Behebungsmethode: Anleitung oder Infrastruktur-Patch

Note The following scripts will set the group to either audit or root based on the existence of the group audit. If the group audit doesn't exist, or the log_group parameter is already set to root, the appropriate group is determined to be the group root Run the following script to configure the audit log files to be owned by appropriate group: #!/usr/bin/env bash { l_group=""; grep -Pq '^audit:' /etc/group && l_group="audit" [ -z "$l_group" ] || [ "$(awk -F= '$1~/^\s*log_group\s*$/{print $2}' /etc/audit/auditd.conf | xargs)" = root ] && l_group="root" find $(dirname $(awk -F"=" '/^\s*log_file\s*=\s*/ {print $2}' /etc/audit/auditd.conf | xargs)) -type f \( ! -group root -a ! -group audit \) …
