nice concept of C&NS

1. Web Security Considerations Authentication | Data Protection | Application Security | Compliance

2. Authentication & Access Control • Strong password policies and secure storage (bcrypt, Argon2) • Multi-Factor Authentication (MFA) • Secure session management (timeouts, regeneration) • Role-Based and Attribute-Based Access Control • Principle of Least Privilege

3. Data Protection • Use HTTPS with TLS, enable HSTS • Encrypt sensitive data at rest and in backups • Avoid storing unnecessary personal data • Use hashing + salting for passwords • Tokenization for sensitive fields (e.g., credit cards)

4. Input Validation & Output Encoding • Validate inputs on client and server side • Use parameterized queries to prevent SQL injection • Sanitize inputs to block XSS and injections • Escape/encode output for HTML, JSON, XML • Secure file uploads (types, size, malware scan)

5. Session Management • Secure cookies with HttpOnly, Secure, SameSite flags • Limit session lifetime and reauthenticate for sensitive actions • Protect against session fixation (regenerate IDs) • Guard against session hijacking (IP/device binding if needed)

6. Application Security Controls • Content Security Policy (CSP) to restrict resource loading • CSRF protection using tokens • Rate limiting and throttling for brute force prevention • Proper error handling (no sensitive details in responses) • Code reviews and security testing

7. Server & Network Security • Keep OS, servers, and frameworks patched • Deploy Web Application Firewalls (WAF) • Harden configurations (disable directory listing, weak ciphers) • Use IDS/IPS and firewalls • Remove default accounts and unused services

8. Monitoring & Logging • Log authentication, access, and privilege changes • Centralized and tamper-proof logging • Real-time anomaly detection and alerts • Regular log audits to detect incidents

9. Third-party & API Security • Secure APIs with OAuth 2.0 / JWT • Apply rate limiting and validation • Regular vulnerability scans of dependencies • Use only trusted libraries and vendors • Enforce least privilege in integrations

10. User Awareness & Policies • Educate users on phishing, social engineering • Promote safe password practices • Enforce company security policies (BYOD, usage) • Conduct regular training and awareness programs

11. Compliance & Standards • Follow OWASP Top 10 and CIS Benchmarks • Ensure compliance with GDPR, HIPAA, PCI DSS • Regular penetration tests and vulnerability assessments • Enforce secure coding and configuration baselines
