Disable Apport Service

An XCCDF Rule

Description

The Apport modifies certain kernel configuration values at runtime which may decrease the overall security of the system and expose sensitive data. The apport service can be disabled with the following command: 
$ sudo systemctl mask --now apport.service

Rationale

The Apport service modifies the kernel fs.suid_dumpable configuration at runtime which prevents other hardening from being persistent. Disabling the service prevents this behavior.
