Title:
Ensure journald is not configured to receive logs from a remote client
Description:
Journald supports the ability to receive messages from remote hosts, thus acting as a log
server. Clients should not receive data from other hosts.
NOTE:
The same package, systemd-journal-remote , is used for both sending logs to
remote hosts and receiving incoming logs.
With regards to receiving logs, there are two services; systemd-journal-
remote.socket and systemd-journal-remote.service .
Rationale:
If a client is configured to also receive data, thus turning it into a server, the client system is
acting outside it's operational boundary.
Audit:
Run the following command to verify systemd-journal-remote.socket is not enabled:
# systemctl is-enabled systemd-journal-remote.socket
Verify the output matches:
masked
Remediation:
Run the following command to disable systemd-journal-remote.socket :
# systemctl --now mask systemd-journal-remote.socket
Parameter:
[yes/no]
Technical Mechanism:
Remediation:
Run the following command to disable systemd-journal-remote.socket :
# systemctl --now mask systemd-journal-remote.socket
