Application vulnerabilities, runtime patching and message security
How to counteract Mule application vulnerabilities by deployment option: isolating browser-facing apps from the shared cloudhub.io domain, CloudHub 1.0 security patching and the monthly date-patch cycle, protecting property values on CloudHub 1.0 and CloudHub 2.0, Last-Mile Security, and message-level protection with the Cryptography module.
Analyze and counteract potential security vulnerabilities of Mule applications.
~7 min read · 6 practice questions
What the exam expects
- Recognize why browser-facing applications on the shared cloudhub.io domain are exposed, and move them to an isolated domain.
- Explain how CloudHub 1.0 handles operating system, JVM and Mule runtime vulnerabilities, including the security patch SLA, live patching and the monthly date-patch schedule.
- Choose how to keep a sensitive property value hidden on CloudHub 1.0, CloudHub 2.0, hybrid and Runtime Fabric deployments.
- Decide when TLS must terminate inside the Mule application rather than at the CloudHub 2.0 ingress.
- Select the Cryptography module strategy that protects a message itself, independent of the transport.
Date patch: the monthly backward-compatible Mule update, versioned Major.Minor.Patch - Date (CloudHub Runtime Continuous Updates). Protected property: a CloudHub 2.0 property whose value is never viewable or retrievable after it is set (Protecting App Property Values). Safely hidden property: the CloudHub 1.0 equivalent, listed under secureProperties (Safely Hide Application Properties). Last-Mile Security: TLS for forwarded HTTPS connections terminates in the application (Deploying Apps to Private Spaces).
