Solaris uses the "IPP" print service and can also use the Samba print service. Verify remote host access is limited. Procedure: # grep -i Listen /etc/apache/httpd-standalone-ipp.conf The /etc/apache/httpd-standalone-ipp.conf file must not contain a Listen *: or equivalent line. If the network address of the "Listen" line is unrestricted, this is a finding. # grep -i "Allow From" /etc/apache/httpd-standalone-ipp.conf The "Allow From" line within the "" element should limit access to the printers to @LOCAL and specific hosts. If the "Allow From" line contains "All", this is a finding. Verify guest access to printers shared via Samba is restricted according to GEN006235.
