2025/10/22

Every cybersecurity role depends on understanding how data moves, and this episode makes the OSI and TCP/IP models come alive. You’ll hear how each layer—from physical signals to application data—adds structure, context, and control. We discuss how encapsulation works, why headers matter, and where vulnerabilities typically appear as traffic ascends or descends these layers. Knowing which layer a problem belongs to is key not only for the exam but for troubleshooting in real networks, where

Episode 12 — Security Awareness: Human Risk Controls

Certified: SANS GIAC GSEC Audio Course ·

2025/10/22

Technology alone can’t stop breaches if people remain untrained, and this episode focuses on the human side of defense. You’ll hear how awareness programs translate policy into behavior by teaching staff to recognize, resist, and report potential threats. The episode unpacks what makes awareness effective—clear goals, relatable scenarios, and reinforcement through repetition rather than one-time slideshows. It also explains how awareness differs from training: awareness shapes mindset,

Certified: SANS GIAC GSEC Audio Course ·

2025/10/22

This episode explains how security standards and baselines transform policy intent into measurable, repeatable action. You’ll learn how standards define the “what” and “how” behind each policy requirement—like password length, patch frequency, or encryption algorithms—so that compliance can be verified instead of assumed. We also explore baselines as reference configurations that establish the known-good state for systems, users, or networks. By setting these benchmarks early, teams can
