    Protecting APIs with JWT Validation

    Cloudflare customers can now protect their APIs from broken authentication attacks by validating incoming JSON Web Tokens (JWTs) with API Gateway's JWT Validation. The release addresses feature requests for supporting the Bearer token format, creating multiple JWKS configs, validating JWTs sent in cookies, and excluding managed endpoints in a JWT validation rule. Broken authentication is a major threat in API security, and JWT validation helps enforce a positive security model for authenticated API users. JWTs provide short-lived sessions and enhanced security compared to other authentication methods. API attacks like missing or broken authentication, expired token reuse, and Broken Function Level Authorization attacks can be prevented with proper authentication and authorization. API Gateway's JWT Validation checks JWT signatures, expiration times, and the presence of authentication tokens to protect against these attacks. Cloudflare Access and custom Cloudflare Workers are other options for JWT validation, but API Gateway provides an easier and more manageable experience. Future releases will expand the capabilities of API Gateway, including generating and enforcing authorization policies and enhancing API management with Cloudflare.

    Migrating billions of records: moving our active DNS database while it’s in use

    Cloudflare undertook the complex task of migrating billions of DNS records from their main database cluster (**cfdb**) to a new cluster (**dnsdb**) to alleviate strain and improve scalability. The migration was meticulously planned to ensure no data loss and minimal downtime. Key steps included creating a change logging system, using triggers to capture updates, and implementing a replication process. The final migration resulted in improved database performance and reduced incident rates, setting the stage for future scalability.
