CYBERSECURITY
A boundary for every request
Verify identity and resource permissions on the server. Bind SQL parameters, encode output for its destination context, and protect cookie-authenticated state changes against CSRF.
CYBERSECURITY
Use OWASP as a starting point
The OWASP Top 10:2025 is an awareness framework, not a complete verification plan. Relate access control, configuration and supply-chain risks to your application. SSRF controls must cover resolved addresses and redirects.

A verifiable release gate
Review authentication, uploads and error handling. Pin dependencies and keep secrets out of source control. Re-run security checks after fixes and retain evidence with the release.
PHP / PDO
Keep data separate from instructions
Bind data values with prepared statements. Encode untrusted text for HTML output; other contexts require their own encoders.
$query = $pdo->prepare("SELECT title FROM pages WHERE slug = ?");
$query->execute([$slug]);
echo htmlspecialchars($title, ENT_QUOTES | ENT_SUBSTITUTE, "UTF-8");YOUR REVIEW
