The declarative configuration file empowers applications to customize their network security settings without modifying application code. It uses XML format to specify which network traffic should be secure, which certificates to trust, and what security policies to enforce. For example, it allows developers to configure whether an application trusts user-installed certificate authorities or communicate only over HTTPS.
This configuration offers significant advantages by enhancing security posture and enabling fine-grained control over network communication. It prevents man-in-the-middle attacks, protects sensitive data, and ensures compliance with evolving security standards. Previously, implementing such security measures often required complex coding. This approach simplifies the process and makes security updates more manageable as changes to the file do not necessitate application recompilation.
