Imagine waking up to find your organization's most sensitive data exposed online, or your personal identity stolen. In today's interconnected world, these scenarios aren't just possible-they're increasingly common. At the heart of preventing such disasters lies the CIA triad: Confidentiality prevents unauthorized access to data, Integrity ensures information remains unaltered, and Availability guarantees systems work when needed. When Springfield Nuclear Plant sends reactor specifications, encryption ensures only authorized recipients can read them. Meanwhile, hashing algorithms verify commands haven't been tampered with during transmission, and redundant systems ensure 24/7 operation. This layered approach-defense-in-depth-means that when one security measure fails, others remain effective. Think of it like protecting your home: you have locks, alarms, cameras, and perhaps a guard dog-multiple layers working together.
