Ensure access to the /etc/rsyslog.d directory is configured

MediumLevel 1Automatedlinux

Description

The /etc/rsyslog.d/ directory holds drop-in rsyslog configuration files ending in .conf. The directory should be owned by root, group-owned by root, and not writable by any account other than root so that unauthorized users cannot add, remove, or replace rsyslog configuration fragments.

How it is checked

Audit method: Shell command

shell

alt0() { command -v find >/dev/null 2>&1 || { echo "step1: find not installed"; return 1; }; o=$(bash -c 'find /etc/rsyslog.d/ -maxdepth 0 -type d \( ! -user root -o ! -group root - o -perm /0022 \) 2>/dev/null' 2>/dev/null); [ -z "$o" ] || { echo "step1: $o" | head -c 300; return 1; }; }; if alt0; then echo compliant; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following commands to set ownership to root:root and remove group and other write from the directory: # chown root:root /etc/rsyslog.d # chmod g-w,o-w /etc/rsyslog.d
