Stop Trusting Input: 3 RULES
Thank you to ThreatLocker for sponsoring this video and my trip to Black Hat USA 2025.
Want to write secure code without becoming a full-time security engineer? In this video, Tanya Janca (SheHacksPurple) breaks down the 3 essentials every developer should use on day one:
Validate & sanitize all inputs to block malicious characters.
Output encode everything you render so it’s treated as text, not code.
Use parameterized queries for every DB call to shut down SQL injection.
Stop copy-pasting from forums and start shipping code that resists XSS and SQLi by design. Tanya also points to her secure-coding book covering 10 languages and 8 frameworks for deeper, practical guidance.
You’ll learn: input validation vs. sanitization, output encoding basics, safe DB access patterns, and a simple mental checklist to make your app safer today.
