The default configuration for security_space_left_action
is SUSPEND, which actually only suspends audit logging.
Suspending audit logging can lead to security problems because the
system is no longer keeping track of which syscalls were made.
The security role sets the configuration to SYSLOG so
that messages are sent to syslog when the available disk space reaches a
low level. If syslog messages are being sent to remote servers, these
log messages should alert an administrator about the disk being almost
full. There are additional options available, like EXEC,
SINGLE or HALT.
To configure a different space_left_action, set the
following Ansible variable:
security_space_left_action: SYSLOGFor details on available settings and what they do, run
man auditd.conf. Some options can cause the host to go
offline until the issue is fixed. Deployers are urged to
carefully read the auditd documentation prior to
changing the space_left_action setting from the
default.
