Frequently Asked Questions

Everything you need to know about website security and compliance

  • What is website security?

    Website security is the protection of websites and web applications from cyber threats and vulnerabilities. It includes measures to protect sensitive data, prevent unauthorized access, and maintain the integrity and availability of web services. Key aspects include secure coding practices, proper configuration of security headers, regular updates, and implementing protective measures like WAF (Web Application Firewall).

  • How to check website security?

    The easiest way to check your website security is to enter your website URL above, which will scan for vulnerabilities and security headers. For a comprehensive security assessment, you should: 1) Verify HTTP security headers implementation 2) Check SSL/TLS configuration 3) Review access controls and authentication mechanisms 4) Conduct regular penetration testing 5) Monitor server logs for suspicious activities 6) Verify compliance with security standards.

  • What compliance standards should my website meet (PCI, SOC, ISO27001)?

    Different compliance standards apply based on your business type: PCI DSS is mandatory if you handle credit card data, SOC 2 demonstrates secure data handling practices, and ISO 27001 provides a framework for information security management. Each standard has specific requirements for security controls, monitoring, and documentation.

  • What are HTTP headers?

    HTTP headers are key-value pairs sent in HTTP requests and responses that provide essential information about the transaction and security controls. Security-related headers help protect against common web vulnerabilities like XSS, CSRF, and clickjacking by instructing browsers how to handle the website's content.

  • Which HTTP security headers are required?

    Essential security headers include: Content-Security-Policy (CSP) to prevent XSS attacks, X-Frame-Options to prevent clickjacking, Strict-Transport-Security (HSTS) to enforce HTTPS, X-Content-Type-Options to prevent MIME-type sniffing, and X-XSS-Protection for additional XSS protection. The specific headers needed depend on your application's requirements.

  • How to configure HTTP headers?

    HTTP headers can be configured at different levels: 1) Web server configuration (Apache, Nginx) 2) Application code 3) Cloud platform settings 4) Content Delivery Network (CDN) configuration. The implementation method depends on your hosting environment and technology stack. Always test header configurations in a staging environment first.

  • Why is a WAF (Web Application Firewall) required?

    A WAF provides an additional security layer by filtering and monitoring HTTP traffic between web applications and the Internet. It protects against common web exploits like SQL injection, cross-site scripting (XSS), file inclusion, and security misconfigurations. WAFs can also help with DDoS protection and ensure compliance with security standards.

  • How important is keeping dependencies updated?

    Regular updates of dependencies (packages, CMS, plugins) is crucial for security because: 1) It patches known vulnerabilities 2) Fixes security bugs 3) Implements latest security features 4) Ensures compatibility with security standards. Outdated dependencies are a common attack vector for cybercriminals.
