What are the pros and cons of using xinetd for a web server running on a VPS. Assume the following measures have already been taken to secure the system:

  • system hardening, latest updates, minimal packages
  • strick iptables firewall
  • controlled/limited use of admin privileges
  • properly configured services
  • hardened web application
  • web application firewall
  • continuous vulnerability assessments
  • log monitoring
  • 2
    do you know what xinetd is for? your question is like: what are the pros and cons of a brown sofa when installing an alarm-device from company Foo – that guy from over there Jul 3 '14 at 5:51

  • nagios-nrpe, (mostly custom) services that doesnt have any limitiation build-in AND where iptables-access for those who administer these services is not wanted. xinted is just a tcpwrapper, not a service itself. docs.fedoraproject.org/en-US/Fedora/11/html/Security_Guide/… – that guy from over there Jul 16 '14 at 9:39
  • Thanks for sharing that link. I've been experimenting w/ using xinetd w/ SSH and I'm not really seeing any benefits it provides.Is is true that xinetd is being fazed out? – Python Novice Jul 16 '14 at 9:54

Putting an xinetd server in front of your web server will reduce security: in addition to any security holes in the web server, you now also are vulnerable to any security holes in xinetd. Any security measures you can apply through xinetd, you can apply instead through the firewall or the web server.
