Ensure access to rsyslog configuration files is configured

中等級 1自動化linux

說明

The main rsyslog configuration file /etc/rsyslog.conf and the drop-in configuration files ending in .conf under /etc/rsyslog.d/ control how rsyslog collects, filters, stores, and forwards system log data. These files should be owned by root, group-owned by root, and no more permissive than mode 0640, so that they can be modified only by root and are not readable by any account other than root.

檢查方式

稽核方法: Shell 指令

shell

alt0() { command -v find >/dev/null 2>&1 || { echo "step1: find not installed"; return 1; }; o=$(bash -c 'find /etc/rsyslog.conf -not -type l \( ! -user root -o ! -group root -o - perm /0137 \) 2>/dev/null' 2>/dev/null); [ -z "$o" ] || { echo "step1: $o" | head -c 300; return 1; }; command -v find >/dev/null 2>&1 || { echo "step2: find not installed"; return 1; }; o=$(bash -c 'find /etc/rsyslog.d/ -type f -name '"'"'*.conf'"'"' \( ! -user root -o ! -group root -o -perm /0137 \) 2>/dev/null' 2>/dev/null); [ -z "$o" ] || { echo "step2: $o" | head -c 300; return 1; }; }; if alt0; then echo compliant; fi

預期輸出: compliant

修補方式

修補方法: 操作指南或基礎設施修補檔

Run the following commands to set ownership to root:root and remove group write, all access for other accounts, and all execute bits from the rsyslog configuration files, resulting in mode 0640 or more restrictive: # chown root:root /etc/rsyslog.conf # chmod u-x,g-wx,o-rwx /etc/rsyslog.conf # find /etc/rsyslog.d/ -type f -name '*.conf' -exec chown root:root {} + # find /etc/rsyslog.d/ -type f -name '*.conf' -exec chmod u-x,g-wx,o-rwx {} +
