Who gets in, and what can they do? Fundamentals dictate two key rules here:
The "law of the land" for an organization. This includes everything from password complexity to how a laptop should be stored. Fundamentals of information systems security
Because the most sophisticated firewall can be bypassed by a single employee clicking a phishing link, education remains a core fundamental. 3. Layers of Defense (Defense in Depth) Who gets in, and what can they do

At the heart of every security policy lies the . These three concepts are the benchmark for any secure system:
Secure coding practices and regular patching.
Solid security never relies on a single "front door." Instead, it uses —a layered approach borrowed from medieval castle design: Physical Security: Locks, cameras, and biometric scanners.
