Common Development Pitfalls

Pitfall 1: "Security by Obscurity"

Problem: Hiding how things work instead of securing them Reality: Attackers will reverse engineer Solution: Assume attackers know everything except keys

Pitfall 2: "We'll Patch It Later"

Problem: Shipping with known vulnerabilities Reality: Patches may never happen Solution: Fix critical issues before release

Pitfall 3: "It's Not Connected"

Problem: Ignoring non-network attack vectors Reality: USB, physical access still exist Solution: Threat model all interfaces

Pitfall 4: "The Vendor Handles Security"

Problem: Blindly trusting third-party components Reality: You're responsible for everything Solution: Verify and monitor all components

Pitfall 5: "Testing Will Find Everything"

Problem: Over-reliance on testing Reality: Can't test all possibilities Solution: Defense in depth approach
