Hello, 
I will tell you how to secure your vps ssh by changing port. 
1st. Login with SSH (root) 
2nd. Type this command 

Terminal

nano /etc/ssh/sshd_config

You will get this if you are using CentOS

Terminal

GNU nano 2.3.1  File: /etc/ssh/sshd_config           
#       $OpenBSD: sshd_config,v 1.100 2016/08/15 12:32$
# This is the sshd server system-wide configuration fi$# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/usr$
# The strategy used for options in the default sshd_co$# OpenSSH is to specify options with their default val$# possible, but leave them commented.  Uncommented opt$# default value.

# If you want to change the port on a SELinux system, $# SELinux about this change.
# semanage port -a -t ssh_port_t -p tcp #PORTNUMBER
#
#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

Changw the port line to 

Terminal

Port 4/5NUMBERS HERE

And remove the #
EX:

Terminal

Port 9988

And then click CTRL + O
And press Enter to save the directory
And then type this command

Terminal

service sshd restart

And for Ubuntu do all of these steps but when you want to save do

Terminal

service ssh restart

Now reboot or just exit from PuTTy and change the port to 9988 (the changed port) and re connect
