Episode 48 — On-Prem Network Infrastructure: Power, HVAC, Fire Suppression, Redundancy

This episode covers on-premises infrastructure considerations that affect security and resilience, helping you answer CC questions where physical and operational realities determine availability and risk. You will learn why power, cooling, fire suppression, and environmental monitoring matter to security, and how failures in these areas can cause downtime, data loss, and unsafe conditions. We will discuss redundancy concepts such as uninterruptible power supplies, generators, redundant network links, and hardware failover, emphasizing how these support availability targets and disaster recovery planning. You will practice identifying the likely point of failure in scenarios where systems overheat, networks intermittently drop, or equipment is damaged due to poor environmental control. Real-world best practices will include regular testing of backup power, maintaining physical security around infrastructure rooms, monitoring for temperature and humidity drift, and documenting dependencies so continuity and recovery plans reflect the actual environment rather than assumptions.
