SV-35147r1_rule The system must not use UDP for Network Information System (NIS/NIS+).

Vulnerability discussion

Implementing NIS or NIS+ under UDP may make the system more susceptible to a Denial of Service attack and does not provide the same quality of service as TCP.

Check content

If the system does not use NIS or NIS+, this is not applicable. Check if NIS or NIS+ is implemented using UDP. # rpcinfo -p | grep yp | grep udp If NIS or NIS+ is implemented using UDP, this is a finding.

Fix text

Configure the system to not use UDP for NIS and NIS+. HP-UX specific documentation (note the major version of NIS+ currently running) should be consulted for the required procedure.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
