TMA-TOMCAT-4.4

Restrict access to Tomcat logs directory

中レベル 1自動tomcat

説明

The Tomcat $CATALINA_HOME/logs directory contains Tomcat logs. It is recommended that the ownership of this directory be tomcat_admin:tomcat. It is also recommended that the permissions on this directory deny read, write, and execute for the world (o- rwx). $CATALINA_BASE/logs must not match -perm /o+rwx and must be owned by $TOMCAT_OWNER:$TOMCAT_GROUP; expects 0 findings. Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored. The expected owner/group are tomcat_admin:tomcat as in the benchmark; override with TOMCAT_OWNER / TOMCAT_GROUP.

チェック方法

監査方法: シェルコマンド

shell

B=${CATALINA_BASE:-/opt/tomcat}; H=${CATALINA_HOME:-$B}; O=${TOMCAT_OWNER:-tomcat_admin}; G=${TOMCAT_GROUP:-tomcat}; x(){ [ -r "$1" ] || return 1; awk 'BEGIN{RS="<!--"} NR==1{print;next} {i=index($0,"-->"); if(i) print substr($0,i+3)}' "$1" | tr '\n\t\r' '   ' | tr '<' '\n'; }; p="$B/logs"; [ -e "$p" ] || exit 1; find -L "$p" -maxdepth 0 \( -perm /o+rwx -o ! -user "$O" -o ! -group "$G" \) -print 2>/dev/null | wc -l

期待される出力: 0
