Fix Recommendation

Edit the SSH daemon config file and add/modify the "ListenAddress" network addresses:
# vi /etc/ssh/sshd_config

Restart SSH daemon:
# stopsrc -s sshd
# startsrc -s sshd

Check Contents

From the command prompt, run the following command to check if "ListenAddress" is defined in SSH config file:

# grep -i ListenAddress /etc/ssh/sshd_config | grep -v '^#'
ListenAddress 10.17.76.74

If no configuration is returned, or if a returned listen configuration contains addresses not permitted, this is a finding.
