Provide methods to add security headers to the site using Solid Security

A list of common security headers:

• HTTP Strict Transport Security (HSTS)

• X-Frame-Options

• X-XSS-Protection

• X-Content-Type-Options

• Referrer-Policy

• Feature-Policy

• Content-Security-Policy (CSP)

1. Advanced Two-Factor Authentication (2FA) with Device Trust Option

Description: This feature extends the Two-Factor Authentication by allowing users to mark a device as trusted. After the initial authentication, users can choose not to enter an authentication code on this device for the next 30 days. The device trust option strikes an ideal balance between security and user-friendliness, enabling frequently used devices to be accessed securely and conveniently.

Benefit: This enhances the user experience by simplifying the login process for regular customers and vendors without compromising security. At the same time, rarely used devices remain protected by an additional layer of security.

2. Extended WooCommerce Integration

Description: Solid Security’s integration with WooCommerce is extended to enable reCAPTCHA and Two-Factor Authentication on all relevant WooCommerce forms (e.g., login, registration, and checkout forms). Additionally, this extension could be applied to specific actions, such as adding payment information or changing shipping addresses, to provide extra protection for these sensitive areas.

Benefit: The extended integration makes the entire WooCommerce platform more resilient to security threats by safeguarding critical user actions with additional security measures. This strengthens customer trust in the platform and minimizes the risk of security incidents.

Summary of the Proposal

These proposed developments for Solid Security in WooCommerce and WCFM aim to create a secure and user-friendly environment. By introducing advanced 2FA options, deeper integration of security measures in WooCommerce, and implementing role-based security policies, the platform’s security will be significantly enhanced. These measures help vendors and administrators protect their accounts and data from unauthorized access and other security threats effectively.

1. Mixed Content Fixer
   Description:
   This feature automatically replaces all non-secure (http) content with secure (https) content on the front end of the website. The function hooks into the template redirect and ensures that all content is served securely, preventing mixed content issues.

Implementation:

phpCode kopieren
function fix_mixed_content() {    if (is_admin()) return;    ob_start(function ($buffer) {        $ssl_host = 'https://' . $_SERVER['HTTP_HOST'];        $content = str_replace('http://', $ssl_host . '/', $buffer);        return $content;    }); }
add_action('template_redirect', 'fix_mixed_content');

1. Mixed Content Fixer - Back-End
   Description:
   This feature performs a similar function as the front-end Mixed Content Fixer but applies specifically to the WordPress admin area. It ensures that all admin content is served over https, thereby fixing any mixed content issues in the back-end.

Implementation:

phpCode kopieren
function fix_mixed_content_backend() {    if (!is_admin()) return;    ob_start(function ($buffer) {        $ssl_host = 'https://' . $_SERVER['HTTP_HOST'];        $content is replaced by the buffer buffer);        return $content;    }); }
add_action('admin_init', 'fix_mixed_content_backend');

1. 301 .htaccess Redirect
   Description:
   This feature forces all non-secure (http) requests to be redirected to the secure (https) version of the website using a 301 redirect. It ensures that all traffic is securely transmitted by redirecting requests before content is served.

Implementation:

phpCode kopieren
function force_ssl_redirect() {    if (!is_ssl()) {        wp_redirect('https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 301);        exit();    } }
add_action('template_redirect', 'force_ssl_redirect');

1. Disable "Anyone Can Register"
   Description:
   This feature disables the option that allows anyone to register an account on the website. It enhances security by preventing unauthorized users from creating accounts.

Implementation:

phpCode kopieren
add_action('init', function() {    update_option('users_can_register', 0); });

1. Hide WordPress Version
   Description:
   This feature removes the WordPress version number from the site’s header, reducing the risk of targeted attacks based on known vulnerabilities in specific WordPress versions.

Implementation:

phpCode kopieren
remove_action('wp_head', 'wp_generator');

1. Prevent Login Feedback
   Description:
   This feature customizes the error message displayed during failed login attempts. Instead of revealing whether the username or password is incorrect, it returns a generic error message, which prevents potential attackers from gaining information about valid usernames.

Implementation:

phpCode kopieren
function no_wordpress_errors(){    return 'Invalid credentials.'; }
add_filter('login_errors', 'no_wordpress_errors');

1. Disable User Enumeration
   Description:
   This feature blocks attempts to enumerate WordPress user IDs through the URL, which is a common technique used by attackers to discover usernames for brute-force attacks.

Implementation:

phpCode kopieren
if (!is_admin()) {    if (preg_match('/author=([0-9]*)/i', $_SERVER['QUERY_STRING'])) die(); }

Description:
To offer more privacy-conscious alternatives to Google reCAPTCHA, the integration of hCaptcha and Image CAPTCHA is proposed. These alternatives provide similar levels of protection against spam and automated bots without relying on Google services, making them more suitable for GDPR (DSGVO) compliance.

Benefits:

1. Privacy and Compliance:

   • hCaptcha: Unlike Google reCAPTCHA, hCaptcha is designed with privacy in mind, and it does not track users across the web. It offers robust security while respecting user privacy, making it a preferred choice for websites concerned with GDPR compliance.
   • Image CAPTCHA: This is a simple CAPTCHA method that does not rely on third-party services. Users are required to identify specific images or patterns, ensuring that the verification process remains entirely under the control of the website owner, without sending data to external servers.

2. Ease of Integration:

   • Both hCaptcha and Image CAPTCHA can be easily integrated into WooCommerce, WCFM, and other WordPress forms (such as login, registration, and checkout pages). The implementation involves minor changes to the form templates and settings, allowing administrators to select their preferred CAPTCHA solution.

3. Customization and Flexibility:

   • hCaptcha: Offers customization options that allow website owners to adjust the difficulty level and appearance to match their website’s design. It also provides options for monetization, where the website owner can earn rewards for solving CAPTCHAs.
   • Image CAPTCHA: Allows full customization of the CAPTCHA challenges, enabling site owners to create unique challenges that align with their brand’s theme or user base.

4. User Experience:

   • Both alternatives offer a user-friendly experience, with hCaptcha providing a straightforward challenge that is similar in operation to reCAPTCHA, and Image CAPTCHA offering simple and engaging image-based challenges. This ensures that the verification process is not intrusive, thereby maintaining a smooth user experience.

Implementation:

• hCaptcha: Integrate hCaptcha through the WordPress plugin ecosystem or directly via API. Add settings in the WooCommerce and WCFM admin panels to easily switch between CAPTCHA services.
• Image CAPTCHA: Implement Image CAPTCHA by adding a customizable CAPTCHA challenge option within the WooCommerce and WCFM settings. This can be managed directly from the WordPress dashboard, allowing administrators to upload custom images or choose from a predefined set.

Conclusion: Supporting hCaptcha and Image CAPTCHA provides a robust, privacy-friendly alternative to Google reCAPTCHA, ensuring compliance with GDPR (DSGVO) and offering flexibility and customization to website owners. By integrating these options, WooCommerce and WCFM can enhance security while respecting user privacy and improving the overall user experience.

Solid Security users should have the ability to customize the Solid Security email templates: logo, header, footer, colors, continue button.
