In Android, what must you include in the Network Security Configuration to ensure data is sent properly?

Including system CA certificates or public Managed Cluster ActiveGate certificates in the Network Security Configuration is essential for ensuring that data is sent properly in Android applications. This configuration helps in establishing a secure connection by validating that the server you are communicating with is trusted.

Using system CA certificates allows your app to recognize and trust certificates issued by trusted Certificate Authorities (CAs), ensuring that the communication is encrypted and secure. Managed Cluster ActiveGate certificates serve a similar purpose, providing an additional layer where the app can verify that the endpoint it interacts with is legitimate. This is particularly important for maintaining data integrity and security in applications that transmit sensitive information.

In contrast, relying solely on self-signed certificates or allowing no specific configuration can result in increased vulnerability to attacks, such as man-in-the-middle attacks. Automatically generated certificates by Dynatrace might not cover all scenarios and could potentially lead to trust issues if not used judiciously. Therefore, establishing a robust configuration using recognized and trusted certificates is paramount for secure data transmission in an Android environment.
