Ensure access on /var/tmp/snmpd.log is configured

MoyenneNiveau 1Automatiséeaix

Description

The /var/tmp/snmpd.log is the logfile used by snmpd daemon, and contains network and machine related information. The /var/tmp/snmpd.log logfile contains sensitive information through which an attacker can find out about the SNMP deployment architecture in your network. This log file must be secured from unauthorized access. Audit: compares `ls -ld` mode (or more restrictive), owner and group; an absent file is compliant.

r=compliant; for f in /var/tmp/snmpd.log; do if [ -e "$f" ]; then set -- $(ls -ld "$f"); s=$(printf '%s %s %s\n' "$1" "$3" "$4" | awk -v m='rw-r-----' -v o='root' -v g='system' '{ok=1; for(i=1;i<=9;i++) if(substr(m,i,1)=="-" && substr($1,i+1,1)!="-") ok=0; if(o!="" && $2 !~ ("^(" o ")$")) ok=0; if(g!="" && $3 !~ ("^(" g ")$")) ok=0; print (ok ? "ok" : $0)}'); [ "$s" = ok ] || r="$f: $s"; else :; fi; done; echo "$r"
