Security breaches are expensive, embarrassing, and increasingly common. In 2026, web application security is not optional — it is a fundamental requirement.
The OWASP Top 10
Every developer should know the OWASP Top 10 security risks: injection attacks, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfiguration, XSS, insecure deserialization, using components with known vulnerabilities, and insufficient logging.
Authentication Best Practices
Use bcrypt or Argon2 for password hashing. Implement multi-factor authentication. Use secure session management with HttpOnly, Secure, and SameSite cookies. Never store passwords in plain text.
Input Validation
Never trust user input. Validate on both client and server side. Use parameterized queries to prevent SQL injection. Sanitize HTML output to prevent XSS attacks.
Infrastructure Security
Keep all dependencies updated. Use HTTPS everywhere. Configure Content Security Policy headers. Implement rate limiting. Regularly scan for vulnerabilities.
At PMtech
Security is built into our development process from day one. We follow OWASP guidelines, conduct regular security audits, and keep all dependencies up to date.
