Certified: The Security+ Prepcast

Without reliable power, even the most secure systems are at risk of failure—and in many environments, loss of power is both a security and safety issue. In this episode, we explore how power resilience contributes to business continuity, starting with uninterruptible power supplies (UPS) that bridge short outages and allow graceful shutdowns. We cover the role of backup generators for longer-term outages, battery management systems, and fuel logistics in ensuring extended availability. Power monitoring systems can detect anomalies like voltage spikes, temperature fluctuations, or hardware degradation, allowing proactive maintenance before failures occur. We also touch on environmental controls like HVAC systems and physical safeguards that protect against overheating or physical tampering. Whether you’re managing a server room, a data center, or a remote field device, maintaining power resilience means anticipating both natural and human disruptions. Because when the power goes out, everything else depends on what you planned before it did.
