Discussion

The sprayd service is used as a tool to generate UDP packets for testing and diagnosing network problems. The service must be disabled if NFS is not in use, as it can be used by attackers in a Distributed Denial of Service (DDoS) attack.

Check Content

From the command prompt, execute the following command: 
# grep "^sprayd[[:blank:]]" /etc/inetd.conf

If there is any output from the command, this is a finding.

Fix Text

In "/etc/inetd.conf", comment out the "sprayd" entry by running command: 
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'sprayd' -p 'udp'

Restart inetd:
# refresh -s inetd
