Secure Coding in Node.js🔹 Key idea: Secure Node.js applications require strict control over execution context and defaults.🔹 Strict Mode Enables safer JavaScript execution Prevents accidental global variables Forces explicit variable declarations 👉 Key Insight Strict mode reduces “silent” security bugs caused by sloppy scope handling2. HTTP Security Headers (Defense Layer)🔹 Tool: Helmet.js🔹 What it does: Automatically sets important security headers in Express apps.🔹 Key headers it manages: Content Security Policy (CSP) → blocks malicious scripts HTTP Strict Transport Security (HSTS) → forces HTTPS XSS Protection headers → reduces injection risks 👉 Key Insight Headers act as a browser-level security shield3. Secure Cookies🔹 Important flags: HttpOnly Blocks JavaScript access to cookies Secure Ensures cookies are only sent over HTTPS 👉 Key Insight Even if XSS happens, HttpOnly cookies cannot be stolen via JS4. Regular Expression Denial of Service (ReDoS)🔹 What it is: A performance attack exploiting bad regex patterns🔹 How it works: Complex input causes exponential backtracking CPU usage spikes Server becomes unresponsive 🔹 Common risk area: Email validation Input sanitization 👉 Key Insight A “valid” input can still be a computational attack5. Preventing ReDoS Attacks🔹 Strategies: Avoid overly complex regex patterns Limit input length Use safe validation libraries Benchmark regex performance 👉 Key Insight Security includes performance safety, not just access control6. Information Disclosure Risks🔹 Problem: Attackers learn stack/framework details from responses7.
