Exercises
- Research recent DDoS incidents.
- Design a defense for a sample scenario.
- Review legal implications.
- Practice incident response.
