Building systems that resist attack

No single wall stops a determined attacker, so real security is built in layers on one assumption: a breach will eventually happen. Learn the practical defender's playbook, least privilege, network segmentation and zero trust, patching, encryption done right, and the detection and incident response that limit the damage when prevention fails, each mapped to the attack stages it defeats.
