Red Hat Summit4.13. Restricting Access to mongod
To reduce the risk of data loss, configure only the apache and root users to have access to the MongoDB database daemon, mongod.
To restrict access to mongod on your Satellite Server, you must update your firewall configuration.
Procedure
Update the firewall configuration by entering the following command:
# firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 27017 -m owner --uid-owner apache -j ACCEPT \ && firewall-cmd --direct --add-rule ipv6 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 27017 -m owner --uid-owner apache -j ACCEPT \ && firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 27017 -m owner --uid-owner root -j ACCEPT \ && firewall-cmd --direct --add-rule ipv6 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 27017 -m owner --uid-owner root -j ACCEPT \ && firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -o lo -p \ tcp -m tcp --dport 27017 -j DROP \ && firewall-cmd --direct --add-rule ipv6 filter OUTPUT 1 -o lo -p \ tcp -m tcp --dport 27017 -j DROP \ && firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 28017 -m owner --uid-owner apache -j ACCEPT \ && firewall-cmd --direct --add-rule ipv6 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 28017 -m owner --uid-owner apache -j ACCEPT \ && firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 28017 -m owner --uid-owner root -j ACCEPT \ && firewall-cmd --direct --add-rule ipv6 filter OUTPUT 0 -o lo -p \ tcp -m tcp --dport 28017 -m owner --uid-owner root -j ACCEPT \ && firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -o lo -p \ tcp -m tcp --dport 28017 -j DROP \ && firewall-cmd --direct --add-rule ipv6 filter OUTPUT 1 -o lo -p \ tcp -m tcp --dport 28017 -j DROPMake the changes persistent:
