Use of an insecure channel - Docker
Description
The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime. Inform only the ports that your application needs and avoid exposing ports such as HTTP (80).
Impact
Capture confidential information and credentials in plain text.
Recommendation
Deploy the application over an encrypted communication channel, for instance, HTTPS with TLS.
Always try to reduce the attack surface and use EXPOSE to mark and document only the required ports in the Dockerfile.
Threat
Anonymous attacker on adjacent network performing a man-in-the-middle.
Expected Remediation Time
⌚ 15 minutes.
