Description
Verify the operating system is configured to disable non-essential capabilities. The most secure way of ensuring a non-essential capability is disabled is to not have the capability installed. When an application uses Generic Security Services API (GSSAPI), typically it will have direct access to its security credentials, and all cryptographic operations are performed in the application's process. This is undesirable, but "gssproxy" can help in almost all use cases. It provides privilege separation to applications using the GSSAPI: The gssproxy daemon runs on the system, holds the application's credentials, and performs operations on behalf of the application.
