Configuring Cloudflare to exclude browser integrity checks for specific Autonomous System Numbers (ASNs) involves customizing security settings to allow traffic from designated ASNs without undergoing browser integrity checks. This customization can be beneficial for ensuring uninterrupted access to your website or application for legitimate users while still maintaining security against malicious traffic. Below are several key points outlining how to exclude browser integrity checks for ASNs in Cloudflare:
1. Access Cloudflare Dashboard:
- Login: Access the Cloudflare dashboard by logging into your Cloudflare account using your credentials.
- Select Domain: Choose the domain for which you want to configure security settings.
2. Navigate to Firewall Settings:
- Go to Firewall: In the Cloudflare dashboard, navigate to the "Firewall" section, typically located in the main menu or sidebar.
3. Configure Firewall Rules:
- Create Firewall Rule: Create a new firewall rule by clicking on the "Create Firewall Rule" button or similar option.
- Define Conditions: Define the conditions for the firewall rule to match traffic from specific ASNs. This typically involves specifying the ASN(s) you want to exclude from browser integrity checks.
4. Specify ASN Exclusions:
- Choose Field: Select the appropriate field for specifying ASN exclusions. This may vary depending on the firewall rule configuration interface but typically involves choosing the "ASN" field or similar option.
- Enter ASN(s): Enter the ASN(s) for which you want to exclude browser integrity checks. You can specify single ASNs or ranges of ASNs as needed.
5. Set Action:
- Select Action: Choose the action to apply to traffic that matches the specified conditions. In this case, select an action that excludes traffic from the specified ASNs from browser integrity checks.
- Exclude from Browser Integrity Check: Select the option to exclude traffic from the specified ASNs from browser integrity checks. This ensures that traffic from these ASNs will not be subjected to browser integrity checks and will be allowed to access your website or application without interruption.
6. Save Changes:
- Review and Save: Review the configured firewall rule to ensure it accurately reflects your requirements.
- Save Rule: Once you are satisfied with the configuration, save the firewall rule to apply the changes to your Cloudflare settings.
7. Test and Monitor:
- Test Exclusions: Test the configured firewall rule to verify that traffic from the specified ASNs is excluded from browser integrity checks and can access your website or application as expected.
- Monitor Traffic: Monitor traffic logs and analytics to ensure that the configured exclusions are working correctly and that legitimate traffic from the specified ASNs is not being inadvertently blocked or subjected to security checks.
8. Adjust Settings as Needed:
- Fine-Tune Exclusions: If necessary, fine-tune the configured firewall rule to adjust the list of excluded ASNs or modify other settings based on changing requirements or feedback from monitoring traffic patterns.
- Stay Updated: Stay informed about updates and changes to Cloudflare's security features and best practices for managing firewall rules to ensure ongoing effectiveness and security.
9. Considerations and Best Practices:
- Security Implications: While excluding specific ASNs from browser integrity checks can improve accessibility for legitimate users, it's essential to consider the potential security implications and carefully assess the risk of allowing traffic from these ASNs without undergoing security checks.
- Regular Review: Regularly review and update firewall rules and security settings to adapt to evolving threats, changes in traffic patterns, and updates to your website or application.
- Collaboration: Collaborate with security experts and stakeholders to ensure that security measures are aligned with business requirements and risk tolerance levels.
- Documentation: Document the configured firewall rules and security settings to maintain a clear record of the configured exclusions and facilitate troubleshooting and auditing processes.
In summary, configuring Cloudflare to exclude browser integrity checks for specific Autonomous System Numbers (ASNs) involves customizing firewall rules to allow traffic from designated ASNs without undergoing security checks. By carefully configuring these exclusions and monitoring traffic patterns, you can ensure uninterrupted access to your website or application for legitimate users while maintaining robust security against malicious traffic. Collaboration with security experts and stakeholders and regular review and adjustment of security settings are essential for maintaining effective security measures and protecting your online assets.
