Security Control Bypass and Defense Evasion Questions

Focuses on attacker techniques and defensive responses related to bypassing or evading security controls. Topics include common controls such as firewalls, intrusion detection systems, endpoint detection and response, web application firewalls, and how adversaries attempt to evade them using methods like traffic obfuscation, encryption tunneling, timing based evasion, payload and tool obfuscation, living off the land techniques, protocol misuse, and content polymorphism. Also covers the defender perspective: telemetry collection, detection engineering, tuning signatures, behavioral detection, threat modeling, hardening controls, and tradeoffs between detection fidelity and operational cost.
