Description
Journald (via systemd-journal-remote ) supports the ability to send
log events it gathers to a remote log host or to receive messages
from remote hosts, thus enabling centralised log management.
Rationale
Storing log data on a remote host protects log integrity from local
attacks. If an attacker gains root access on the local system, they
could tamper with or remove log data that is stored on the local system.
Shell script
The following script can be run on the host to remediate the issue.
#!/bin/bash
# Remediation is applicable only in certain platforms
if [ ! -f /.dockerenv ] && [ ! -f /run/.containerenv ]; then
DEBIAN_FRONTEND=noninteractive apt-get install -y "systemd-journal-remote"
else
>&2 echo 'Remediation is not applicable, nothing was done'
fi
Ansible playbook
The following playbook can be run with Ansible to remediate the issue.
