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 SLES for vRealize 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 SLES for vRealize to not use UDP for NIS and NIS+. Consult vendor documentation for the required procedure.
