# Ensure journald ForwardToSyslog is disabled
 
## Description{% #description %}

Data from journald should be kept in the confines of the service and not forwarded to other services.

## Rationale{% #rationale %}

If journald is the method for capturing logs, all logs of the system should be handled by journald and not forwarded to other logging mechanisms.

## Remediation{% #remediation %}

### Shell script{% #shell-script %}

The following script can be run on the host to remediate the issue.

```bash
#!/bin/bash

# Remediation is applicable only in certain platforms
if dpkg-query --show --showformat='${db:Status-Status}' 'linux-base' 2>/dev/null | grep -q '^installed$' && { dpkg-query --show --showformat='${db:Status-Status}' 'systemd' 2>/dev/null | grep -q '^installed$'; }; then

found=false

# set value in all files if they contain section or key
for f in $(echo -n "/etc/systemd/journald.conf.d/complianceascode_hardening.conf /etc/systemd/journald.conf.d/*.conf /etc/systemd/journald.conf"); do
    if [ ! -e "$f" ]; then
        continue
    fi

    # find key in section and change value
    if grep -qzosP "(?m)^[[:space:]]*\[Journal\]([^\n\[]*\n+)+?[[:space:]]*ForwardToSyslog" "$f"; then
        if ! grep -qzosP "(?m)^[[:space:]]*ForwardToSyslog[[:space:]]*=[[:space:]]*no" "$f"; then

            sed -i "/^[[:space:]]*ForwardToSyslog/s/\([[:blank:]]*=[[:blank:]]*\).*/\1no/" "$f"

        fi

        found=true

    # find section and add key = value to it
    elif grep -qs "^[[:space:]]*\[Journal\]" "$f"; then

            sed -i "/^[[:space:]]*\[Journal\]/a ForwardToSyslog=no" "$f"

            found=true
    fi
done

# if section not in any file, append section with key = value to FIRST file in files parameter
if ! $found ; then
    file=$(echo "/etc/systemd/journald.conf.d/complianceascode_hardening.conf /etc/systemd/journald.conf.d/*.conf /etc/systemd/journald.conf" | cut -f1 -d ' ')
    mkdir -p "$(dirname "$file")"

    echo -e "[Journal]\nForwardToSyslog=no" >> "$file"

fi

else
    >&2 echo 'Remediation is not applicable, nothing was done'
fi
```
