Disabling auto deployment of applications

BajaNivel 2Automatizadatomcat

Descripción

Tomcat allows auto deployment of applications while Tomcat is running. It is recommended that this capability be disabled. Every Host element in server.xml must set autoDeploy="false" (the default is true). 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.

Cómo se verifica

Método de auditoría: Comando de shell

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)}' "$1" | tr '\n\t\r' '   ' | tr '<' '\n'; }; s=$(x "$B/conf/server.xml") || exit 1; printf '%s\n' "$s" | awk 'function at(n,  r){if(match($0,"[[:space:]]" n "[[:space:]]*=[[:space:]]*[\"\047][^\"\047]*")){r=substr($0,RSTART,RLENGTH); sub(/^[^=]*=[[:space:]]*./,"",r); return r} return "-unset-"} /^Host[[:space:]]/{n++; if(at("autoDeploy")!="false") bad=1} END{print (n>0&&!bad)?"compliant":"noncompliant"}'

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Set autoDeploy="false" on each <Host> in server.xml. Restart Tomcat afterwards.
