Security Audit

Is this safe?

---

When To Run

• Before deploy
• After adding auth/credentials
• New endpoints
• External inputs

---

What To Check

1. Credentials

# Hardcoded secrets?
grep -rn "sk-\|api_key\|password\|secret" . --include="*.js"
grep -rn "Bearer\|Token" . --include="*.js"

Check	Issue	Fix
Hardcoded API key	HIGH	Use env var
Password in code	HIGH	Use env
Token in logs	MEDIUM	Redact

2. Inputs

// Never trust user input
req.params.id
req.body.data
query.string

Check	Issue	Fix
SQL from input	HIGH	Parameterize
Eval input	HIGH	Remove eval
Shell from input	HIGH	No shell
File from input	HIGH	Validate path

3. Auth

// Check auth exists
function protected() {
  if (!req.user) return error
  // Good
}

Check	Issue	Fix
No auth check	HIGH	Add auth
Auth bypassed	HIGH	Fix
Weak auth	MEDIUM	Strengthen

4. Network

Check	Issue
HTTP not HTTPS	Use HTTPS
Credentials in URL	Headers only
No CORS	Set CORS

5. Filesystem

// Check file access
fs.readFile(userPath)

Check	Issue	Fix
Path traversal	HIGH	Sanitize
Read any file	HIGH	Validate
Write anywhere	HIGH	Restrict
